You can just go out at the beaches in the sun light where snorkeling and scuba diving are the activities you can perform. http://hawaii-travel-attractions.blogspot.com/ Well….whos thinking of ice in hawaii.There is never snow there.

If I may add my own observation (this would be a great science fair project) vis-a-vis snow melt: One of the forecasters mentioned that temperatures a couple days in January exceeded 50 degrees, and there have been plenty more days above freezing since the last snow. ... The extremely dry air most of the time may have hindered melting. I live in New Hampshire and track snowfall and snow depths from several informal spotters at http://wermenh.com/sdd/index.html . A common reference here is to "snow eating fog," but I think that has cause and effect reversed. When the dew point is above freezing, water condenses on snow, and the release of latent heat melts the snow and that keeps the released heat from warming the air. So the snow still cools the air, causing fog to form. We commonly see warm (50ish) moist outbreaks in March and can see the fog slipping downslope over a snow field. Not snow field like Denali or even Mauna Kea, but snow field like someone's front yard or hilltop church. I don't have good numbers to share, but whenever we have a forecast for warm weather I look at the dew point to estimate how much melting may occur. 50 degrees on a north slope with sub freezing dew points? Even our dense atmosphere here at 350 ASL can't melt much. Congratulations again - I'm looking forward to the snowshot pages and will be happy to link to them from my climate page. (Yes, I understand weather is not climate, but it is raw data for climate....) [Here via http://wattsupwiththat.com/tips-and-notes-to-wuwt/ ]
