What is the Wind Chill Calculator?
Wind chill is the apparent temperature felt on exposed skin due to wind. It reflects how quickly the body loses heat in wind.
Wind chill reflects heat loss from exposed skin. At sea, spray and moisture can make it feel colder than the formula suggests.

Formula
Core relationship: Wind chill (°F) = 35.74 + 0.6215×T − 35.75×V^0.16 + 0.4275×T×V^0.16
NWS wind chill formula: combines temperature and wind speed to estimate how cold it feels. Only applies when temp ≤ 50°F and wind ≥ 3 mph.
Wind chill reflects heat loss from exposed skin. At sea, spray and moisture can make it feel colder than the formula suggests.
Practical use cases
Wind Chill Calculator: passage planning, crew briefings, instrument-to-chart unit checks, and verifying mental math when tired or in rough weather.
Tips for accuracy
- Match input units to your chart, GPS, or instrument before trusting the Wind Chill Calculator.
- Cross-check important outputs with a second method or crew when visibility or motion is poor.
- Treat simplified models (waves, radar horizon, etc.) as estimates; real conditions vary.
Practical examples
- 35°F, 15 mph → ~24°F feels like
- 20°F, 25 mph → ~2°F feels like
Frequently Asked Questions
What is wind chill?
Wind chill is the apparent temperature felt on exposed skin due to wind. It reflects how quickly the body loses heat in wind.
Does wind chill affect boats?
Wind chill affects people on deck and can increase risk of hypothermia. It does not change the actual water or air temperature for equipment.
How accurate is this calculator?
It uses standard maritime formulas and noted approximations. Use it for planning and checks; confirm safety-critical decisions with official sources.
Can I use this on mobile?
Yes. Layouts are responsive for phones and tablets on deck or in the cockpit.
