We went the third week of February, and I'd be surprised if it ever reached 48 degrees then. However, one year we went the very beginning of March and it was in the 70's every day and only rained a little on the first day. The week after we left, I heard it rained all week. So who knows! But what's nice if the weather is cold is the daily hot cider and cookies in Big Murgie's Den. Makes going then worthwhile. As long as it doesn't rain, I think you'll be able to go outside. But don't take that Dolphin Cruise then-it gets really COLD out there on the water!
