I like Vancouver's mix of weather.
We generally get good summers, this summer is especially dry, over 42 days no rain. We generally get a few hot days, but mostly in the high to mid 20's range in summer. Again, this summer is hotter, with having that heat dome earlier, and now this week temps getting up to 32 C. If you want hotter temps, you simply go inland a bit and they jump up.
Swimming in the ocean, is done, and is usually refreshing
but today the ocean temp is 20.5 C. Totally doable.
As for the rest of the year, autumn can be beautiful, and frankly as much as I like hot and sunny, I also like a bit cool and rainy days.
Winters rarely get snow, but it's available 20 minutes from downtown on one of the local mountains.
Spring is spectacular, but some flowers start blooming in late February.
I couldn't live in a place that didn't have a certain amount of change in seasons since it brings changes in eating habits and clothing. I like that.
That said, I don't think I'd like super cold winters, I'm to wet coast for that.
The gloomiest months for me are November, and January. December you don't notice, too busy with the holidays.
