September 2025 in Review - For the Mobile area, high temperatures were just a bit above normal for the month while Pensacola area highs were closer to September normal about the means. For lows, the temperature trace about the means were very close at both the Mobile and Pensacola areas. At Mobile, lows were at or below normal for the beginning two thirds of the month, averaging 3.7° below normal for the period from the 1st to the 20th and at Pensacola, averaging 3.0° below normal for the same period. Morning lows showed moderation (warming) about the means the remainder of the month, averaging 2.5° above normal at Mobile and at Pensacola, 2.3° above normal. There were no record temperatures set at Mobile and Pensacola.
Unfortunately, September was unusually dry with the lack of rainfall resulting in a return of drought to close out the month. There was considerable time where the lack of rain was hanging tough in the top five driest September's on record until a late month weather system changed that. Even so, the rain gauge at both Mobile and Pensacola settled at a few inches below typical September normal.
Mobile Alabama Area [Climate Normal Period 1991-2020, Climate Record Period 1872 to Present]- The average monthly high of 90.1° was 2.6° above normal. The average monthly low was 67.2° or 1.6° below normal. The average monthly temperature of 78.6° was 0.5° above normal. The highest temperature for the month was 94° on the 20th or 7° above the normal for the date. The lowest temperature for the month was a cool 62° on the 8th, 9.0° below normal for this date. (Fig. A) shows a graphical representation of how the Mobile area temperatures compared to the seasonal normal daily highs and lows, which are shown by the colored dashed lines. Bar graphs reflecting the daily high/low temperature departures from normal are provided in the table below (Figs. B and C). Just a little over an inch of rain for the whole month was captured in the rain gauge, measuring 1.33" (Fig. D), 3.97" below the monthly normal. With the last several months leading up to September enjoying an annual rainfall surplus, the lack of rainfall in September has erased those. Mobile's annual rainfall at 52.41" is moved into deficit territory by a little over a half inch at 0.67" below the normal.(Fig. E). Overall though, when considering the grand scheme when looking at the bigger picture of accumulated annual rainfall to date, Mobile is close to normal to close out September.

Pensacola Florida Area [Climate Normal Period 1991-2020, Climate Record Period 1879 to Present] - The average monthly high of 88.8° was 0.3° above normal. The average monthly low was 70.4° or 1.1° below normal. The average monthly temperature of 79.6° was 0.4° below normal. The highest temperature for the month was 92°, occurring on the 12th, 19th, 20th, and the 28th or 4.3° above the normal on average for these dates. The lowest temperature for the month was 66° on the 8th and 11th, 7.0° below normal for these days. (Fig. F) shows a graphical representation of how the Pensacola area temperatures compared to the seasonal normal daily highs and lows, which are shown by the colored dashed lines. (Figs. G and H) shows the daily high/low temperature departures from normal. Only 2.00" of rain for the month at Pensacola and 4.61" below the monthly normal (Fig. I) has caused the annual rainfall amount to date of 48.41" to tumble to 5.38" below normal (Fig. J).

Additional September 2025 Climatology and Topics
The lack of rainfall was quite noticeable for the month of September over the central Gulf coast with areas primarily along and southeast of I-65 seeing deficits some three to over five inches below normal for the month. A large area saw 25 to 50% of normal September rains and within that, there were several areas seeing 5 to 10% of normal. Very Dry indeed!!!. (Fig. K) shows the areal distribution of monthly rainfall, (Fig. L) shows the areal rainfall departures from normal and (Fig. M) percent of normal rains. We entered the month of September with abnormal dryness and pockets of moderate drought over portions of the interior, expanding area-wide and even worsening in a few areas over the interior by the end of the month (Fig. N). With September being the typical peak in the Atlantic Basin Hurricane Season, September 2025 was quite the opposite. The quietest peak in decades materialized with no named storms from August 28th to September 15th, a lull not seen since 1939. Factors contributing to zero activity during this time-frame were:
The Atlantic Basin eventually became more active with Hurricanes Gabrielle, Humberto, and Imelda forming the latter half of the month. (Fig. O).

October 2025 Climatology, Seasonal Climatology and Outlooks:
Looking ahead to one of our typically drier months, October temperatures are favored to lean above normal over the deep south. Equal chances of above or below normal precipitation is favored over the southeast U.S. and leaning below normal from the New England States, southwest to across Texas. There are indications that drought could linger over the deep south through the end of the year. Although we have moved out of the climatological peak of hurricane season, take note that October does see a climatological spike in tropical cyclone occurrences with the points of origin typically from the northwest Caribbean, Gulf and off the southeast US coast.

Additional Climate Links:
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.
