Snohomish County Weather Data

Snohomish County weather data

In 2008, WSU Snohomish County purchased four Avatel data loggers for collecting temperature data through the growing season. In 2008 we were only successful in collecting data from one site in the County but did much better in 2009. We will be collecting data annually from several locations.

Below you can download the data collected from diverse areas of Snohomish County to calculate degree-days.
