The weather on La Palma is like springtime all year long….. 
The yearly average temperature is around 20°C and 22°C.
In summertime it’s very rarely more than 30°C, and in wintertime it’s very rarely less than 15°.
The highest temperature at the airport of La Palma was…. 38°C
But of course, if I tell you, that here the weather is mostly like springtime, that doesn’t mean that there are no seasons on La Palma. Here we have winter and we have summer….. but it doesn’t make a big different…. In winter there are more rainy-days and more cloudy-days… that’s it!
