Unusually Cold June Weather

My tomatoes are not growing. They have fruit, but day to day the fruit does not ripen. Peppers and eggplant; the same. I'll grant, this is my first experience trying to garden at a higher altitude, 3500' elevation. But it's now Mid-June and I'm still using the fireplace most evenings. The summer garden does not like the nightly chill. My vegetables are responding to the low average temperature.

I was speaking with an elderly local gardener yesterday. She's grown a garden on the same land every year for the last 50 years; her mother grew vegetable gardens on the same parcel for the 50 years previous. This gardener stated that she's seen the seasons shift dramatically in the last decade. "We used to have the last big rain storm in April...then it began coming in May. Now, this year it came in early June. I used to have my garden finish by early October. Now, I still harvest a bit at Thanksgiving."

The local gold "miners" are disgruntled. They are used to being able to dredge for gold in the Yuba River as the roaring river waters decline to a safe margin in June. This year the few who thought to try have lost expensive equipment as the river floods with rainstorms up in the high country. Historically, the Yuba River systems have been safe for recreational swimming after the 4th of July.
This year I can look up to the mountain tops and see the heads of rain-filled thunderclouds. This is not a year like other years.

The people in town are speaking of the weather daily. What used to be a trivial conversational topic is now as much a concern as the economic "weather". The general consensus is that this is uncomfortable, uneasy weather; cool and wet. "Foothill" gardeners, as we are known by, are used to odd weather events; hail storms in June, even a freak late snowstorm several years ago. We sometimes (rarely) receive rain in our dry summer season. When we do it is always a cause for rejoicing because it lessens the danger of fire season. This year feels different. We don't know what the weather will bring. We do have an uneasy sense that it's a bit different, that something is out of pattern. An essential weave that we have depended upon and taken for granted has shifted.
