Based on a question I just got (nice to know people are paying attention), here is a little information about growing degree days (GDD) from the NEWA site.

You can find GDD 2 ways for a weather station. I go through the Degree Day Calculator under the Weather Data tab (which also has the 5 day forecast).  You have to change the Accumulation start date to March 1 and choose the station then click get report.

You can also go through the Station page and click on Growing Degree Days (Base 50F) then look at the current date under Accumulation since March 1. It is a day behind – I think because it is calculating the information on actual data.

I think knowing what is supposed to happen is useful for planning so I send out that information.

Here’s what I see for Geneva today:

I hope this is helpful!
