After passing the Brooks Peninsula on June 30, July has brought very weird and challenging weather. It doesn’t feel like summer, and we’ve gone many days not even seeing the sun, because it’s obscured behind a heavy cloud layer. We’ve had rain about half the days; normally in Seattle we count on summer arriving after the 4th of July, but that hasn’t seemed the case on the west coast of Vancouver Island.
The weather varies between chilly to warm and very humid (90% humidity). The humid days are completely overcast, darkening the sky and reducing solar output. It feels like a Hawaiian rainforest, but without the sun. Other times, the temperature has been chillier than we had a month and a half ago, in late May on the Central Coast. We’ve been wearing foulies and fleeces in July, which seems very weird.
BC weather forecasting says there’s a ridge offshore and a quasi-stationary trough over the mainland, but I don’t know if that explains things or not. Someone we met at Nuchatlitz said there’s an inversion going on, which explains things a lot better (we’re quite familiar with inversions in Seattle, but they usually happen in the spring or fall, not summer!). An inversion, as I understand it, means warmer, clearer air is stuck above a dense cloud layer. People at ground level (ie, anyone on a boat) experience dark, chilly conditions, but if you could hike up 5000 feet or so you’d get to nice sunny conditions. It also means little wind – if there were wind, it would blow out the inversion.
The lack of wind has been the most frustrating part. It’s almost like we’re in the doldrums, the ITCZ, or the South Sound in August. Our last 4 days in Kyoquot Sound didn’t have a single hour with wind over 5 knots. And when we “sailed” to Esperanza Inlet on a forecast of NW 5-15, we had to motor pretty much the whole way because there wasn’t more than 4 knots on the ocean the whole day.
