Find a sturdy plastic or wooden box that can be placed on its side. Before you take the box outside, attach a thermometer to the bottom of the box. Once you turn the box on its side, the thermometer will be in the back of the box, protected from direct weather conditions. Take your box outside and find a safe, sturdy location on the north side of the building where it's shadiest. Position the box securely beside the building, perhaps on a brick foundation.
Every meteorologist needs to keep a good weather journal.
Remember, good observations make good forecasts. Since barometers are very sensitive to minor changes in weather conditions, you'll want to keep the barometer indoors to get more accurate readings. Make Your Own Hygrometer Place your hygrometer outdoors, inside your weatherproof weather station box. The hygrometer will measure the amount of moisture in the air, or humidity. Your rain gauge needs to be kept outdoors, but not inside the weatherproof box.
