Seasonal forecasts

In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States

(CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular season. According to NOAA and CSU, the average hurricane season between 1991 and 2020 contained about 14 named storms, 7 hurricanes, and 3 major hurricanes (Category 3 and higher), as well as an

multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.

Pre-season forecasts

On April 3, 2025, Colorado State University (CSU) released its forecast, which predicts an above-average hurricane season with 17 named storms, 9 hurricanes, and 4 major hurricanes, with an ACE index of 155, citing extremely warm Atlantic sea surface temperatures and a weakening

Season effects

The following is a table which will include all of the storms that form in the 2025 Atlantic hurricane season. It will include their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.
