The best time to visit is between October and April. The city is really home to just one season unless of course, you look at hot and hotter as two separate seasons. There is, of course, a 'winter season'; this falls between the months of October and April, and 'no' there is no snowfall. The season is so named due to the cooler winds and perfect sunny skies beach weather that prevails. The 'winter season' is also the rainy season in Dubai, but you will only experience mild showers and it rarely rains the entire day.
