Tenerife weather in May
By May the weather in Tenerife becomes really predictable with the south of the island generally enjoying hot and sunny weather and the north also being warm and sunny but with more cloudy spells and still a possibility of rain during the month; although the difference in temperatures isn’t significant.
Daytime shade temperatures range from 24-26C in Tenerife south and 23-25C in Tenerife north.
