Tucson monthly climate reports for 2024

January 2024 climate report for Tucson
40th warmest and 16th wettest on record
Two daily rainfall records set. First time in January since 1993.
 

The January outlook from the Climate Prediction Center, issued on December 31st, for Tucson favored below-normal monthly mean temperatures (59% below vs. 8% above) and above-normal total precipitation amounts (46% above vs. 21% below).

 

The new year started on an unsettled note with a pair of weather systems moving across the area. The first system brought scattered very light showers to the area mainly on the 3rd while the second, much stronger, system brought widespread light rain, gusty winds, and some light snow to isolated areas of the metro on the 7th. Wind gusts of 30 to 40 mph were recorded before a cold front passage with temperatures dropping up to 10 degrees in 10 minutes with frontal passage.

 

The colder air mass led to the first widespread freezing event for the 2023-24 Winter season for the metro area with lows on the 9th in the 20s, coldest near washes as those areas dropped down into the low 20s. Chilly morning lows continued through the 13th. High temperatures from the 4th through the 12th were in the 50s. The exception was upper 40s on the 8th and lower 60s on the 10th.

 

An odd occurrence happened on the 12th (High 58°, Low 29°) and 13th (High 66°, Low 33°) when the high temperature was exactly double the low temperature both days. This daily double has only happened 23 times since 1894 with the most recent occurring in January 2016 (29th & 30th).

 

A gradual warming trend then took place over the next week with highs warming into the 70s from the 17th through 20th while lows moderated into the 40s on those days.

 

A significant pattern change brought widespread rain and mountain snow to the area over three days from the 21st through the 23rd. Three-day rainfall totals across the metro area ranged from 0.60" to 2" with localized spots up to 2.75". The airport set two daily rainfall records for this event. On the 21st, 0.81" was recorded which shattered the previous daily record of 0.40" from 1933 and 1982. Two days later, on the 23rd, 0.60" was recorded, which broke the previous daily record of 0.56" from 1985. This is the first January to set two daily rainfall records since 1993 when three were set.

 

Daily high temperatures from the 21st through the 26th were mostly in the 60s before high pressure aloft settled in during the last five days of the month, which resulted in daily highs mostly in the mid to upper 70s. The exception was on the 29th when the first 80° high temperature of 2024 was recorded. The climatological first date is February 1st.

 

The monthly average temperature of 52.8° is 0.8° below normal and ranks as the 40th warmest January on record, tied with 1943 & 1983. Temperature extremes for the month ranged from a high of 80° on the 29th to a low of 28° on the 9th.

 

The December 31st precipitation outlook for Tucson from the Climate Prediction Center favored above normal precipitation (40-50%) for January. Rainfall amounts, using several sources like rainlog.org, the Pima County Regional Flood Control District gages, and CoCoRaHS, ranged from 1.00" to 2.50" with localized spots up to 3.50". The Tucson International Airport, the official recording spot in Tucson, recorded 1.77" which is just under an inch above normal and ranks as the 16th wettest January on record. The first four months of the hydrological water year, October through January, has been wetter than normal with 3.71" being recorded at the airport, and ranks as the 44th wettest first four months of the water year.

Looking ahead into February

A strong El Niño will continue in the equatorial Pacific through the end of Winter.

February 2024 climate report for Tucson
26th warmest and 24th wettest on record
Highest February peak wind gust in the past 50 years
2nd warmest February daily low temperature
First 85°+ high of 2024 occurs on 25th
 

The February outlook for Tucson, issued on January 31st by the Climate Prediction Center, favored above-normal total precipitation amounts (52% above vs 15% below) and favored near-normal monthly mean temperatures (36% near Vs 33% for both above and below). The month was split into two periods, a wet first 11 days then a mostly dry and warm remainder of the month.

