Thor.
There’s a reason he’s worshiped as a fertility symbol as well as a warrior and protector, and that’s because he brings the rain that nourishes crops.

Really?
Total UPG here, but I always associated him with the noisy bits of the weather/stormy season, and Freyr with the actual rainfall.
I have seen many mentions tying Freyr to rain as well, and it does make sense given his place as a fertility god.
I can see that, though. I tend to associate Thor with the big crashing booming start of a storm, and I can sense Freyr in the more gentle steady rain that settles in for a good long soak.
