Hurricane statistics show why storm counts alone are not enough: the 2024 North Atlantic season had 18 named storms, 11 hurricanes and 5 major hurricanes, while impacts varied sharply by storm. The figures below define the measures, periods and geographies so activity, intensity, energy, deaths and damage are not treated as interchangeable.
Key Hurricane Statistics
The most useful headline figures from the 2024 Atlantic season and its historical context are:
- 18 named storms formed in the North Atlantic during the 2024 season.

2024 Atlantic Hurricane Activity and Historical Averages
The National Hurricane Center’s 2024 Atlantic summary distinguishes three thresholds. Tropical storms have maximum sustained winds of 34–63 kt, hurricanes have at least 64 kt, and major hurricanes have at least 96 kt, equivalent to Category 3 or higher in the Saffir-Simpson scale.
| Measure | 2024 Atlantic season | 1991–2020 average |
|---|---|---|
| Named storms | 18 | 14 per season |
| Hurricanes | 11 | 7 per season |
| Major hurricanes | 5 | 3 per season |
| ACE | 161.5 | 32% below 2024 level in NHC comparison |
The 2024 counts and climatological averages come from the National Hurricane Center’s 2024 Atlantic Hurricane Season summary. The averages are a 30-year climatology, not a forecast for an individual season, and ACE is an intensity-duration index rather than a damage measure.
The season’s 18 named storms therefore included 11 that reached hurricane strength and 5 that reached major-hurricane strength. Those categories describe maximum sustained wind thresholds, not the number of people affected or the cost of losses.
2024 Hurricane Intensity Statistics: Wind and Pressure
The 2024 post-season best track records maximum sustained wind in knots and minimum central pressure in millibars. Lower pressure often accompanies a stronger cyclone, but wind and pressure are separate observations and should not be read as identical measures.
| Storm | Dates in 2024 | Maximum wind | Minimum pressure |
|---|---|---|---|
| Beryl | June 28–July 9 | 145 kt | 932 mb |
| Debby | August 3–8 | 70 kt | 979 mb |
| Ernesto | August 12–20 | 85 kt | 967 mb |
| Francine | September 9–12 | 90 kt | 972 mb |
| Helene | September 24–27 | 120 kt | 939 mb |
| Isaac | September 25–30 | 90 kt | 963 mb |
| Kirk | September 29–October 7 | 130 kt | 928 mb |
| Leslie | October 2–12 | 90 kt | 970 mb |
| Milton | October 5–10 | 155 kt | 895 mb |
| Rafael | November 4–10 | 105 kt | 954 mb |
These storm-level wind and pressure values are from the NHC 2024 Atlantic season summary, which identifies them as post-season best-track maximum and minimum values. Milton’s 895 mb minimum was below 900 mb, while Beryl reached 145 kt and Kirk reached 130 kt.
Accumulated Cyclone Energy Statistics by 2024 Storm
Accumulated Cyclone Energy, or ACE, sums six-hourly squared maximum sustained winds while a system is at least tropical-storm strength. It captures both intensity and duration, so it is useful for comparing seasonal or storm energy, but it is not a direct estimate of risk, damage or deaths.
| Storm | Dates | ACE (10^4 kt^2) |
|---|---|---|
| Beryl | June 28–July 9 | 34.5 |
| Debby | August 3–8 | 4.9 |
| Ernesto | August 12–20 | 14.4 |
| Francine | September 9–12 | 4.8 |
| Helene | September 24–27 | 7.0 |
| Isaac | September 25–30 | 7.9 |
| Kirk | September 29–October 7 | 23.7 |
| Leslie | October 2–12 | 16.1 |
| Milton | October 5–10 | 22.5 |
| Rafael | November 4–10 | 12.3 |
| Oscar | October 19–22 | 4.5 |
| Sara | November 14–18 | 2.0 |
The storm values and the season total of 161.5 ACE units are reported by the NHC 2024 Atlantic Hurricane Season summary. The NHC comparison places 2024 ACE 32% above the 1991–2020 normal, but that comparison does not convert energy into losses.