 

The first 11 days of the month were active as several winter storms moved across the area with rainfall occurring across the metro areas every day except for on the 4th and 5th. A thunderstorm on the 2nd produced brief heavy rain and pea-sized hail. On the 6th, strong gusty winds occurred in advance of another winter storm. The airport recorded a peak gust of 59 mph which is the highest February gust in the past 50 years. The coldest storm of the month impacted the area on the 10th with widespread valley rain and a little snow, mainly across the southeast portion of the metro area including Vail. The high temperature on the 10th of 48° was the 4th coldest February high this century.

 
A dry and warmer pattern settled in from the 12th through the 20th with the 2nd 80°+ high of 2024 occurring on the 20th. After a brief cool down from the 21st through the 24th, temperatures warmed up once again with the 25th being the warmest day of the month. The low temperature on the 26th, thanks to cloud cover, only cooled down to 61°. This ranks as the 2nd warmest February low temperature on record, behind the monthly record of 63° which occurred on February 1, 1929.
 
A pair of weaker weather systems brought light rainfall to the area on the 26th and 28th with a few thunderstorms rolling through the area on the 28th.
 

The monthly average temperature of 57.1° is 0.9° above normal and ranks as the 26th warmest February on record. Temperature extremes for the month ranged from a high of 86° on the 25th to a low of 35° on the 12th. This is the 26th February on record in which the official site didn't record a low temperature of 32° or colder. The last February that this occurred was in 2021. The high & low temperatures of 76° & 61° on the 26th have occurred together only once before since 1894, on May 3, 1915.

 
Precipitation across the metro area, using several sources like rainlog.org, the Pima County Regional Flood Control District gages, and CoCoRaHS, ranged from 1.00" to 2.00" with localized spots up to 3.00". The International airport, which is the official recording spot in Tucson, recorded 1.39" which is a little over a half an inch above normal and ranks as the 24th wettest February on record.

Winter 2023-2024 climate report for Tucson
11th warmest and 15th wettest on record
 

A strong El Niño was forecast to peak during the 2023-24 Winter season. El Niño typically brings an increased chance of wetter than normal conditions during the Winter months, December, January, and February. However, there was no model consensus to swing the chances of a wetter-than-normal winter for Tucson. Based on that assessment the temperature and precipitation outlook for Tucson, issued on November 17th by the Climate Prediction Center, called for the following:

  • a 33% chance that the seasonal mean temperatures will be below normal
  • a 33% chance that the seasonal mean temperatures will be above normal
  • a 33% chance that the seasonal total precipitation will be below normal
  • a 33% chance that the seasonal total precipitation will be above normal
 

There were several active periods this past winter that helped shape the season. Those active periods were 1) several days before Christmas; 2) mid-January; and 3) the first 10 days of February. The numerous winter storms that moved across the area brought much-needed precipitation in the form of valley rain and mountain snow. This helped improve drought conditions across the metro area from severe classification at the start of winter to moderate classification at the end of winter.

 

The seasonal average temperature of 55.5° is 1.2° above normal and goes into the record books as the 11th warmest on record, tied with Winter 1995-96 & Winter 2008-09. Temperature extremes ranged from a high of 86° on February 25th to a low of 28° on January 9th. Four days recorded freezing low temperatures at the airport, which all occurred in January. This is the third Winter on record in which all of the 32° or colder low-temperature days occurred in January. The other Winters were 1940-41 and 1962-63. This is also the 8th Winter season on record that recorded less than 5 days with lows of 32° or colder.

 

Precipitation across the metro area, using several sources like rainlog.org, the Pima County Regional Flood Control District gages, and CoCoRaHS, ranged widely from 3.25" to 6.00" with isolated spots up to 8". The Tucson International Airport, which is the official recording location in Tucson, recorded 4.63" which is nearly two inches above normal and ranks as the 15th wettest Winter season on record. The airport set three daily rainfall records (1.25" on December 22nd; 0.81" on January 21st and 0.60" on January 23rd). The last Winter season to record three or more daily rainfall records was Winter 1997-98 (3).

