The average maximum daytime temperature in Dubai in September is a very hot 38Â°C (100Â°F), while the average minimum night-time temperature is a warm 26Â°C (79Â°F). On average 0 mm (0 inches) of rain normally falls in Dubai during September with very little chance of rain falling during the month.
September weather is generally great. Low humidity, temps in the 60's during the day, 40's at night, and not that rainy. However, once in a while you can also get: daytime temps in the 30's or 40's with snow showers, or daytime temps around 90, so come prepared either way.
