Can you please help, I need to make cookies for church bbq; but it's warm and humid.

Can anyone help me please, I am going to be doing as many kinds of cookies as possible for neighbourhood barbecue planned for next Sunday after church; but it's been hot and humid here, which doesn't help when trying to bake?
I have a few no bake varieties picked out; but any suggestions would be greatly appreciated.
Thank you in advance.
