We arrived in Crescent City about five days before our redwoods workshop was set to begin. Our first night there some showers moved through, and at sunrise it was gray and raining. But online radar and satellite images showed that the showers might end soon, so I prepared to go out. Then through our hotel room window I saw a rainbow! We made a dash for the car, drove out to Crescent Beach, and luckily the rainbow was still there (right).
The weather then settled into a more typical pattern for the season, with frequent coastal fog and low clouds in the mornings, giving way to clear skies in the afternoons. This pattern should be familiar to anyone who has spent time along the California coast in summer.
This fog is the perfect complement to redwood forests. The rhododendrons were also putting on a great display this year, so for the first part of our workshop, and while scouting beforehand, we had beautiful conditions in the redwoods, with fog, rhododendrons, and even sunbeams.
But on the last day of the workshop the wind shifted and pushed the coastal fog offshore. This also happens frequently along the northern California coast, even in summer, as any disturbance in the weather pattern can change the winds and move the fog out to sea. But the offshore wind produced a different kind of fog – valley fog along the Klamath River. I didn’t think we would see valley fog during this visit, because valley fog usually requires damp ground from recent rains, and there hadn’t been much rain in the area. But apparently the river itself provided enough moisture to create fog.
This time the fog flowed along the river toward the sea, and it was local enough, and low enough, for us to get above it near the mouth of the Klamath River. It was a special treat to look out over the fog bank, and then to watch and photograph the sun breaking through the fog and lighting the surf.
