Hi, all! Quick question: could someone please define "cold" or "cool" as it relates to Volcanoes National Park on the Big Island? I keep hearing references to it being "cool" at night but am not finding actual evening temperatures or more specific details. Mind you, I'm not worried about "getting cold" as I now live in the DC area and have had my share of cold weather, snow, and blizzards here (and my boyfriend is from New England so he's even more used to it). My concern is that I don't want to pack cold-weather clothes that I might not even need.

Our plan is to arrive in Hilo in the AM and do some of the stuff around there (Akaka Falls and such) and arrive at Volcanoes Nat. Park just before dusk to watch the lava flow in the early evening and then immediately go to our hotel. I'm thinking some lightweight pants, good sneakers with socks, and maybe a long-sleeve shirt will do the trick. Or do I need something else? We won't be outdoors for all that long, and to me it's not "cold" until it starts to dip below 60F or so. But to hear some people describe it, you'd think we need a parka and mittens up there! So which is it? Thanks in advance.
