Special Weather Statement issued May 24 at 12:25PM EDT by NWS Gray ME

Effective: Sun May 24, 2026, 12:25 PM
Expires: Sun May 24, 2026, 10:00 PM

* Temperatures this Holiday weekend may cause people to underestimate the dangers of the cold water temperatures which are currently only in the mid 50s across Sebago Lake and Lake Winnipesaukee, and in the mid 50s in the regions smaller lakes and rivers. * The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. When the water temperature is below 60 degrees, the average submerged person could loose dexterity within minutes and be unable to accomplish simple tasks. Anyone on small boats, canoes, or kayaks should plan accordingly if recreating this weekend and use extreme caution to avoid this threat. Paddle smart from the start and always wear your life jacket! * Winds will be breezy this afternoon with some gusts up to 25 mph across parts of the area. If boating on large bodies of water, these strong winds can increase the likelihood of overturning your boat, canoe, or kayak due to increased wave heights.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
