Arrh Rothers. It is a bit disheartening to think it might rain whilst on holiday, but I'm sure the weather will be O.K for you. The only time it has rained for us in Arillas has been very early in the season - beginning of May & that was for just a couple of days. Now last winter, in February was a different story. I've never seen rain like it!
If you do experience a thunderstorm, they don't last long & if they occur at night, they are actually quite spectacular.
Last year we visited Arillas for the last two weeks of October which can be a bit unpredictable, but we had two weeks of fantastic, unbroken sunshine. You just never know.
Whatever the weather, you are sure to have a great time in Arillas.
Wishing you lots of blue skies & sunshine.
