San Francisco? Seems to reach 20C every winter but has average highs below 20C in July.

DINGDINGDINGDING- yes, SF fails to reach 20C more than half of days in July but typically reaches it every month of the year at least once (including December and January).

I live only 40 miles inland, and where I live, due to our microclimates, every day from June through September is guaranteed to break 20 C. Like SF, we typically break 20 C, 2-3 times a month in peak winter months as well (December through February). We have not yet hit our first sub-20C high of fall but we came pretty close on this past Saturday (high was 69 F and it was also the first rainfall of the season after our typical bone dry summer). I predict we will fail to hit 20C for the first time sometime in mid-October.

The lowest temperature I've ever experienced here was 22c. And that was only because of the 14-hour rain blocking the sun.

April 24 - October 12 for the average highs.

Although 20c isn't uncommon before that. We have hit that temp several times in February this year, even more in March. So far this April, most days have been around that temp.

It's possible anytime between April and October but generally speaking only the months of July and August will record a majority of days above 20C.

Omaha did not hit 20 C "several times" this February considering their highest temp was 18 C and it's surrounded by most days not even hitting freezing


Omaha hit 20 C a grand total of 5 times in March, which was usually quickly followed by a huge temperature drop. And April so far has an average high of 52 F/11 C , are you just pulling stats out of your ass? I will never understand why people try to make their climate seem warmer/colder than they really are


Here in Miami, every month has an average high well above 20 C, but between late November- mid March we will see a few days with high below that, sometimes even below 15 C or in some cases 10 C.
