30 November 2021 - Posted in Weather Records by Weather Bus

On the last day of November in Phoenix, the high was 80º, making it the 25th day during the month with a high of 80º or higher. This breaks the record for the most 80º+ days during the month. The old record was 24 days set back in 1949!

The top years for November include: 25 days: 2021 24 days: 1949 23 days: 2017 21 days: 1932 20 days: 2012, 1981, 1954

As for the least number of days with a high of 80º+ in November, that record is zero and has happened 4 times (1920, 1938, 1957 and 2000).

Also, if you are keeping track, the high of 80º on November 30th was 10º above the average for this time of year and marks the 191st above-average high temperature day so far this year. Some good news, this is better than last year, as at this same time in 2020, we were at 224 days that recorded an above-average high.

First low below 50º in Phoenix this season!

The low temperature at Phoenix Sky Harbor bottomed out at 49º during the morning of Sunday, November 28th. This low temperature marks the first time this fall with a low below 50 degrees.

If you thought it was a little late, you would be right; this year ties as the fourth latest on record. The latest on record is December 7th, which occurred in 2017. On the flip side, the earliest on record is September 20th, which occurred in 1965.

So is the first below 50 degree low temperature of the spring season getting later? Looking at data from 1896 to current (graph above), the answer is yes. The 30-year rolling average in 1925 had the first below 50-degree day occurring around October 17th. Using the last 30 years (including this year), the average is around November 13th.

Not only is this 13º above the average low for this time of year, but it also broke the record for the warmest low temperature for November 23rd. The old record was 60º set in 1965 and 1933.
