Hunting in the rain has advantages. Ground cover is quieter for stalking, animals don't hear as well, and rain usually knocks down scent. The animals don't move around much so if you know approximately where they are, you may be able to catch them in their beds. If the weather breaks and sun pops out, you have a good chance of spotting them standing in the open to dry out. In Africa the best conditions for kudu hunting were a night of drizzle or fog that let up just before dawn. Look for them at daybreak in small openings trying to warm up in the sun.
