2025 Atlantic Hurricane Season Forecast: Increased Activity Expected

The Atlantic hurricane season officially spans from June 1 to November 30 each year, with a long-term average of about 14 named storms, 7 hurricanes, and 3 major hurricanes based on the past three decades. However, climate experts caution that 2025 may exceed these averages, reflecting or surpassing recent seasons that have seen multiple high-intensity cyclones.

A key factor in seasonal forecasting is the El Niño–Southern Oscillation (ENSO). During an El Niño phase, the waters of the Pacific Ocean near the equator warm significantly, which typically leads to increased wind shear over parts of the Atlantic. This wind shear can disrupt the formation of storms, reducing their frequency and intensity. Conversely, a neutral or weak La Niña pattern results in lower wind shear in the Atlantic, facilitating the formation and intensification of storms.

Colorado State University (CSU) predicts only a 13 % chance of El Niño conditions developing by the peak season (August-October), suggesting that wind shear is likely to remain moderate and the ocean environment will be conducive to hurricane development.

CSU’s tropical cyclones team forecasts:

• 17 named storms;
• 9 hurricanes;
• 4 major hurricanes (Category 3 or higher).

They estimate a 51 % chance of a major hurricane making landfall in the US, compared to a historical average of 43 %.

AccuWeather projects:

• 13 to 18 named storms;
• 7 to 10 hurricanes;
• 3 to 5 major hurricanes;
• 3 to 6 potential direct impacts on the US.

While these estimates vary slightly in the total number of storms, both sources agree that conditions are favorable for potentially explosive cyclones. Warm ocean waters across the Atlantic, Caribbean, and Gulf could accelerate storm development, making it crucial for coastal residents and maritime operators to stay alert.

How Accurate Are Forecasts? A Review of the 2024 Hurricane Season

Initial predictions for the 2024 Atlantic hurricane season indicated an extremely active year, with some forecasts suggesting 20 to 25 named storms and multiple major hurricanes. Ultimately, 18 named storms formed, which was a slight decrease from early expectations. However, the season compensated for its lower quantity with several powerful hurricanes that collectively caused an estimated $200 billion in damages.

Hurricane Beryl made headlines by forming unusually early in the first week of June, defying typical seasonal patterns where the strongest storms usually occur between August and October. Beryl’s rapid transition to hurricane status surprised many, demonstrating how ocean heat can fuel storm growth earlier in the season than anticipated. Although Beryl’s winds primarily remained offshore, it caused heavy rainfall and coastal flooding in the Windward Islands.

Despite Beryl’s early impact, late August into early September brought a period of calm—one of the quietest stretches recorded during what is typically the peak of hurricane season. This led some to mistakenly believe the season might end quietly, but the lull was more of a temporary reprieve than an indication of what was to follow.

Hurricane Helene (September 24-27)

Hurricane Helene developed shortly after the 2024 season’s quiet phase, rapidly becoming a Category 4 storm within days. Making landfall along the Southeastern US coast in early September, Helene unleashed severe flooding, powerful winds, and even tornado outbreaks far inland, ultimately becoming one of the deadliest hurricanes in modern US history.

Tragically, Helene claimed at least 250 lives, primarily due to inland flash floods and storm surges in low-lying areas.

Hurricane Milton (October 5-10)

As the season neared its typical conclusion, Hurricane Milton formed in the Gulf of Mexico and quickly intensified in under 36 hours. Milton’s landfall in Florida resulted in widespread flooding and over 30 tornadoes, devastating communities still recovering from Helene’s effects.

Evacuations saved lives, but property damage escalated, adding to the cumulative costs of the 2024 season.

Why These Predictions Matter

Every hurricane season presents challenges, but the outlook for 2025 is particularly concerning due to persistently warm waters and minimal wind shear. These conditions can significantly impact offshore facilities, ports, and cargo fleets.

The Gulf of Mexico and deep tropics may remain warm well into the fall, allowing hurricanes to intensify rapidly. Changing atmospheric patterns could also steer storms into areas historically considered lower risk. As seen in 2024, multiple back-to-back hurricanes could overwhelm response teams and hinder rescue efforts.

Coastal regions and maritime workers face these risks directly. Crews on fixed platforms, jack-up rigs, drillships, commercial fishing vessels, and large cargo ships, as well as dock and harbor workers, may find themselves in harm’s way.

Looking Ahead

For 2025, both CSU and AccuWeather expect conditions that favor at least an average (and likely above-average) number of strong storms. Even a moderate total storm count could result in multiple hurricanes of Category 3 or higher, posing significant threats to offshore operations, maritime workers, and coastal communities.

When it comes to Atlantic storms, preparation remains the best defense. Maritime employers can better protect their employees, assets, and the environment by utilizing technological advancements in storm prediction, implementing thorough emergency protocols, and aligning operational decisions with the latest meteorological data.

Ultimately, it only takes one direct hit from a powerful hurricane to reshape the narrative of an entire season.
