which city is hotter, Sunnyvale or Foster City? (San Jose, Daly City: apartments, condos)

Since Foster City is directly by the bay, I would assume it is cooler in Summer. However, I checked the temperature statistics and surprisingly Sunnyvale has no month with average high higher than 80, but Foster City has two.

I understand that temperature isn't everything when it comes to how hot you feel. I also noticed that more apartments are equipped with central AC in Sunnyvale than in Foster City (In Foster City almost none of the apartments have AC, including the so called luxury ones, but in Sunnyvale most big complexes have that. The few ones that don't have it are condos). So for anyone who lived at close to both places, which one feels cooler in sumer?

I've only lived in San Jose near Milpitas and Daly City, and I think San Jose is too hot for me without AC. Daly City is fine. I assumed Sunnyvale is like San Jose since it is so close, but the temperature statistics shows otherwise. Sunnyvale's average high are 77, 79, 79, 78 for June to Sep. San Jose's average high are 80.5, 84.3, 86.6, 80.5. It seems Sunnyvale is way cooler than San Jose or Milptias in the summer.

FC is breezier and I find it cooler than Sunnyvale.

Foster City is much windier and would likely be breezy every afternoon. It does occasionally get warm and not having A/C during that time would sort of suck. However, it seems to be the exception to the rule.

Sunnyvale's average temps are lower since it is closer to the Bay. This is at least true for where downtown Sunnyvale is located, which is probably about 2 miles due south of Moffett Field. So, there is a pretty good sea breeze that blows straight down the bay and often keeps the temps slightly cooler than SJ or Milpitas, which lie to the Southeast of the bay and somewhat further inland. Its usually pleasantly warm and very rarely hot. However, on the hot days, it is nice to have A/C in this area.
