There is some Thunder around right now. And patches of rain.
I am going to say the 2022 Rainy season started on Monday 24 May
The Rainy season start is loosely defined as :
" Over 30mm ( 1ï¿½") Rain in a Week, and 5 of the next 7 days are significant rain days. "
On Monday we had 25mm ( 1" ) of rain over night.
Belmopan may not have had much rain until today, but many other parts of Belize have had a lot of rain.
And the forecast is for significant rain over the next 4 or 5 days.
So I feel we can say we are now in the Rainy season, even though we could easily have a fair bit of dry in early June.
