Hello Adventurers!

I'm here with a question about our travels during the rainy season. The plan is to travel from half september till about half january though CA. We'll land at Panama first, and the plan was to go up to Costa Rica, Nicaragua, Guatemala and end in Belize.

Roughly initerary would be about 3 weeks each, maybe some days extra here and there, and the rest in Belize
Panama:19th - half oct
Costa Rica - Half Oct - beginning nov
Nicaragua - Beginning Nov - end of nov
Guatemala - December -
Belize - January

Now I read pretty much everywhere that especially Oct is a bad month to travel to CA, due to the high amount of rain. Now I'm just wondering if I should adapt my plans to this (maybe go to another country for a month/couple weeks?)
Yes there will be rain, and I don't mind a shower here and there, but continuous rain to drown our adventures would be sad ofcourse. So I'm just curious about experiences during that time!

Thanks in Advance!
