I think that if we build a lip around the skylights and seal (Caulk) them properly, we can keep rain from entering the coop through the sky lights.
Why do you want the skylights?
The wire wall and the vents on the other walls will allow sufficient light into the coop and shade is your #2 critical need to protect against overheating after ventilation.
It doesn't really need to stay completely dry. You probably see many places saying how important it is that they stay dry and I agree - for cold climates. I assume your monsoon season is not while it is near freezing or below
I agree -- unless the coop is so small that the rain blows from side to side, leaving no protected area -- it's not necessary to worry about a little rain along the sides of an Open Air coop in a warm climate.
It rains in about 3 feet along the sides of Camp Cockerel but dries out rapidly and in Neuchickenstein (the coop featured in the hot climate article), the occasional storm that manages to penetrate the roof overhangs serves only to provide needed moisture to the deep litter so that it will compost in place properly.
The enclosed coops, The Little Monitor Coop and the Outdoor Brooder, need to be kept dry, but for the open ones a little moisture now and then is part of the system.
