UAE Weather Alert: Dense Fog Prompts Red and Yellow Warnings as Autumn Season Gets Underway.

UAE Weather Forecast: Autumn Arrives as Fog Alerts Issued Across Several Areas

Weather conditions across the UAE are expected to remain generally fair to partly cloudy today, according to the latest forecast issued by the National Centre of Meteorology (NCM). The weather update comes as the country officially enters the autumn season following several months of hot summer conditions.

The transition into autumn marks a seasonal change in weather patterns across the UAE, although temperatures are expected to remain relatively high during the daytime. Residents can expect generally stable conditions across much of the country, with the possibility of increased cloud activity developing in some areas later in the day.

According to astronomical calculations released by a senior official, the autumn season will officially begin at 4.05am on Wednesday, September 23. The seasonal transition is expected to coincide with the appearance of several prominent stars and constellations in the eastern sky around dawn.

The constellations and celestial bodies identified in the astronomical forecast include Gemini, Taurus, Leo, Sirius, Canopus and Pleiades. These will be visible toward the eastern portion of the sky during the early morning hours, providing a notable feature of the seasonal transition.

While the arrival of autumn signals the end of the peak summer period, temperatures across the UAE will continue to remain warm to hot during the day. The forecast indicates that daytime temperatures could approach 40°C in several major emirates.

The NCM has also forecast the possibility of convective cloud development over parts of the country. Such clouds may form over eastern and southern areas during the afternoon, resulting in localized changes in weather conditions.

Residents in the eastern and southern parts of the UAE should therefore be prepared for variations in cloud cover as the day progresses. The development of convective clouds is expected to be more noticeable during the afternoon hours.

Humidity is also expected to become more prominent, particularly during the nighttime and early morning periods. Some western parts of the UAE could experience increased humidity overnight and into Thursday morning.

The rise in humidity may contribute to the development of fog or mist in some locations. Visibility could consequently be affected in areas where fog or mist develops, particularly during the late-night and early-morning hours.

The National Centre of Meteorology has issued weather alerts in connection with dense fog affecting parts of the country. Red and yellow alerts have been announced for selected coastal and inland areas, warning residents and motorists about reduced visibility.

According to the weather advisory, horizontal visibility is expected to deteriorate in affected locations through the morning. The reduced visibility is forecast to continue until approximately 8.30am on Wednesday, with conditions potentially becoming more severe at times.

Motorists travelling through areas covered by the fog warnings are advised to remain particularly cautious because sudden reductions in visibility can make driving conditions more challenging. The alerts cover portions of both coastal and internal areas of the UAE.

The weather pattern is expected to vary from one region to another. While much of the country should experience fair to partly cloudy skies, eastern and southern areas may see the formation of convective clouds during the afternoon.

Temperature readings will remain comparatively high despite the official arrival of autumn. Dubai is forecast to record a maximum temperature of around 39°C, while Abu Dhabi could reach approximately 41°C.

In Sharjah, temperatures are expected to climb to around 40°C during the day. The forecast illustrates that the beginning of autumn does not immediately bring a significant drop in daytime temperatures across the UAE.

Nighttime and early morning conditions are expected to be more humid in certain areas. In western parts of the country, this humidity could increase the likelihood of fog or mist formation.

Minimum temperatures are expected to fall to around 31°C in Dubai, 29°C in Abu Dhabi and 27°C in Sharjah. These figures indicate that conditions will remain relatively warm even during the cooler parts of the day.

Winds are expected to remain light to moderate across the UAE. They will generally blow from southeasterly to northeasterly directions and could become fresh at times.

Wind speeds are forecast to range between 10 and 20 kilometres per hour, with gusts potentially reaching approximately 35 kilometres per hour. The occasional strengthening of winds could contribute to changing conditions in exposed areas.

The sea is expected to remain relatively calm, with slight conditions forecast in both the Arabian Gulf and the Oman Sea. No major sea-state disturbance has been indicated in the forecast.

The combination of fair to partly cloudy skies, warm temperatures, humidity and occasional cloud development will shape the UAE’s weather as autumn begins.

The change of season comes after a prolonged period of high summer temperatures. Although autumn has officially arrived according to astronomical calculations, residents should not expect an immediate end to the country’s warm weather.

The astronomical transition is taking place in the early hours of Wednesday, with the official beginning of autumn calculated at 4.05am. At dawn, several notable constellations and stars are expected to be visible toward the eastern sky.

Gemini, Taurus and Leo are among the constellations mentioned in the astronomical observations, while Sirius, Canopus and Pleiades will also appear in the eastern section of the sky during the morning.

The arrival of autumn is one of the key seasonal milestones in the astronomical calendar. However, weather conditions in the UAE generally change gradually, meaning high daytime temperatures can continue well into the early part of the season.

For Wednesday, the NCM’s forecast points to relatively stable weather over much of the country. Fair skies will dominate in many areas, although partly cloudy conditions are possible.

As the afternoon progresses, cloud formations may become more prominent over eastern and southern locations. Convective clouds may develop in these areas, producing localized variations in the weather.

The western parts of the UAE may experience a different pattern, particularly during the night and early morning. Increased humidity is expected, creating favourable conditions for fog or mist in some locations.

The fog warnings issued by the NCM cover selected coastal and internal areas. The red and yellow alerts indicate that visibility could become significantly reduced in the affected zones.

The deterioration in horizontal visibility is expected to continue until 8.30am Wednesday. At certain times, visibility may fall further depending on the intensity and location of the fog.

Drivers are likely to encounter the most challenging conditions during the early morning period, when fog and mist are more likely to form. People travelling during these hours should take the weather conditions into account and exercise additional caution.

