You could say "the good weather made us happy." :-) You would also say "the good weather put us in a good mood." Or "the good weather put us in a good frame of mind." You can also use different words than "good." "The lovely weather put us in a good mood." "The warm weather put us in a good mood." Etc.

"brought us good mood" sounds a bit clunky to me. Here are some alternatives: - The good weather brightened our mood. - The fine weather lightened/cheered us up. - The sun made our day brighter.

It's already natural, but you can also say: The sun cheered us up !

Good weather made me turn on. lol
