It's hard to compare PNW with the New England but we had very mild weather last fall. If I remember well into November and even early December. Than wham! It got cold fast. By the end of the month we were seeing well below freezing temp and single digits regularly. It was cold enough long enough to get some ice in the bays. The only reason there wasn't more ice was because the water started more warm due to the mild fall. I'm not complaining about that since I think the bays need a spat of cold weather to be healthy. But now it's April, the sun is strong and it's time for warmer weather. BTW the water clarity here is very good due to the, I think, cold spell and the lack of gully washing rains. We've had rain but not so much the type that overwhelms the drainage systems and washes into the bays. I hope I can swim in that water soon!
What was the topic again?
We had a similar season in 2017 (I agree, I don't see us sharing similar weather). The sailing season was cooler than normal. While I didn't haul out until the second week of November, our typical prolonged coastal fall, was cut short by the early and cold winter.
Now, the winter is lingering here on our coast. But I never expect it to warm much around here in spring. The North Atlantic calls the shots on our weather during spring. I don't look at the thermometer much this time of year; I look at a nearby flag to see the wind direction, to decide what to wear. The ocean is cold.
Our sailing seasons are a little unpredictable these days. The Gulf of Maine is warming faster than nearly any ocean body on the planet, especially in the last 10 or so years. Beyond climate change in general, the rapid warming of the Gulf is due to the flow patterns of the Gulf Stream and the North Atlantic. Current paths are shifting.
We've seen the results first hand, sailing Penobscot Bay. Last season, we didn't swim in the bay. 2 and 3 seasons past, we did swim, quite a bit. I took to hanging a thermometer in the water at various anchorages and would occasionally find water creeping up to 70 degrees (normally it's low to mid 60's in Aug). That rare 70F is warm for coastal Maine. During many of our beautiful warm August days (that can be very hot in the bright sun), we enjoyed swimming off the boat in the last few seasons. That's something we very rarely did for in the last couple decades of sailing the coast of Maine(and we were younger!).
We could just as well see our 2018 season be colder than normal (we tend to go through 2-3 year dips and rises in the water temperature), but there's a better likelihood, this season will be quite warm.
I see this as a bright side to climate change. I'll live and sail this warming trend in the Gulf of Maine as we continue to track longer and warmer seasons.
