Tenerife North is much quieter largely because of its cooler, wetter weather, especially in the winter months. Summers on the north coast are still hot but are a little more overcast with slightly higher rainfall levels. Tourism is still a high earner for the north but thinner crowds mean that many areas remain unspoilt. Resorts on the north coast include Puerto de la Cruz, El Sauzal, and Garachico. The area is popular with walkers and golfers. The wetter weather has resulted in a more verdant landscape where palm trees and banana plantations thrive. The beaches on this side of the island are mostly black, volcanic sand.

Summer

From June until September, is very similar to that in the south but a few degrees cooler. It sees average high temperatures peaking in August at 29°C. Sunshine levels are also at their highest in July with 13 hours per day. As in the south, rainfall is almost non-existent as it tends to fall in the higher, central mountains of Tenerife. The region can be quite windy so conditions can be changeable. This keeps temperatures in check and also gives rise to great watersport conditions. Windsurfers and sailors seek out the strong trade winds. The north is generally safe from the sirocco wind.

Autumn

In October and November, is pleasantly warm, much like winter in the south. 21-23°C can be expected in the day but night times are cooler around 18-20°C. The sea remains warm enough for swimming and sunshine levels are very reasonable at eight hours per day. A few storms may blow in but infrequently. October sees rain on around five days and showers are usually heavy but short, and followed by clear weather.

Winter

From December until February, is slightly cooler and a wetter than on the south coast. The average high in January is still 20°C with an average low down to 15°C. This is hardly cold and many like to visit the area for walking holidays during this season. The sea generally does not fall below 15°C. Sunshine levels remain good at around seven to eight hours per day throughout the season. Rain is still not frequent at all but when it falls it can be heavy. If you’re lucky you’ll miss the rain altogether.

Spring

From March till May, is very mild and gets warm by the end of the season. The average high rises slightly to a pleasant 22°C in March and April and up to 23°C in May. Night times remain cooler. The sea heats up very slightly to 18°C in May. Again, this is a popular time to visit for a more active holiday. Spring is a good time to visit if you don’t want to spend all of your time on the beach and you don’t like competing with crowds.
