I have created a page that displays growing season markers for Washington from 2013 to present. On the page, I list dates, varieties, and location for:

Bud break
Bloom
Veraison
Harvest

I also show the average date for each of these markers, the median date, and the range from 2013 to present. I give an example of what this looks like below.

On the table, I am listing the first date that the marker was reported for any variety. This stands in contrast to listing 25%, 50%, etc. for a single variety at a single location. The overall intent is to give a general sense of how each growing season relates to other vintages. It is not to give a specific sense of this relationship.

This information is based on personal correspondence as well as social media posts. I want to thank Sagemoor Vineyards specifically for their help over the years collecting data.

Going forward, growing season marker summary information can be found under the main menu: Resources->Vintage Information-> WA Season Markers. Click here to see the full table. Please note that this information is restricted to subscribers. Click here to subscribe.
