Questions arose at Monday’s meeting on the topic of ocean water temperatures, in relation to cold water shock and hypothermia in local waters.
It seems that there are abundant data, although it isn’t quite clear to me how the measurements are taken i.e. at what depth. Assuming these are surface (or near-to-surface) temperatures, here is what the web site http://www.seatemperatureinfo.com shows for today:
Ucluelet 7.8 C (annual mean range is about 8 C winter to 13 C in summer)
Interestingly, the Strait of Georgia is slightly colder in winter, presumably due to runoff and less influence from warm currents, but gets quite warm in summer, especially where flushing is minimal, like in Desolation Sd.
Hornby Island 7.4 C (annual mean range is about 7 C winter to 17 C in summer with occasional days reaching over 20 C.)
I’ve measured 22 C at the surface in summer in Howe Sd.
So most of the year, but not necessarily every day in July & August , you should be wearing your thermal protection.
In addition, I’ve noticed how much colder than our ocean are local lakes and rivers. Brrr.
