Historical Weather Data for September

September typically marks the transition from summer to autumn in the Northern Hemisphere. Analyzing past weather patterns can provide valuable clues about what to expect in September 2025.

Average Temperatures

Across the United States, average temperatures in September vary significantly depending on the region. For example:

• Northeast: Expect average highs in the low 70s (°F) and lows in the mid-50s (°F).
• Southeast: Temperatures are generally warmer, with highs in the upper 80s (°F) and lows in the low 70s (°F).
• Midwest: Look for average highs in the low 70s (°F) and lows in the mid-50s (°F).
• Southwest: This region remains hot, with average highs in the low 90s (°F) and lows in the upper 60s (°F).
• Pacific Northwest: Expect milder temperatures, with highs in the mid-60s (°F) and lows in the low 50s (°F).

These averages are based on historical data from the National Oceanic and Atmospheric Administration (NOAA) and serve as a general guideline. Actual temperatures in September 2025 may fluctuate. — Kerrville TX Weather Radar: Live Local Updates

Rainfall Expectations

Rainfall in September also varies by region. Here’s a general overview:

• Northeast: September is typically a relatively dry month, with average rainfall ranging from 3 to 4 inches.
• Southeast: Expect higher rainfall, especially in coastal areas, with averages between 4 and 6 inches due to potential tropical storms.
• Midwest: Rainfall is moderate, averaging around 3 to 4 inches.
• Southwest: September is generally dry, with minimal rainfall, often less than 1 inch.
• Pacific Northwest: Rainfall begins to increase in September as the region transitions into its wet season, with averages between 2 and 4 inches.

Rainfall data is sourced from NOAA's historical records, providing a reliable baseline for expectations. Keep in mind that these are averages, and specific rainfall amounts can differ. — YouTube Down? Here's What To Do

Potential for Extreme Weather

September is still within the Atlantic hurricane season, which runs from June 1 to November 30. Coastal regions, particularly in the Southeast, should remain vigilant for potential tropical storms and hurricanes. According to FEMA, it's crucial to have an emergency plan in place.

In other regions, extreme weather events are less common in September, but heatwaves can still occur, especially in the Southwest. Stay informed about local weather forecasts and heed any warnings issued by local authorities.

Factors Influencing September 2025 Weather

Several factors can influence the weather patterns in September 2025. These include long-term climate trends, El Niño-Southern Oscillation (ENSO) patterns, and other atmospheric conditions.

Long-Term Climate Trends

Climate change is causing shifts in weather patterns worldwide. Rising global temperatures can lead to more extreme weather events, such as heatwaves, droughts, and intense rainfall. According to the Environmental Protection Agency (EPA), monitoring these long-term trends is essential for understanding future weather patterns.

In our analysis, we've observed that average temperatures in September have been gradually increasing over the past few decades. This trend suggests that September 2025 could be warmer than historical averages.

El Niño-Southern Oscillation (ENSO)

ENSO is a climate pattern that affects weather conditions across the globe. It has three phases: El Niño, La Niña, and Neutral. El Niño typically leads to warmer and drier conditions in the northern United States, while La Niña often results in cooler and wetter conditions.

As of now, it’s too early to predict the ENSO phase for September 2025. However, monitoring ENSO conditions in the months leading up to September will provide valuable insights into potential weather patterns. The National Weather Service provides regular updates on ENSO conditions.

Other Atmospheric Conditions

Other atmospheric conditions, such as the North Atlantic Oscillation (NAO) and the Pacific Decadal Oscillation (PDO), can also influence weather patterns. These oscillations affect air pressure and sea surface temperatures, which in turn impact weather conditions.

For example, a positive NAO phase typically leads to warmer and drier conditions in the eastern United States, while a negative phase can result in cooler and wetter conditions. These factors interact in complex ways, making long-term weather prediction challenging.

Regional Weather Predictions for September 2025

While a precise forecast is impossible this far in advance, we can offer some speculative regional predictions based on current climate models and historical data.

Northeast

Expect average temperatures slightly above historical norms, with highs in the mid-70s (°F) and lows in the upper 50s (°F). Rainfall is likely to be near average, with a possibility of occasional showers. The Farmer's Almanac suggests keeping an eye out for early signs of fall foliage.

Southeast

Temperatures are expected to be warmer than average, with highs in the low 90s (°F) and lows in the mid-70s (°F). Rainfall could be higher than average due to the ongoing hurricane season. Residents should stay prepared for potential tropical storms and hurricanes.

Midwest

Look for average temperatures in the low 70s (°F) and lows in the mid-50s (°F), similar to historical norms. Rainfall is expected to be average, with periods of dry weather and occasional thunderstorms. Agricultural forecasts will be particularly important for farmers in this region.

Southwest

Expect continued hot weather, with average highs in the mid-90s (°F) and lows in the low 70s (°F). Rainfall is likely to be minimal. Water conservation efforts will remain critical in this region.

Pacific Northwest

Temperatures are expected to be near average, with highs in the upper 60s (°F) and lows in the mid-50s (°F). Rainfall is likely to be slightly above average as the region transitions into its wet season. Outdoor enthusiasts should prepare for cooler and wetter conditions.

How to Prepare for September 2025 Weather

Regardless of the specific weather conditions in September 2025, there are several steps you can take to prepare:

• Stay Informed: Monitor weather forecasts regularly from reputable sources like the National Weather Service.
• Emergency Preparedness: Have an emergency plan in place, especially if you live in an area prone to hurricanes or other extreme weather events. Ready.gov offers comprehensive resources for emergency preparedness.
• Pack Accordingly: Pack a variety of clothing to accommodate potential temperature fluctuations. Layering is a good strategy.
• Home Maintenance: Ensure your home is properly maintained to withstand potential weather events. Check your roof, gutters, and drainage systems.
