Phoenix Sky Harbor hit 90º for the first time this year around 1:18 pm on March 25th, but the thermometer did not stop there. It continued rising until reaching a high of 96º, which broke the record for the day of 93º set back in 1988.

A fun fact, this is the second warmest high temperature on record to be measured on the first 90º+ day. The hottest first 90º+ day comes in at 97º, which occurred in 1946 and 2019.

And if you were wondering, the average first 90º+ day is March 30th.

What an end to 2021 in Phoenix! First, the Valley had the wettest Christmas Eve on record. Then it rained on Christmas Day, New Year's Eve, and New Year's Day, which set another unique weather record.

So how much rain fell? From Dec 24, 2021 through Jan 1, 2022, Phoenix Sky Harbor measured 1.22" of rain. For this time period, this ranks as the 8th wettest since records began in 1896. While certainly not the wettest, there was measurable rain on six days, which did set the record. The old record was five days set in 1906 and 1941.

This winter season (2021-2022), something happened that has not occurred since weather records began in 1896!

Measurable rain was recorded on Christmas Day, Christmas Eve, New Year's Eve, and New Year's Day! The old "record" was three of the four big holidays in the same season set in 1941, 1959, and 2016.

If you like rain, this was certainly a nice change!

Christmas Eve 2021 will go down in the record books as the wettest since records began in 1896! Phoenix Sky Harbor measured 1.00" of rain, breaking the old record of 0.93" set back in 1944.

This marks only the 13th time measurable rain has fallen on Christmas Eve in Phoenix!

If you like rain, this was certainly a nice present from Mother Nature!

It might be December, but this afternoon the high was 85º, which is the average high we usually see at the end of October! This high also broke the record for the day, with the old record being 83º set in 1949.

Temperatures at or above 85º in December are very rare. In fact, there have only been three other times since 1896 where the high in December was 85º+. It happened two times in 1980 (86º on December 16th and 85º on December 26th) and one time in 1950 (87º on December 10th).

There is good news on the horizon with slightly cooler temperatures, albeit still above average, moving into the weather picture by the weekend.

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.

During the early morning hours of November 23rd, cloud cover overhead made temperatures stay warm overnight, with a low at Phoenix Sky Harbor coming in at 64º.

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.

It has been a warm November in Phoenix, with every day (through November 20th) seeing a high of 80º or higher, which has not happened since records began in 1896.

As for the total number of 80º+ days in November, that record stands at 24 and was set in 1949. So far this month, we are at 20 days, which stands as the 4th most for the month of November.

Rankings:
24 days in 1949
23 days in 2017
21 days in 1932
20 days in 2012, 1984, 1954 (now 2021)

With the 80s likely to continue through Monday, this November will likely make it into at least the number three spot.
