UAE Braces for September's Heat and Humidity

Heat and Humidity: UAE's Weather Mid-September

For the residents of the United Arab Emirates, mid-September marks a special period: the official beginning of the seasonal transition. On September 6, the Safriya season began, signaling the end of summer and the gradual arrival of winter. Traditionally, this period involves a slow decrease in temperatures, but in 2025 this change is still delayed – at least from a weather perspective.

According to the latest forecast from the National Centre of Meteorology (NCM), hot weather is expected in the coming days, especially in the Abu Dhabi and Dubai regions. Daytime maximum temperatures may reach 41°C in Abu Dhabi, while peaks of 40°C are predicted for Dubai. Although summer has officially ended, the weather still resembles the hot months.

September 13: Sunny, Slightly Cloudy Weekend Anticipated

During the weekend, especially on September 13, most of the country will experience clear or slightly cloudy weather. However, in the eastern regions, cloud formation is expected in the afternoon, which can sometimes become convective – meaning the combination of elevated humidity and temperature can lead to local cloudbursts, even showers, particularly around the mountainous areas.

Such convective clouds are common in the eastern parts of the UAE, especially near the Hajar Mountains. Although these generally last only a short time, it is important for locals and hikers to be prepared for these rapidly changing weather phenomena.

Evening and Early Morning Humidity: Uncomfortable Comfort Levels

After the daytime heat, temperatures begin to drop, but during the evening and early hours, high humidity makes comfortable rest difficult. According to the NCM, the western regions may particularly experience significant increases in air moisture, leading to condensation and even fog patches.

This phenomenon is especially important regarding transportation, as visibility may decrease in the early hours. Drivers should exercise increased caution, particularly on the western sections of the Dubai–Abu Dhabi highway.

Sea Conditions: Calm, but Caution Advised

Sea conditions will generally be mild or moderate in both the Arabian Gulf and the Sea of Oman regions. However, on Sunday morning, rougher waves might occur temporarily in the Arabian Gulf, especially near the western coastline. Sailors and fishermen are therefore advised to pay attention to meteorological alerts and to proceed with caution when setting sail.

The Significance of the Safriya Season

In the Emirates, the Safriya season is not only important from a meteorological perspective but also holds cultural and traditional significance. According to Bedouin traditions, this period was an important phase of desert life when the heat began to subside, but the real winter had not yet arrived.

Today, the beginning of Safriya has particular significance for agricultural communities, gardeners, as well as those who enjoy outdoor activities. This period indicates the approaching cooler season, which is suitable for hiking and outdoor sports.

What Should Residents Pay Attention to in the Coming Days?

1. Hydration: The combination of high temperature and humidity results in increased fluid loss. It is important to ensure adequate water consumption.

2. Sun Protection: During midday, UV radiation can be particularly strong, so it is advisable to use umbrellas, hats, sunglasses, and high-factor sunscreen.

3. Limiting Outdoor Activities: If possible, schedule outdoor activities in the morning or evening hours, avoiding the midday heat.

4. Vehicle Use: Heat trapped in cars can rise extremely quickly – never leave children or pets in a parked vehicle!

5. Optimizing Air Conditioning: Alongside continuous air conditioning use, ensure room ventilation to avoid the discomfort caused by excessively dry air.

Patience Required During Seasonal Transition

While many are already waiting for cooler weather, due to the unique climatic conditions of the UAE, real relief usually arrives only by late October or early November. Until then, the gradual transition continues, with nights becoming fresher but days still reminiscent of summer heat.

The meteorological center continuously monitors weather changes, keeping residents and tourists informed about potential heat waves, rising humidity, or sea storms.

Summary

During the second week of September, the UAE is still experiencing the after-effects of summer heat, despite the Safriya season having started. In the Dubai and Abu Dhabi areas, temperatures can reach 40–41°C during the day, while nighttime humidity makes resting difficult. The sea is relatively calm, but rougher waves could develop in some places by Sunday morning. Residents and visitors are advised to follow weather forecasts and adapt to current conditions – especially when planning outdoor activities.

In the coming weeks, temperatures are expected to gradually decrease, creating ideal conditions for outdoor activities for which the Emirates are famous. Meanwhile, it's worth enjoying the sunshine – but always in moderation.