March 2024 climate report for Tucson
24th wettest and 54th warmest on record
Wettest March since 1998
Monthly high temperature coolest since 2000
March monthly high was cooler than the February monthly high
 

The March outlook for Tucson, issued on February 29th by the Climate Prediction Center, favored below-normal monthly mean temperatures (45% below vs 22% above) and equal chances for either below, near, or above-normal total precipitation amounts. The monthly average temperature was below normal which marks the third straight March that was below normal. On the precipitation side, it was wetter than normal.

 

The first five days of the month had highs in the 70s and lows being either 46° or 47°. Cooler temperatures settled in from the 6th to the 8th as a weather system passed through the state. This system brought widespread valley showers, high-elevation mountain snow, isolated thunderstorms, and small hail on the 7th and scattered lighter showers on the 8th. High temperatures on these three days were in the 60s.

 

Dry conditions and warmer temperatures, with highs in the 70s, returned to the area from the 9th through the 14th

 

Another weather system moved through the state on the 14th and 15th. This system brought scattered showers, high-elevation mountain snow, and a few thunderstorms to the area on the 15th. High temperatures from the 15th through the 17th were in the 60s before warming back into the 70s from the 18th through the 23rd. The exception was on the 22nd when highs across the metro area were in the lower 80s.

 

The third storm system of the month to impact the area brought gusty winds, widespread valley rain, and high-elevation mountain snow on the 24th and 25th. High temperatures once again were only in the 60s. Dry conditions and warmer temperatures returned to the area from the 27th to the 30th with highs in the lower 80s on the 29th and 30th.

 

The last storm system of the month brought gusty winds, widespread valley rain, and mountain snow on the 31st, Easter Sunday. This is the first widespread precipitation event to occur on Easter since 1999 when it snowed across parts of the metro area 25 years ago.

 

The monthly average temperature of 59.7° is just over two degrees below normal (-2.2°) and ranks as the 54th warmest March on record, tied with 1947. This is the third consecutive March that was below-normal and the first occurrence of three or more consecutive below-normal Marches since a five-March period from 1979 to 1983. Temperature extremes for the month ranged from a high of 82° on the 29th and 30th to a low of 41° on the 18th. The monthly high of 82° was cooler than the February monthly high of 86°. Since 1895, this is the 16th time on record, first since 2014, that the March monthly high was cooler than the February monthly high. The monthly low of 41° is the second warmest March monthly low on record, bested by the 46° monthly low from March 2014. This is only the seventh March on record in which the monthly low temperature was not in the 20s or 30s.

 

Rainfall amounts across the metro area, using several sources like rainlog.org, the Pima County Regional Flood Control District gages, and CoCoRaHS, ranged widely from 0.75" to 1.75 " with localized spots up to 2.50" near the mountains. The International airport, which is the official recording spot in Tucson, recorded 1.25" which ranks as the 24th wettest March on record.

The average yearly temperature of 56.5° is just under one degree BELOW normal (-0.9°) and ranks as the 30th warmest on record, tied with 1911, 1934, 1980, 2005, and 2020, through the end of March.

Rainfall at the Tucson International Airport, the official location in Tucson, of 4.41" is 2.17" ABOVE normal & ranks as the 12th wettest January through March period on record. It is the wettest first quarter of the calendar year since 2010 (4.51"). The water year rainfall is at the halfway mark with 6.35" being recorded which ranks as the 31st wettest first half of the water year period on record.

Each month so far in 2024 has recorded above-normal rainfall at the airport (January: +0.93"; February: +0.55"; March: +0.69"). This is the first time that a year, when compared to their respective normal periods, has started with three above-normal months since 1992 and it's only the 6th such occurrence since 1952.

When you add December 2023, which was 0.51" above normal, the four-straight months of above normal precipitation is the first occurrence since Summer 2006 when June through September each recorded above normal rainfall.
