Im off to Krabi in early June. Can I still do the island hopping tours and snorkelling despite the rain?!?

I'm really hoping that the monsoon doesnt play spoilsport on my trip to Krabi. I'm staying in Au Nang beach so that I have access to other activities. What im dying to do is to see the beautiful small islands around Krabi including that of Phi Phi and I want to know if thats possible in early June. Just worried if the rainy season puts an end to those sight-seeing options. Someone help me (give me good news)!!
