The city ranks among the hottest populated areas in the world, and even if you study the weather in Dubai for 3 days during the winter months, you'll rarely see the thermometer drop below +15-20°C. And +10°C and below is considered an abnormally low temperature for the area.
Extremes who have been here in the summer will confirm: during this period, the weather in Dubai for all 14 days can "please" 50-degree heat with 90% humidity. Air conditioners are running everywhere, even at the stops of public transportation, but it is still too hot for this time of year.
From November to Marchthis is the most comfortable weather in our understanding, and in Dubai for a week or two come most often in this period. Rather high humidity remains, but there is no heat.
If you are not afraid of heavy rains with thunderstorms, go here in spring or fall. Precipitation is not very frequent at this time, but sometimes, when you study the weather in Dubai for 5 days, you'll find that forecasters promise prolonged rain. This can cause serious traffic jams in the city, so keep this in mind when planning your itinerary.
