When you get to Tenerife, you will discover a place where spring never ends. The Island boasts an average temperature of 23 ºC (73.4 ºF) and is blessed with roughly 300 days of sunshine. That is why you should not forget your sun cream and beach wear. And if you are coming in summer, we recommend you bring comfortable cotton clothing. When visiting in winter, pack at least one jumper or jacket and always keep in mind the altitude of the area you are going to as the temperature varies.
The influence of the trade winds and the Island’s mountains create a mild microclimate. You will notice that at times the temperatures can change in a matter of just a few miles, which is definitely something for you to bear in mind when exploring the Island.
