To estimate the average rainfall, collect rainfall data over a specific period and location. Sum the total amount of rainfall recorded and divide by the number of measurements taken. For example, if it rained 100 mm over 20 days, the average would be calculated as 100 mm / 20 days = 5 mm/day. Consistent data recording is crucial for accuracy.
