Weather in Dubai in August
United Arab Emirates · 20-year averages, August
The month to avoid. August is the month most people should skip in Dubai. Daytime highs average 39.7 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.
August ranks 11 of 12 — near the bottom of Dubai's year. February is the month that works, and the swing between the two is 68 points, which is a different holiday rather than a slightly better one.
Rain is not a factor worth planning around this month. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.
What the averages hide
Averages flatten a month, and this one hides a few things: 31 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest August day reached 44.3 °C and the coldest night fell to 29.4 °C.
August is dependably dry, and that reliability is the point: across the twenty years measured, the wettest August on record still only managed 5 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Augusts brought 3 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.
Wind is light at 10.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 52%.
How August sits in the year
Temperatures hold steady either side: 39.3 °C in July, 39.7 here, 37.7 in September. Nothing about the timing within the month matters much.
Daylight in August
13 hours of daylight, losing 0.6 hours across the month. That is between Dubai's extremes of 13.7 and 10.6 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 33.7 °C in August — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
August in Dubai versus nearby
If Dubai is one option among several, the nearby comparison is worth making. Al Ain City is close enough to be a coin toss — 4.8 °C warmer, 1 day more rain. Rājkot is a better bet in August — 8.3 °C cooler, 16 days more rain.
So: August is a compromise. February is 68 points better and is what Dubai is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
