Hurricane ACE DashboardAccumulated 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 (73β126), Above Normal (126β159), or Extremely Active (159+).
No named storms yet β the 2026 season is underway but quiet so far.

Formula: ACE = Ξ£(VΒ²max) Γ 10β»β΄. 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°Wβ180Β°) basins, consistent with the NOAA HURDAT2 Northeast & North Central Pacific dataset. NHC tracks these separately on their TCR pages (epac / cpac).
