How warm is it in Iran during May?

The temperature reaches around 26℃ during the daytime in May, falling away to 16℃ at night. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in Iran during May?

On average, there will be 2 rainy days during the month, amounting to 23.8mm in total. That's much drier than we see in England during August, and therefore not something to be concerned about. There's a small chance that you'll catch a thunderstorm during your trip.