Hurricane Deaths and U.S. Damage Statistics in 2024
The NHC’s direct-death definition includes storm surge, rough seas, rip currents, freshwater floods, lightning and wind-related events. Its damage figures are NCEI-based U.S.-only estimates in 2024 dollars, so they do not represent worldwide losses.
| Storm | Dates | Direct deaths | U.S. damage |
|---|---|---|---|
| Beryl | June 28–July 9 | 35 | $7.2 billion |
| Debby | August 3–8 | 12 | $2.5 billion |
| Ernesto | August 12–20 | 3 | No reported U.S. damage |
| Francine | September 9–12 | 0 | $1.3 billion |
| Helene | September 24–27 | 175 | $78.7 billion |
| Milton | October 5–10 | 15 | $34.3 billion |
| Rafael | November 4–10 | 2 | No reported U.S. damage |
| Oscar | October 19–22 | 8 | No reported U.S. damage |
| Sara | November 14–18 | 9 | No reported U.S. damage |
The storm estimates and observations are from the NHC 2024 Atlantic season summary. “No reported U.S. damage” means the NHC table reported no U.S. damage value; it does not prove that damage outside the United States was zero.
Across the full 2024 North Atlantic season, NHC recorded 273 direct deaths and $124.125 billion in U.S. damage. The full-season totals and storm-level figures use different kinds of measurement—direct mortality and U.S.-only economic loss—so neither should be inferred from ACE alone.
Long-Term Atlantic Hurricane Trends and U.S. Landfalls
The revised HURDAT record helps compare seasons, but historical rows can change as reanalysis updates. Its season-level counts also differ from the broader question of how many Atlantic storms existed because U.S. hurricane figures count impacts or landfalls in the continental United States.
| Season | Named storms | Hurricanes | Major hurricanes | U.S. hurricanes |
|---|---|---|---|---|
| 2005 | 28 | 15 | 7 | 6 |
| 2010 | 19 | 12 | 5 | Not supplied |
| 2013 | 14 | 2 | 0 | Not supplied |
| 2020 | 30 | 14 | 7 | 6 |
| 2024 | Not listed in this HURDAT row comparison | Not listed in this HURDAT row comparison | Not listed in this HURDAT row comparison | 5 |
The historical comparisons are from NOAA/AOML’s HURDAT comparison table. The 2013 season illustrates why named-storm counts alone can mislead: it had 14 named storms but only 2 hurricanes and no major hurricanes.
The HURDAT comparison lists 161 ACE units for 2024, rounded to a whole number, while the NHC summary reports 161.5. NOAA’s table lists 5 U.S. hurricanes for 2024 and 6 for both 2005 and 2020; the table’s U.S. hurricane column is not a count of every Atlantic storm.
Hurricane Records, Seasonal Timing and Recent Trends
NOAA’s season wrap-up reports five storms making continental-U.S. landfall in 2024, including two major hurricanes. That landfall count is narrower than a storm-impact count because it refers specifically to continental-U.S. landfall.
Beryl was the earliest Atlantic Category 5 hurricane recorded in a season. NOAA also reported that 2024 was the first Atlantic season since 2019 with multiple Category 5 hurricanes, using Category 5’s threshold of at least 137 kt.
Milton reached a minimum pressure below 900 mb, making it the first Atlantic hurricane since Wilma to do so. These record statements describe timing or pressure in the Atlantic best-track context, not the total damage caused by the storm.
The record and landfall context comes from NOAA NESDIS’s 2024 Atlantic Hurricane Season Wraps Up.
A peer-reviewed analysis described an unusual mid-season lull. Between August 20 and September 23, 2024, the Atlantic generated about 7 ACE units, compared with about 54% of seasonal ACE typically occurring in that interval under the 1991–2020 climatology.
From September 24 through the end of 2024, 11 named storms, 7 hurricanes and 4 major hurricanes formed. The same study reported that September 2024 Main Development Region sea-surface temperature was about 1.0°C above the 1991–2020 average.
The interval comparisons and regional anomaly appear in the peer-reviewed The Remarkable 2024 North Atlantic Mid-Season Hurricane Lull. They are descriptive statistics, not proof that one measured environmental factor caused the season’s outcome.
