Dubai: The official start of the summer will fall on June 21 and with it temperatures are expected to become slightly higher by one to two degrees Celsius in the UAE.

The summer solstice in the UAE falls on Friday at 7.54pm, which is when the sun’s rays fall perpendicularly on the earth’s Tropic of Cancer at 23.5 degrees north latitude.

In terms of daylight, this means that June 21 is also the longest day of the year and three hours, nine minutes longer than the winter solstice. On the shortest day of the year, the sun rises at 5.29 am and sets at 7.11 pm.

What is a solstice?

The word solstice is derived from two Latin words: sol (sun) and sistere (to be still). A solstice can be defined as an event when the sun is at its highest or lowest point in the sky. This happens twice a year, and the occurrence of the summer and winter solstices marks the longest and shortest two days of the year, respectively.

Record temperatures

The weather on Wednesday and Thursday will be partly hazy and cloudy, especially over eastern areas by the afternoon. Moderate to strong northwesterly winds will cause dust and sand to blow over exposed areas, with a speed of 20 to 30 km/h, reaching 50 km/h at times. Temperatures will slightly drop by a couple of degrees before rising once again at the end of the week.

The sea will be rough in the Arabian Gulf and moderate to rough at times in the Oman Sea.
