• How do you read a barometer?
A barometer displays the current air pressure. For a weather forecast, you look at the difference from the previous reading and how quickly the pressure has changed. Rapid pressure changes indicate short-term weather changes; slow changes indicate longer-lasting weather changes.

• Where do I hang my barometer?
Air pressure is the same everywhere, but avoid locations in direct sunlight or above a heat source such as a stove. A prominent location in the boat or indoors ensures that you immediately notice pressure changes.

• How do I adjust my barometer?
Most barometers are factory-set. You can look up the current air pressure online and adjust the needle if necessary with a screw on the back of the mechanical barometer. If you have any questions, we're happy to help!

• Does a barometer work at any altitude?
Barometers are set to sea level. A few floors up a building usually don't make a difference, but for use at higher altitudes, such as in the mountains, calibration is necessary.
