I am also going in October (a few days before you) so I hope it's going to be hot. Looking at average temperatures it should be like going in May and when I have been in May it's been fine. I am expecting to sunbathe and walk around in shorts and t-shirt. Nights might be a bit cooler but if you're from Scotland it'll feel warmer than usual.

There may be an overcast day or a bit of rain even, but generally it should be hot and sunny.

Playa Blanca is lovely by the way, can't wait to walk along the front.

I am staying at the Papagayo so if you are too, make sure you say hello.
