Need ceiling fan advice

Hello, all y’all smart and handy folks!

I have a 16x18 room with a 2x3 skylight in the center. That leaves two 16x7.5 sections of ceiling to put ceiling fans on.

Will two 30” fans be enough in the hot/humid Texas summers?

NOTE: It is imperative that the blades stay out from under the skylight to avoid creating a strobe effect. Too many people in this household get migraines and that frequently triggers them.
