Dubai Weather Alert: Temperatures Could Reach 42°C on September 5
Dubai, UAE — September 5, 2026: Dubai is set to experience another very hot day on Saturday, with the National Centre of Meteorology (NCM) forecasting temperatures of up to 42°C in the emirate. The weather is expected to remain generally fair to partly cloudy, while some parts of the UAE could see clouds developing in the eastern areas during the afternoon, bringing a possibility of rainfall.
According to the latest UAE weather bulletin reported by the Emirates News Agency (WAM) and Khaleej Times, temperatures across the country are expected to gradually increase on Saturday. In Dubai and Abu Dhabi, the maximum temperature is forecast to reach 42°C, while Sharjah could be even hotter, with temperatures reaching approximately 44°C. The minimum temperature is expected to be around 33°C in Dubai, meaning residents may continue to experience warm conditions even after sunset.
Hot and Humid Conditions
The high temperature is not the only factor residents need to consider. Humidity is expected to increase during the night and into Sunday morning, particularly around coastal areas. Higher humidity can make the weather feel considerably hotter than the actual temperature because the body has more difficulty cooling itself through evaporation.
Other forecasting services are also predicting very hot conditions in Dubai on September 5. The UK Met Office, for example, forecasts a maximum of around 40°C for Dubai, with a minimum near 31°C and sunny conditions during the day.
Because different forecasting models can produce slightly different temperature estimates, the official NCM forecast of 42°C for Dubai is the most useful figure for residents planning their Saturday activities.
Possibility of Rain in Some Areas
Despite the intense heat, the UAE could see some cloud development during the afternoon. The NCM says convective clouds may form toward the eastern parts of the country and could be accompanied by rainfall.
However, this does not mean that widespread rain is expected across Dubai. The possibility is mainly associated with eastern areas where convective clouds may develop. Residents should therefore not expect the temperature to fall significantly simply because clouds appear.
Some weather services are forecasting mostly sunny or clear conditions for Dubai itself, reinforcing the expectation that much of the city will remain hot and dry.
Winds Could Become Stronger
Winds on Saturday are expected to be generally light to moderate, but they may become fresh at times, particularly around areas where clouds develop. The NCM forecast puts wind speeds at approximately 10–25 km/h, with gusts potentially reaching 40 km/h.
Stronger winds can create blowing dust or reduce visibility in some areas, although the current forecast does not indicate a major dust storm affecting Dubai.
For people travelling around the city, particularly those using motorcycles, bicycles or walking for long distances, it would be sensible to remain alert to changing conditions.
Advice for Dubai Residents
With temperatures around 40°C or above, residents should take precautions when spending extended periods outdoors. People working outside, exercising, walking between metro stations and offices, or travelling around the city should carry sufficient water and avoid unnecessary exposure during the hottest part of the afternoon.
The heat can be particularly challenging for people who are not accustomed to Dubai’s summer climate. Even relatively short periods outdoors can lead to dehydration when temperatures are high.
People should also be careful when entering or leaving air-conditioned buildings. The sudden transition between heavily air-conditioned indoor environments and extreme outdoor heat can feel uncomfortable.
What to Expect on Saturday
For Dubai, Saturday is expected to remain very hot and predominantly sunny, with temperatures around the 40–42°C range depending on the forecast source and exact location. The official NCM forecast gives a high of 42°C, while other meteorological services put the maximum closer to 40°C.
The weather is expected to remain warm overnight as well. Dubai’s minimum temperature is forecast at approximately 33°C, meaning residents should not expect particularly cool conditions after sunset.
Overall, September 5 will be another extremely hot day in Dubai, with high temperatures, possible humidity and limited relief from the heat. Residents planning outdoor activities should preferably schedule them during the early morning or later evening and keep hydrated throughout the day.
