Hugo,
Bon dia and welcome on the forum.
I agree with the foregoing reactions regarding taking the second flight.
KLM is normally very punctual and I have not experienced delays of more than 15 minutes, but it's too tricky.
When it's crowded in the air .............you simply have to accept these delays these years
November is a good time. Don't worry about your timing.
It's formally the last months of the rainy season, but even now it is not raining a lot. Luckily it did rain today !!!
It had been many days without rain here at my place.
