What is ACE? (tap to expand)

Accumulated Cyclone Energy (ACE) measures total hurricane season activity by combining storm intensity and duration. A major hurricane that lasts two weeks contributes far more than a brief tropical storm. NOAA uses seasonal ACE totals to classify years as Below Normal (<73), Near Normal (73–126), Above Normal (126–159), or Extremely Active (159+).

Data Sources

ACE (Accumulated Cyclone Energy) is calculated at 6-hourly synoptic times (0000/0600/1200/1800 UTC) for systems with status TS, HU, or SS and wind β‰₯34 kt β€” extratropical (EX) phases are excluded per NHC methodology. Formula: ACE = Ξ£(VΒ²max) Γ— 10⁻⁴. Categories use the Saffir-Simpson scale in knots.

Basin note: The East & Central Pacific tab combines both the Eastern Pacific (NHC, east of 140Β°W) and Central Pacific (CPHC, 140Β°W–180Β°) basins, consistent with the NOAA HURDAT2 Northeast & North Central Pacific dataset. NHC tracks these separately on their TCR pages (epac / cpac).

⚠️ This site is maintained by a hurricane data enthusiast β€” not a meteorologist, forecaster, or weather professional of any kind. I just love the data. All information is sourced directly from official NOAA/NHC databases. For official forecasts, watches, warnings, and life-safety information, always refer to the National Hurricane Center.
