The sun shines somewhere on La Palma almost every day of the year. This is the land of eternal spring. The Canary current and the trade winds have a moderating effect on the African desert climate. Temperatures barely drop below 18 degrees in winter and rise to a good 25 degrees in summer. The Cumbre acts as a weather divide . It constitutes a natural barrier to the constant northeast trade winds; the trees milk the sea of cloud so formed and above it the sky is a clear, dark blue.
The island only gets hot and dry with winds from the south or east (calima) when Sahara sand covers everything.
Two or three time every winter an Atlantic trough sweeps across the island from the west, bringing heavy rainfall.