The weather alerts are particularly relevant to commuters travelling between coastal and inland areas, where visibility conditions can change over relatively short distances.

Despite the fog warnings, the broader weather picture remains relatively settled. The majority of the UAE is expected to experience fair or partly cloudy conditions, with no widespread severe weather indicated in the forecast.

The country’s eastern and southern regions could see more cloud activity during the afternoon, while western areas may experience increased humidity later in the day and during Thursday morning.

Temperatures will continue to be a key feature of the forecast. Dubai is expected to reach 39°C, while Abu Dhabi could record 41°C, making it the warmest among the three major cities mentioned in the forecast.

Sharjah is expected to see a daytime high of approximately 40°C. Minimum temperatures will be considerably lower but will remain relatively warm, with readings of around 31°C in Dubai, 29°C in Abu Dhabi and 27°C in Sharjah.

The expected temperature range reflects the gradual nature of the seasonal transition in the UAE. While autumn has officially begun, the country continues to experience the residual heat associated with the summer months.

Winds will generally remain from the southeast to northeast and will range from light to moderate. At times, they may strengthen, with maximum speeds reaching around 35 kilometres per hour.

These winds could produce short periods of stronger airflow, although overall wind conditions are expected to remain moderate. Residents should remain aware of localized changes, particularly in areas experiencing increased cloud activity.

Marine conditions are also expected to remain calm. The Arabian Gulf is forecast to experience slight seas, while similar conditions are expected in the Oman Sea.

The relatively calm marine conditions mean that no significant deterioration in sea state is anticipated under the current forecast. However, weather conditions can vary, and residents are advised to follow updates issued by the NCM.

The beginning of autumn also brings a gradual shift in the UAE’s daily weather pattern. Over time, temperatures are expected to moderate as the country moves further away from the hottest period of the year.

For now, however, daytime conditions remain hot. The forecasted highs of 39°C in Dubai, 41°C in Abu Dhabi and 40°C in Sharjah demonstrate that the seasonal change does not immediately translate into cooler daytime weather.

Humidity is likely to be more noticeable during the overnight and morning periods. In some western locations, the combination of humidity and suitable atmospheric conditions could result in fog or mist.

The NCM’s issuance of red and yellow alerts highlights the need for residents to monitor visibility conditions, especially during the early morning commute.

Fog can develop unevenly, with visibility varying significantly between different locations. Areas under the alerts may experience periods when visibility becomes particularly poor before conditions improve later in the morning.

The forecast period therefore combines several weather features: generally fair to partly cloudy skies, afternoon cloud development in the east and south, increased humidity in western areas, and the possibility of fog or mist.

The UAE’s autumn season officially begins at 4.05am on Wednesday, according to the astronomical calculations announced by the relevant official. The event marks an important point in the annual astronomical calendar.

At dawn, observers are expected to see Gemini, Taurus, Leo, Sirius, Canopus and Pleiades toward the eastern part of the sky. The visibility of these celestial objects accompanies the official seasonal transition.

While the astronomical beginning of autumn is precisely defined, the associated weather changes occur gradually. Residents will continue to experience warm conditions, particularly during daylight hours, before temperatures gradually become more moderate later in the season.

The weather outlook for Wednesday consequently reflects a combination of seasonal transition and lingering summer heat. Most areas should remain under fair or partly cloudy skies, while localized cloud formation is possible over eastern and southern areas.

The western region may experience greater humidity during the night and early Thursday morning. This could lead to mist or fog, prompting the weather authorities to issue alerts for affected areas.

The NCM has warned of reduced horizontal visibility in certain coastal and inland locations. The advisory remains in effect through the early morning, with visibility expected to improve after approximately 8.30am.

The red and yellow alerts are intended to draw attention to the possibility of dense fog and significant reductions in visibility. Residents, particularly motorists, should keep track of official updates and take appropriate precautions when travelling through affected areas.

Beyond the visibility concerns, temperatures will remain the main feature of the daytime weather. Abu Dhabi is expected to be the hottest of the three cities, with temperatures reaching approximately 41°C.

Sharjah could see highs of around 40°C, while Dubai is forecast to reach approximately 39°C. Overnight temperatures are expected to drop to 31°C, 29°C and 27°C respectively.

The wind pattern will remain predominantly southeasterly to northeasterly. Speeds are expected to range from 10 to 20 kilometres per hour, occasionally increasing to around 35 kilometres per hour.

Sea conditions are expected to remain slight in both the Arabian Gulf and the Oman Sea, indicating generally calm marine conditions under the current forecast.

As the UAE enters autumn, residents can expect the country’s weather to gradually evolve in the coming weeks. For Wednesday, however, warm daytime temperatures, localized cloud formation, humidity and early-morning fog remain the principal features of the forecast.

The NCM’s latest outlook therefore calls for generally fair to partly cloudy weather across the country, with localized cloud development in eastern and southern areas during the afternoon.

At the same time, increased humidity in western locations could lead to fog or mist during the night and Thursday morning. The associated red and yellow alerts serve as a reminder that visibility conditions may deteriorate rapidly in affected areas.

With autumn officially beginning at 4.05am on Wednesday, the UAE enters a new astronomical season while continuing to experience relatively high temperatures. The gradual seasonal transition is expected to bring changing weather patterns over time, but hot daytime conditions will remain for now.

Residents can expect a mix of sunshine, partial cloud cover, humidity and localized fog as the country moves into the new season. The NCM will continue to monitor conditions and issue relevant advisories where necessary.

For the latest information, motorists and residents should pay attention to official weather updates, particularly before travelling during the early morning hours when fog and reduced visibility are most likely to affect roads in some parts of the UAE.
