no one will know if there is wind. Depends on the rain. Might be dry, might rain. Hit or miss.
But if dry, you will have wind for sure.
14-40 knots sounds fine...I assume you will find max 30 knots, so 10-30 is most likely.
Cumbuco like 10-25.
You can rent a car, but you can only drive until Prea if no 4x4...Jeri has no access street...
There are people doing transports...along the beach...very nice trip. Not cheap though...but an adventure for sure.
thank you Toby
