i know this has probably been discussed before but i couldn't find anything.

I am planning on taking the family away the Mid of June and just so happens I want to make sure we go somewhere there is surf. Looking closely at Guanacasta area, Playa negra through Papagayo region. i know the surf could be big i am just concerned about the rain. Does it rain everyday? are we going to be stuck in the hotel every afternoon.?

Any other suggestions for good surf, warm, and family friendly for June?
