About RainMapper

How much rain fell at your home yesterday? Official rainfall amounts are usually measured at the airport, far from where we live. And most of us don't have our own rain gauges. How do you know if there was enough rain so you can delay irrigating your landscaping? Rainlog.org is a web-based network of hundreds of volunteer weather watchers that measure and report rainfall in their backyards.

RainMapper is a free service based on RainLog, developed at the University of Arizona with support from the Bureau of Reclamation. Register below for the free RainMapper service, and we'll provide you with information on how much rain fell in your neighborhood, every time it rains within 5 miles of your location if observations are available.

Note: If what you wish is to report precipitation then proceed to the Rainlog registration page.
