Take a raincoat/umbrella. I have a season pass and it stays open pretty much all the time except for past covid restrictions. I went there last week mid May when it was rainy, birds came out but some of the animals might be inside. Go through the wildlife enclosures built to view them if so.
Again, take an umbrella.it rained, there were T-storm warnings, but they didn't close
They will most likely be open. It will be spotty. Take an umbrella
