Being contrary
This is contrary to XR's statement, with all the due respect to him but there is a rainy season in Punta Cana and May is it. Evidence of this is that PJT had to seal the roof of his house with a membrane to correct rain water penetration through the cement roof that was ruining the ceilings. Always happened in May and November.
But, do not despair, there is more sun than there is rain.

PJT
