Spring on the Seacoast: Warm Weather, Cold Water

🔴 Air temperatures are in the 70s, but lakes and oceans are only in the upper 40s and low 50s

🔴 Hypothermia can set in quickly for those not dressed appropriately

🔴 Low humidity could being an elevated fire risk on Saturday

With warm weather expected all weekend around the Seacoast, the first swim or boating trip of the season could be a good way to cool off.

It's probably not a good idea, according to the National Weather Service in Gray, Maine.

Temperatures Friday through Sunday are expected to climb into the 70s and low 80s under partly to mostly sunny skies. However, water temperatures in lakes and oceans are only in the upper 40s and low 50s, which can quickly cause hypothermia to set in for anyone in the water not properly protected.

"According to the US Coast Guard, when the water temperatures are below 50 degrees, the chance of immediate incapacitation due to cold shock is extremely high. Anyone on boats or paddlecraft should use extreme caution to avoid this threat," the National Weather Service said in a statement. "Always wear your life jacket. Be aware of wind conditions, tides, and localized currents."

Conditions will remain dry with low humidity, creating an elevated risk for fire on Saturday.
