Though the peruvian coast is famous for being cloudy, this is more frequent in Lima, though this summer we are enjoying several sunny days. The Dakar started in a shiny sunny morning, for example.

But I'd say clouds are less often in the rest of the coast. And there are several alternatives to enjoy. Of course northern Peru brings the best offer, but there are lot of beautiful landscapes in Ica (Paracas), Arequipa and all coast regions, too. Just wanted to share this info, you may find it useful.
