Key Points:

 

December brought large swings in temperature but, overall, the average monthly temperatures in December were near to above normal across the state. Average temperature departures from normal ranged from -1.3 ̊F in Melbourne to +2.7 ̊F in Pensacola for the month (see Table 1 and Appendix 1 for select cities). The month started out warmer than normal, with record warm temperatures across the Panhandle during the first half of the month. A shift in the weather pattern brought a return to more seasonal temperatures mid-month, while the last week of December was much colder than normal. Many locations experienced frigid temperatures on the order of 20 ̊F or more below normal during the last week of December, including over Christmas. Many places in the Panhandle saw minimum temperatures in the teens, with wind chills in the single digits, including Tallahassee, which reached a low of 19 ̊ F and 18 ̊ F on the 25th and 26th, respectively; Crestview recorded a low of 18 ̊ F on the 24th; and Niceville got down to 17 ̊ F on the 24th and 25th. Select daily high maximum and low minimum temperature records tied or broken during the month are provided in Appendices 2 and 3, respectively.

Station Mean Temperature Departure from Normal
Pensacola 58.2 +2.7
Tallahassee 55.9 +1.5
Jacksonville 56.3 -0.4
Orlando 64.2 +0.9
Tampa 64.7 -0.2
Miami 72.3 +1.1
Key West 73.5 +0.5 

 

Monthly rainfall totals in December were below to near normal for much of the state. The monthly precipitation departures from normal ranged from -2.53 inches in Jacksonville to +2.02 inches in Key West (see Table 2 and Appendix 1 for additional locations). Over the past three months, below normal rainfall has led to precipitation deficits across the Panhandle and north Florida and the expansion of drought.

Station Total Rainfall Departure from Normal
Pensacola 5.61 +0.21
Tallahassee 2.09 -2.15
Jacksonville 0.25 -2.53
Orlando 0.95 -1.53
Tampa 2.35 -0.21
Miami 1.73 -0.71
Key West 4.18 +2.02

La Niña Advisory.

La Niña is expected to continue into the winter, but there are equal chances of La Niña and ENSO-neutral conditions during January-March 2023. In February-April 2023, the chance for ENSO-neutral conditions increases to 71%, reflecting higher confidence that ENSO-neutral will emerge during Spring 2023. Below-average sea surface temperatures persisted in the central and eastern Pacific Ocean over the past month, but negative subsurface temperature anomalies weakened in November 2022.

 

Hazardous Weather Events in December.

According to the Local Storm Reports issued by the local National Weather Service offices serving Florida, there were 111 individual local reports of hazardous weather events recorded across the state during the month of December (see Table 4 for a breakdown by event type). There were several reports of damage from strong wind gusts during the middle and end of the month, along with waterspouts and tornados reported in the central Panhandle area on the 14-15th.

Weather/Climate Highlight of the Month:

It was a very cold but dry Christmas across Florida – nearly every station in the state recorded one of their top 5 coldest Christmases on record, based on daily average temperatures.

 

Drought-Related Impacts.

By the middle of December, severe drought had expanded across the Panhandle and extended east to parts of Hamilton, Suwannee, and Dixie counties. About 26% of the state was in severe drought (D2) and 6% was in moderate drought (D1), according to the U.S. Drought Monitor. By the end of the month, 22% of the state was in severe drought (D2), 10% was in moderate drought (D1), and 8% was abnormally dry (D0) (Figure 2 below).

As of December 31, the Lake Okeechobee water level was 16.36 ft. above sea level (Feet-NGVD29), which is above average for this time of the year. At the first of the month, the water level was 16.48 ft. above sea level.

Agriculture-Related Impacts.

During the month of December, Florida pasture conditions were mostly fair to good but the cold spell at the end of the month led to damage to pastures across the state. There were some reports of cattle deaths due to the cold spell. Little precipitation fell during the month, which worsened drought conditions in the northern part of the state. Sugarcane planting and harvest progressed well during the month, and citrus crops not damaged by the hurricanes in the fall were shipped out. Several vegetable crops were planted and harvested. For more information, consult the Crop Progress - State Stories reports, which are produced monthly December through March by the USDA’s National Agricultural Statistics Service.
