2009 season

We finally had our first frost, which, to me, signals the end of the growing season. It came a month late, so I had plenty of time to prepare for it.

Only hardy crops left now. With a proper greenhouse or cold frame, I could protect more tender vegetables through winter. I have some lettuce, spinach, and arugula still going, so I hope to finish up a few cold frames to keep them alive.

We had an amazing spring and summer this year. By far the hottest and driest since I've lived in Whatcom county. Up here, rain can be just as much an enemy as an ally. In a wet year, we fight mildews, molds, and early blights, and plant twice as many tomatoes and peppers as we think we need to make up for pitiful harvests. In a dry year, we don't complain - just water a bit more and enjoy the sun!

Frost free from March 10 - November 14; that's 249 days, or 8 months and 4 days, an extra long season for us. You can see that we have a pretty reliable wind, primarily a breeze from the SW in the summer. Note the change in wind direction from late summer into fall. We get our fall and winter "Nor'easters" (cold and powerful NE windstorms from the Fraser Valley in Canada) pretty regularly that time of year. In October and November, it's pretty clear that the spikes in average wind speed fall on the days of NE winds. Also of note is the rarity of rainfall this year - only 3 or 4 days of measurable (and it was barely that) precipitation from mid-May through mid-September.

For me, keeping track of the weather each year is crucial. I plan when to start my seeds in late-winter based on when our last spring frost will occur. I calculate at what date in summer I must plant fall crops in order to mature them before cold weather sets in based on our first frost date. The length of the growing season helps me determine which varieties of certain crops to grow, based on whether or not our season is long and hot enough. For a real farmer (one who depends on farming for their livelihood) favorable weather can mean keeping the farm and poor weather can mean bankruptcy. Yikes!
