WeatherBill, a company that lets you make money by betting on the weather, has raised $12.5 million.

The San Francisco-based company sells contracts that essentially let you put money down against bad weather hurting your business, so you can still get paid even if your business itself suffers.

You can choose your contract to be for hot, cold, rainy, snowy or dry days or seasons, and customize every specific aspect of your scenario, such as the temperature, precipitation or snow level. Choose a location with all of your weather specifications and how much you hope to earn from the contract, and the site will calculate its cost.
