From May until sometime in December rain is a common ocurrence in Panama. We are blessed with rain for 8 months and that's why the Panama Canal is here.
When is it going to rain?
No one can answer that question and the weather forecast you are looking at, it's wrong. It doesn't rain everyday and it doesn't rain all day long. If it does, enjoy it!
Please stop checking the weather forecast and simply go with the flow!.
I am not a weather expert or meteorologist or a witch so I can only wait until the day of the tour comes and take it from there. Life is that simple on this side of the world. We have other things to worry about like, what flavor of popsicle we will be trying today!
If you have a tour planned, just relax, there are 2 things no one has control over: weather and traffic.
If you ask me how the weather would be, my answer ALWAYS would be exactly the same: I don't know.
I understand you want me to have a more specific answer but I don't have it and I never will.
My advise to you is: Stop worrying about small stuff, let the day come and make the best out of it.The good news is that we tour with rain or sun and always have lots of fun! Guaranteed.
