When Does Summer End? Expert Insights

When Does Summer End? Expert Forecasts for the Coming Weeks

In the United Arab Emirates, August 10 marks the traditional end of the Al Mirzam period, characterized by hot, dry winds and intense heat. Historically, this date symbolized the closure of the toughest part of summer, yet due to climate change, past weather patterns are not always reliable.

Temperature Changes and Wind Patterns

According to forecasts, significant cooling is still awaited. The National Centre of Meteorology expert suggests that a gradual change may begin at the start of September, primarily with a moderate decrease in nighttime temperatures. Daily wind direction shifts directly influence the perceived heat:

Morning (land breeze) – Cooler air flows from land to sea, bringing relief.

Afternoon (sea breeze) – Warmer, more humid air flows from sea to land, increasing the heat.

Occasionally, cumulus clouds may form, which, along with downdrafts, can bring fresh, stronger winds and create dusty conditions. In the coming days, coastal areas can expect peak temperatures between 39–44 °C, while inland areas may reach 44–47 °C.

Astronomical and Cultural Time Indicators

The Marhiyat al-Qala’id season, known as the "loosening of necklaces," once indicated that desert-dwelling communities could tie their camels at night due to milder temperatures. Another traditional indicator is the appearance of the Suhail (Canopus) star around August 24-25, marking the gradual cooling of desert nights.

While these signs remain culturally significant, modern meteorology and the impacts of climate change render them less accurate for weather forecasting. Average temperatures in parts of the UAE have risen by approximately 2.7 °C since the 1970s, and the transitions between seasons are less predictable.

When to Expect Genuine Cooling?

Experience suggests that temperatures noticeably begin to decrease only between late September and October when daytime highs drop to the mid-thirties range. In Dubai, the hot season typically lasts from mid-May to late September, with the cooler period beginning in early December.

In Summary

Although the end of the Al Mirzam period traditionally brings hope for heat relief, high temperatures are expected to continue in the coming weeks. More sustained cooling is only anticipated in early autumn, with winds and clouds providing temporary respite.
