September 2021 in Review - Overall, September turned out to be slightly cooler than normal. Contributing to this was a couple of periods where highs and lows dipped to well below climatology. On the 15th, the thermometer struggled to get into the mid 70s at Mobile which resulted in a record low high temperature being tied and also 12° below normal. To close out the month, highs averaged 4.9° below normal. At Pensacola, highs averaged 5.3° below normal spanning the 13th through the 19th then closing out the month from the 22nd to the 30th a couple degrees below normal. The 9th through 11th, lows averaged 7.6° and 6° below normal at Mobile and Pensacola respectively. Later in the month, a more substantial six morning stretch from the 22nd to the 27th was even cooler, with lows that period averaging 10° and 6.8° below normal at Mobile and Pensacola respectively.
Above normal rainfall at both Mobile and Pensacola continued to add to the annual surplus.
Mobile Alabama Area [Climate Normal Period 1991-2020, Climate Record Period 1872 to Present]- The average monthly high of 84.6° was 2.9° below normal. The average monthly low was 67.8° or 1.0° below normal. The average monthly temperature of 76.2° was 1.9° below normal. The highest temperature for the month, 93° occurred on the 1st day of the month, 3° above the normal for the date.

A record low high temperature was reached on the 15th; 76° tied the previous record set on this date way back in 1913.

October 2021 Climatology, Seasonal Climatology and Outlooks:
The latest outlook for October shifts from the wetter and cooler conditions we saw in September to a pattern favoring warmer and potentially drier conditions. The latest forecast calls for above normal temperatures over the deep south and equal chances of seeing below or above normal precipitation. Despite warmer weather being favored, the period of record indicates that some of the earliest onset dates of freezing weather have occurred over the Gulf coast in October. The earliest freeze dates are provided in the table below. Although the peak of hurricane season has passed, it by no means suggests an end to the season. October can be a busy month for tropical storms and/or hurricanes. It's highly encouraged to review your hurricane preparedness. Click on the Preparedness Tab on the NWS Mobile Tropical Webpage.

Additional Climate Links:
The links below are intended to provide additional climate information, education and outlooks. The National Weather Service Mobile Alabama's Climate and Past Weather page provides climate data at your fingertips for many observation points in the local forecast area by accessing the NOWData tab as well as many other climate resources. The Climate Prediction Center Link provides short and longer range climatic outlooks and education about the larger scale global circulations that impact temperatures and weather. With the large agriculture and farming presence along the central Gulf coast, the Drought Monitor link provides updates on drought trends and impacts. Another very helpful resource is the Community Collaborative Rain Hail and Snow (CoCoRaHS) network, which is a large group of volunteers working together to measure and map precipitation (rain, hail and snow). The aim of CoCoRaHS is to provide the highest quality data for natural resource, education and research applications. You can be a part of the CoCoRaHS team by becoming a volunteer rainfall observer.
