1. Select the date you would like to make a prediction for, from the bar at the top. The next available date is selected by default.
TIP: The value shown on the date is the current cost to make a prediction on that date.
2. Find a location where you think there will be rain. Check out the forecast maps at the bottom of this page.
TIP: The larger the bubble, the more people making predictions there.
3. Choose the amount of rain you think will fall and submit your prediction. If you're a bit under you'll still earn a partial payout, but if you're over you'll lose it all!
TIP: The bar graph shows where other people are predicting, and the current forecasts.
