There are many ways to tell if it is going to rain besides the newspaper. Folk traditions involve things such as: the direction a lizard sits on a fence post, the location of a spider web, the way fireflies fly, where cows lie down, and cricket songs. The most important predictions are made on July 15, the day honoring St. Swithin's, the patron saint of the farmer. Current weather phenomena might also predict future weather. It is said, for example, fog on a southerly wind will bring rain, while halos around the sun foretell stormy weather.
