First of all, thank you all for the great information, it's been very helpful in planning my first trip to Big Island.
I'll be spending a long Thanksgiving weekend at Mauna Lani Resort and most likely explore only the west coast part of the Island. I'm planning to do some snorkling (very novice level), relax by beautiful beaches, and hike along the coastal area. This is my first time visiting Hawaii in winter time (?) and I am not sure what to pack. I have been tracking the weather and it'll be low 80s daytime and low 70s at night. I also see some shower in the forecast. But I'm not sure whether those temperatures feel the same as here in CA.
So, for this trip, will I need long sleeve shirts, pants, or sweaters for the most part of the trip? Or will it be comfortable weather for shorts, t-shirts, and bikini (and just a sweater for night)?
Thank you, I really appreciate your input.
