I've also read that Haleakala can get down to freezing and below at sunrise but also once the sun has risen its really strong because of the high altitude so if like me you burn easily don't forget the suncream. I'll probably borrow my boyfriend's hoody and wear that over a cardy and tshirt with my light jacket. Then I can just take if off as we go back down the mountain.
I found this website pretty good for an idea of what the weather should be like:
San Diego October weather
Honolulu October weather
So early 20Cs for the west coast then about 30C for Hawaii.
I'll probably stick with jeans and tshirt for west coast, then for Hawaii I picked up some shorts and summer dresses in the sale. From what I've read Hawaii is really relaxed so you probably won't need anything too smart even for dinner, but then I don't really do posh dining anyway 🙂 Also even though it says on our info sheet to take mosquito spray I was talking to my boss at work whos been and she said its not needed, specially by the sea and everything I've read online said its not really needed unless you're prone to bites so I don't think I'll bother. One thing that's definatly on my list though is my bug catcher, I hate creepy crawlies in my room!
Has anyone got an idea of how much spending money they'll be taking? I was thinking about $1000 cash then will get a credit card with no international fees and just put as much on that as I can when I buy things. I don't really drink alot so mostly will be just spending on food and a couple of souvenirs.
Looking forward to meeting you all in a couple of months!
