A weather forecasting device comprises a pair of contacts disposed a predetermined distance apart from each other and a switch plate disposed between the contacts. The switch plate is movable between the contacts in response to changes in atmospheric pressure and the manner of contact between the switch plate and the two contacts is used to detect the direction and amount of change in atmospheric pressure. On the basis of the results of such detection, probable weather changes are successively forecasted.
