nice and easy site, but 10 day forecast only.

Anybody knows any site with long range weather forecast for hawaii? Like 30 days or more?

I don't think there's any one site that can give you a 30 day forecast for any destination, is there? That would be irresponsible, IMHO....weather changes so quickly. but you can check the history of weather in an area using www.wunderground.com

To a meteorologist, ten days is guesswork. They will hang their hats on 48 hours, but anything longer than that is chancy. Thirty days is impossible, except for "if it is summer, expect warm temperatures; if it is winter, expect cooler temperatures."

Especially difficult, here in Hawai`i.

Morning weather broadcast can say "rain", and none comes. Evening weather broadcaster that night will say "Surprise, we got a wind shift that took the predicted rain elsewhere"!! )

Wanna know what the weather is? Step outside. Don't like what you see or feel? Drive to the other side of the island.

Auntie, not even that far! I think you can easily drive 5 miles in any direction (on almost any island) to find different weather. frenchme, Hawaii is known for its microclimates.

What do you mean it isn't possible to do a 30 day weather forecast for Hawaii? The forecast for 30 days from now is "sunny, highs 80 to 85, with a small chance of rain."

Wait 30 days and see if that forecast isn't accurate.

i know one website it gives 6 month forecast... (dryday)
then why 30 day is not possible?
