As a local I can tell you that the forecasts are not accurate until an hour away, and not even then sometimes...100% chance today and we have only seen a little shower for about 30 min, other days can be zero chance and pour. My advice is pack a poncho, and sunscreen, plan for rain, but you never know what will happen.
We leave on 4/16 for five nights. The weather is not looking too good for those days at the moment. How accurate do you think the forecast is this many days out?
