The Rainometer is a Science structure that predicts precipitation. Like the Thermal Measurer, which predicts the season, the Rainometer predicts when Rain is coming. The Rainometer has 3 stages, Sunny, Cloudy, and Raining. The arrow in the middle shows what weather is imminent or occurring at the time.
- The Rainometer was added in the A Little Rain Must Fall update.
