Which cities have the best summers?

I can think of 2 candidates:

Seattle: Notable because of how long daylight lasts (can be sunny at 6 am until 10 pm or so at peak), and the weather. In the early 2000s you basically only wanted air conditioning a few days, rain was rare, not humid, arguably the best summer weather overall in the US. Now there are more hot days and wildfires so not quite as optimal but still very good. Combine that with what is likely the most beautiful surrounding area in the continental US.

Chicago: Notable because of how the lakefront really comes alive and the large number of festivals, free performances etc. Because of the winters everything is concentrated into summer.
