The record high is 111, but that's not really that extreme; even Cleveland hit 104 once. In fact, Wikipedia claims San Diego sees only 2.5 days per year above 90, so it certainly isn't fair to call its summers hot. Especially by humidex, seeing as it is extremely dry. And on the other end, it has a shocking 0 days below freezing per year.
It sounds like a pretty perfect climate if you don't want to grow anything.
Again, as noted earlier, all of those "official" temp measurements are taken spitting distance (literally) away from the waters of mission bay, which gives an unrealistic impression of temperature on all official readouts. If you go a little inland (lets say Santee, which is inland a little bit, as it is a better representation of average temps in most of San Diego), the average high during Jul-September is about 85+ (https://weatherspark.com/y/2071/Average ... Year-Round
) and the monthly maximums are 100+ for every month between June to November (http://www.areavibes.com/santee-ca/weather/
). This is the trend for the areas of San Diego that people actually live in, not just the tiny microclimate at the part of the airport directly next to the water.
