PREDICT WEATHER WITH AN ALTIMETER
The altimeter on your watch gauges altitude by measuring air pressure: Falling pressure means you’re climbing, and rising pressure translates to going downhill. Dropping air pressure usually indicates an approaching storm system, while a rise in pressure means the weather is clearing. So if your altimeter says you’re hiking uphill and you’re not, pull out the rain shell: Foul weather is likely headed your way.
