What is CoCoRaHS?

The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) is a grassroots, non-profit, community-based, high density precipitation network made up of volunteers from all backgrounds and ages who take daily measurements of 'just precipitation' right in their own backyards. Given the variable pattern of rainfall over Florida, it's important to understand just how much rain fell in an area. How many times have you heard the rainfall report from an official gauge and thought to yourself: That's not what I got?

This is your chance to help. By providing your daily precipitation data, you truly help many in Florida in one way or another - whether it's agricultural specialists, National Weather Service meteorologists, forestry officials, water management employees or emergency management personnel.

So, you want to become an observer?

It's easy to sign-up to become an observer through Once you sign up, someone will contact you with all the information (station name, station number and login support) you need to get your station up and running.

You'll need a few 'tools of the trade' in order to be a successful observer:

  • The desire and commitment to help study and learn about precipitation and storms
  • A 4-inch rain gauge and your own unique station number and name
  • Training
  • Internet access

Need a rain gauge?

You can purchase an official CoCoRaHS rain gauge for $29.95 from the following suppliers:

Before you start, you need to be trained.

In order to properly set up your rain gauge and to learn how to accurately read your rain gauge (yes, there is a wrong way to do it!), you'll need some training. You can read through the training seminar online at We hope to have in-person training seminars in the future!
