After he said that, I had a look at actual data out of curiosity, July 2015 in Napa. Note the 47 degree night, in July!

It's much more pleasant, imo, when daytime highs and lows are with 10 degrees of each other. 85-75, the kind of weather we're getting now in Miami is perfect. Allows you to dress one way throughout the day and night, nights feel pleasant but not cold, daytimes feel warm but not hot. I can be out on my balcony and be comfortable.

I agree, that is why I loved summers in San Diego, could dress the same all day and night. Though one thing I will give the cool evenings is not having to use AC at night, I do appreciate being able to cool the house down at night and open the windows. I hate using AC especially at night and it's so expensive with our electricity rates.

Ya thats only one night though.. On average its about mid 80's down to upper 50's or 60. Doesnt seem too shabby, cool at night is good for sleeping.

Here in new england its the opposite climate and it sucks! Winters are cold and dry so your skin is basically falling off, when we finally get hot weather it is often very humid and unpleasant so you need AC.

Worst of both worlds

Yeah North Bay seems to have some really cool summer nights even with the heat. My dad lives in Ukiah where it's hotter during the day than where I live (Central CoCo County) but it still cools off much faster.

65 and windy is cold IMO for July weather even in day time. Winter temps are similar to a few degrees warmer compared to the rest of the bay area. Low temps almost never going below 40 nor is there frost in SF. The summer kills you when you are a tourist from the midwest visiting in July expecting warm sunny stereotypical CA weather and being greeted with the cool breeze while you are wearing shorts and a t-shirt.

It is a problem for evening festivities that usually run from 6PM to about 9 or 10PM because of the drastic temperature drop in those hours. Personally, I think daytime highs of 80-85F paired with overnight lows of 65-68F are perfect on both ends; warm enough to swim during the day and balmy enough for summer festivities in the evening (remains above 70 until close to midnight), yet still enough cooling to sleep with the windows open and cool things off in the house. Last summer San Diego got several nights with lows in the mid 70s at the coast after daytime highs in the mid 80s to low 90s and that was problematic for people without AC to sleep.

If you compared an equal distance from the ocean, SF might end up with less sun than SD. Directly on the coast at the beach, I think SD is sunnier and feels A LOT warmer overall.

Yes, this.

If you compare the beach in SF to the beach in SD, SD will be sunnier. The SF station is in one of the sunniest parts of town and the SD station is in one of the cloudier parts of town.

You pretty much described the perfect weather of coastal Southern Cal. Subtract 10 degrees and you have coastal NorCal - 70-75F paired with overnight lows of 55-59F in the summer. Both are great in my opinion.

Very slight adjustment needed to climatize should you move from one to the other. Coupled with rainless days for 5-6 months means just about everyday is good for outdoor activities.

If you are coming from just about anywhere in USA, both of these climates are near perfect if you are looking for mild, slight variation, very little need for heat or a/c, and limited days of inclement weather. You will need your a/c a little bit more in coastal SoCal, but less need for heat. The opposite for coastal NorCal, you will need your heat a little bit more, and a lot less need for a/c than SoCal.

SF, SD, and coastal LA folks have a very difficult time understanding that any variation of the weather further inland does not mean the weather is "bad", "hot", nor "cold" when comparing these places with the rest of the nation.

For example describing , Walnut Creek, Napa, and Sacramento as "hot" without clarifying, or that Sacramento, Santa Rosa, or Stockton are "cold" without clarifying characterizes these places as having "bad" weather, when they all have GREAT weather compared to the rest of the nation both in the winter and SUMMER.

Costal NorCal is more like 60-70 during summer max, a lot more windy, and foggy than coastal SoCal. Santa Cruz being an exception. I wouldn't call it a "slight adjustment" at all.

For the majority of Americans around the country adjustment is marginal in comparing the differences between coastal SoCal and coastal NorCal. As a Californian I never quite understood how folks from the east coast described the Bay Area as sunny and warm but now I do after traveling all over the country it is easy to see that coastal SoCal and NorCal are much more alike than different compared to other places around the country.

Having said that, the direct coast of say Ocean Beach in SF compared to PB in SD you will definitely feel a difference because SF ,likely will be windier longer, and the wind combined with just a 5-10 degree difference will make it feel it colder. Thicker, colder and longer lasting fog in SF than in SD.
