The Weather on Tenerife changes considerably depending on your location.
The warmest climate can be found on the south and west sides of the island. But, if you go near El Teide, cold winds and snow wouldn't be hard to find.
Tenerife features the lowest temperature 'difference' between summer and winter for anywhere in the world. Our weather occasionally includes rain, but there is no specific 'rainy season'. Air conditioning is quite rare, with overhead fans usually providing sufficient air movement to stay cool, even at the height of summer. The minimum and maximum annual average air temperatures in Tenerife are about 15C in winter and 24C in summer. Therefore we enjoy wonderful weather in one of the world's best and most delightful climates. The Island offers a surprising variety of micro-climatic weather zones, enabling people to almost 'choose' their climate, depending on where they live.
The Trade winds, together with the refreshing Gulf air currents, are the major weather factors that contribute to Tenerife's climate. The great altitude of Mount Teide gets up to three months of snow - yet it is still possible to enjoy a swim on the beach within an hour's ride. The coastal areas enjoy the most sunshine, the best weather, the least clouds and highest temperatures.
