Tenerife is often referred to the “island of eternal spring”. This stunningly beautiful paradise island typically brings lots of sunshine, beautiful blue skies and pleasing warm temperatures for most of the year. There is usually more sunny days than rainy days, but the uneven terrain and mountains do help to create a diverse climate even among various cities and regions. Grouped together are diverse locations like ParqueNacional del Teide and its pine forests with volcanic landscapes of Teide and Malpais de Güímar. There are some areas that are practically deserts complete with droughts and plants that grow in drought, and then other areas that practically surround visitors with mountains. There are also valleys and forests that have subtropical vegetation.
While warm climate dominates the year, there is a cooler winter season and temperatures can drop down to 13–18 °C. However, by summer, the temperature rises to 24–28 °C and the climate provides plenty of sunlight, necessitating hats, sun block, sunglasses and light coloured clothing to make the day more comfortable. Unlike other tropical or desert destinations, the average temperature for Tenerife is moderate, and much of the weather is dominated by tradewinds that bring humidity to the north of the island. This creates cloud blanks that can rise up to 1800 metres. Another impacting force is the current of the Canary Islands, which is cold and succeeds in cooling coastal temperatures.
Bizarrely, if you were to drive through the entire island you might see some highly contrasting temperatures, with winter snow within a few kilometres from the warm and tropical coast. The lower the altitude the more drastic the climate changes. Santa Cruz de Tenerife tends to be arid, compared to Buena Visa del Norte in the North-western area.
The North-western part of the island does receive 73 percent of precipitation that comes to the island. The La Orotava mountain range tends to have high altitudes of 1,200 metres. Even so, comparatively, the yearly precipitation is low and for the most part your summer stay (the ideal time) in Tenerife will be dry. Rainfall is unpredictable but this is hardly a flooding or heavy rain scenario.
Although there is snow on the mountain tops the combination of trade winds and sea breezes help to make the summers warm not hot, and the winters very cool but not freezing. It is an ideal region for calm and relaxing weather. For the most part, expect to encounter sunny days of 17 º C (63 º F) and 21º C (70º F). You might want to remember that booking during the winter months or off season, while not as warm, might bring a discount from summer prices.
Tenerife is known to have one of the best climates in the world and the locals will tell you that the best time to visit is in August through October. Some evenings can be chilly to come prepared with a jacket, sweater or coat.
