Special Weather Statement issued May 25 at 5:59AM EDT by NWS Caribou ME

Effective: Mon May 25, 2026, 5:59 AM
Expires: Mon May 25, 2026, 8:00 PM

* Many people will be recreating outdoors on this Memorial Day, and people may underestimate the dangers of the cold water temperatures which are currently only in the lower 50s on the lakes and around 50 on the rivers. * The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. According to the Maine Warden Service, when the water temperature is below 60 degrees, the average submerged person could lose 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! * Strong winds are also expected this weekend with gusts up to 25 mph from the south. 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.
