NO it isn't true!!!! If we are going to have rain anywhere on the island, including a 2 minutes thunderstorm then you will see rain predicted!!!!
I do the weather report here, check out hte thread. We have been having stunning weather here on the north coast! Bring an umbrella and good shoes as we will likely have isolated storms but mostly you will find it very hot and sunny!
Enjoy. Anything else you want to know???
