2025 Fall Weather Forecast: Expect Cooler Temperatures, Fewer Hurricanes with La Niña Influence

Fall Weather Outlook: Cool Start for East, Lingering Heat in West, and Rising Hurricane Threat

As August draws to a close, a dramatic change in weather is unfolding across the nation. Residents from the Eastern United States to the West Coast are experiencing vastly different conditions. The forecast calls for an early taste of fall in the East, continued warmth in the West, and a heightened awareness of potential hurricane activity.

East coast chill: A Prolonged Cool Spell

Many in the eastern half of the country are questioning if the recent cool weather-which saw temperatures dip into the 20s in parts of West Virginia on August 26-signals an end to summer. Forecasters confirm that chilly conditions are expected to persist in the short term.

A high-pressure system moving from Canada into the Northeast will dominate the region through the Labor Day holiday. This system promises comfortable days with sunshine, but will also bring noticeably cool nights. Temperatures are trending 15 degrees below historical averages, with near-record lows anticipated, with highs in the 60s and 70s, and lows falling into the 40s and 50s.

The National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Centre echoes this outlook, stating that early September forecasts favor below-normal temperatures across much of the Midwest and East.

When Does Fall Officially Begin?

Meteorologists recognize September 1st as the start of meteorological fall, aligning with the calendar. Though, the astronomical fall-marked by the autumnal equinox-arrives on September 22nd this year. This occurs when the sun aligns directly with the equator, resulting in roughly equal hours of daylight and darkness.

West and Florida: holding onto Summer

While the East shivers, residents of florida and the western United States can expect continued summer-like temperatures throughout much of september. Unusually warm temperatures are predicted for the Northwest, with highs potentially reaching 100 degrees east of the Cascade Mountains.

Eastward warmth is on the Horizon

Despite the current cool spell, forecasters anticipate a return to above-average temperatures in the East by mid-September. The Climate Prediction Center also supports this prediction, forecasting above-normal temperatures for much of the lower 48 throughout September.

Though, extreme summertime heat of 95 degrees or higher is not expected to return this season in the East.

Drought Concerns and Hurricane Season outlook

A developing concern is the lack of rainfall in the Northeast, which has contributed to a growing drought in New England. This drought is expected to worsen before tropical moisture arrives later in the month.

Looking ahead, meteorologists predict an increase in tropical activity in the Atlantic Basin during the remainder of the hurricane season. Following a temporary lull, the threat of tropical cyclones is expected to return by the second half of September and extend through October and November.

The Influence of La Niña

The potential development of La Niña-characterized by cooler-than-average sea surface temperatures in the Pacific Ocean-could further influence the hurricane season. La Niña conditions are associated with a doubling of hurricane activity in November compared to neutral or El Niño conditions.

Beyond hurricanes, La Niña typically brings cooler temperatures to the northern United States and diminished storm activity across the southern tier, resulting in milder temperatures and reduced precipitation. Conversely, it can shift the storm track northward, increasing precipitation in the Ohio Valley and Great Lakes regions.

However, the current La Niña development is predicted to be weak and short-lived, which may lessen its impacts.

Regional Fall Weather Outlook

Region	Temperature Trend (Early September)	Precipitation Outlook	Hurricane Risk
Eastern US	Below Normal – chilly	Normal	Moderate
western US	Above Normal – Warm	Normal	Low
Florida	Above Normal – Warm	Normal	Moderate to High
New England	Below Normal – Chilly	Below Normal (Drought Conditions)	Moderate

Did You No? The autumnal equinox, marking the start of astronomical fall, occurs when the sun crosses the celestial equator, resulting in nearly equal day and night lengths globally.

Pro Tip: Prepare for potential temperature swings by layering clothing. Staying informed about local weather alerts is also essential, particularly as hurricane season intensifies.

What are your preparations for the changing seasons? Will you adjust your plans based on these forecasts?

understanding seasonal weather patterns is crucial for preparedness. Monitoring long-range forecasts from NOAA and AccuWeather can help individuals and communities plan effectively for potential impacts, such as drought conditions or hurricane threats.

the interplay between global climate patterns like La Niña and regional weather conditions highlights the interconnectedness of the Earth’s climate system. Staying informed about these patterns not only helps with short-term planning but also fosters a broader awareness of climate change trends.

Understanding the La Niña Impact on Fall 2025

The dominant climate pattern influencing this year’s fall weather is La Niña. This climate phenomenon, characterized by unusually cold ocean temperatures in the central and eastern tropical Pacific Ocean, is expected to strengthen throughout the fall season. Unlike it’s counterpart, El Niño, La Niña typically brings distinct weather changes, particularly impacting temperature and hurricane activity. Expect a noticeable shift from recent warmer trends. This fall forecast focuses on the implications of La Niña for the continental United states, offering insights into regional variations and potential impacts.

Cooler Temperatures Across the Nation

One of the most important effects of La Niña this fall will be cooler-than-average temperatures across much of the United States.

Northern Tier: States from the Pacific Northwest through the Great Lakes and into New England are predicted to experience the most significant temperature drops. Early snowfall is a possibility in some areas.

Plains & Midwest: Below-average temperatures are also anticipated in the plains and Midwest, perhaps impacting agricultural yields and heating costs.

South: While the South will likely see temperatures closer to average, expect more frequent cold snaps and a generally milder fall compared to recent years.

West Coast: The Pacific Northwest will experience cooler, wetter conditions, while California may see a slightly drier fall.

These temperature predictions are based on long-range forecasting models and historical La Niña patterns. Monitoring daily and weekly forecasts remains crucial for accurate planning. consider seasonal temperature outlooks from the National Weather Service for detailed regional data.

Reduced Hurricane Activity in the Atlantic

La Niña typically suppresses hurricane activity in the Atlantic basin. Increased wind shear – changes in wind speed and direction with altitude – disrupts the formation of tropical cyclones.

Fewer Named Storms: Forecasters predict a below-average hurricane season for the remainder of 2025.

Reduced Major Hurricane Risk: The likelihood of a major hurricane (Category 3 or higher) making landfall in the United States is significantly lower than in recent years.

Gulf Coast & East Coast: While the risk is reduced, coastal communities should remain vigilant and prepared. Even a less active season can produce impactful storms.

Though, it’s significant to remember that even a less active hurricane season can still produce impactful storms. Staying informed through the national Hurricane Centre is vital.
