I always bring at least a sweatshirt when I go home to Colorado. Dry air cools down much faster than humidity and shade has much more impact

Anyplace where ridges or mountains trap hot/cool air.

Lots of places especially if you are hiking as it will be warm down low and cooler up high.

We went to British Columbia last summer and huge temperature difference between Vancouver, Whistler and even different areas of Vancouver Island.

Maybe try switching to merino wool to handle these extremes.

Seattle.

My DD's school is by the lake and the layers she puts on and off during the day are never the same as what she would need if she was at DH's office on the Puget Sound or at our house. In the summer it's especially pronounced. We have access to a swim club and a beach club on different sides of town, and sometimes will keep plans in the air until we see which way the summer clouds/fog/burnoff is moving.

It drives me nuts because as an east coast person I want to put away all of the jackets and sweaters and sweatshirts for summer, but can't.

I was in SF last summer and surely could have used a puffy. The windchill made it quite frigid.

We were in Madeira in April and had to pack for all seasons.

Op here. Swimsuits for San Jose and puffies for the fog line.

I was in SF recently and dressed in layers. When the sun was out and I was walking a lot, I got warm and didn’t need a sweater or jacket. When it was cloudy and windy, it was cold enough to warrant a jacket. And after dark, it was legit cold.

But I didn’t see anyone in a tank top let alone a swimsuit. If you go on a boat, it’s colder, not warmer.

Puffy jackets for summer time? Yes it gets cool but rarely below 55 or so except overnight, I've never needed anything more than a light jacket, visit family in the area pretty often in the summer.

The southwest in general depending on elevation. You can go from snow to 70’s in AZ, NM, etc.

Also depends on the residents and visitors and their sensibilities. Whenever we go to Europe on shoulder seasons we marvel at how bundled up they are. Meanwhile Canadians be like
