Weather details in may
The month of May is favored by a more remarkable rise in temperatures. Climatic conditions are improving gradually and it is now possible to have more sunny days during the month. As it is still cold, one must think about wearing comfortable clothes. The climate throughout May in Iceland is still unfavorable because of the persistent cold. Neither the frigid rains nor the snowfall have completely disappeared.
May in Reykjavik and South-western Iceland
The few sunny days during the first period of May indicates a marked improvement in climatic conditions. This is especially true as the temperatures are increasing and favor a relatively gentle atmosphere. On the other hand in mid-May, the rains begin to fall sporadically and towards the end of the month, wearing waterproof clothing is a must. The south of the country is experiencing a resurgence of rain and because of the wind speed that is quite strong, umbrellas are not really the best solution.
May in Akureyri and Northern Iceland
Expect snowfall during the first days of May in the north of the country. In fact, the temperatures are still cold, especially in the mornings. However, the weather in Iceland throughout May is gradually improving. One can then bet on beautiful sunny days towards the end of the month for their outings.
