We should have menitoned this earlier. Spring water temperatures lag behind air temp, for example in Maine right now the water temp ranges from the upper 40s to low 50s°F (4 to 11°C). It's a beautiful warm day so folks start putting their small boats in the water. At these temperatures, the risk of cold water shock and hypothermia is extremely high and life-threatening.
The Hypothermia and Cold Water Risk
- Cold Water Shock (Immediate Risk): Water conducts heat away from your skin 4 times faster than air. Sudden immersion in 40-50°F water triggers involuntary gasping, hyperventilation, and elevated heart rates, which can lead to drowning in seconds.
- Loss of Dexterity & Incapacitation: In water below 60°F, you can lose the use of your hands and arms in under 10 minutes, making it incredibly difficult to stay afloat or perform self-rescue.
- Expected Survival Time: At 40–50°F, exhaustion or unconsciousness occurs in 30 to 60 minutes, and maximum expected survival time is only 1 to 3 hours.
Essential Safety Guidelines
- Always wear a life jacket: The Coast Guard and Maine Warden Service strongly advise wearing a well-fitting, Coast Guard-approved life jacket whenever we are on or near the water
during the spring....(How about all the time when we are on water depths over our head? - Dress for the water, not the air: Even if the spring air warms into the 60s or 70s, the ocean remains lethally cold. Wearing a wetsuit or dry suit is highly recommended for all on-water activities.
- Track the current data: Before heading out, you can check real-time marine forecasts for the region.
PFD - Wear it.
- End of post quiz...In the photos below, when should we be wearing a PFD?
