Special Weather Statement
Issued: 9:15 AM May. 25, 2026 – National Weather Service
...National Weather Service Cold Water Safety Message...

* The warm air temperatures later today in the 60s and 70s 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!

* Due to recent rain, area rivers may run fast with swift water
currents. The swift water can easily overturn a kayak or canoe into
the frigid river waters. Once in the cold water, the strong
currents will make it difficult to reach safety.
