Phase vs Phase, 1950-2025 (ONI coverage)
ENSO Laboratory
Head-to-head comparison of the three ENSO phases across every hurricane season from 1950 to 2025. Raw counts alone mislead when the phases occur unequally often, so each column also shows how many total seasons that phase produced, and the share that brought Florida a hurricane. Storms before 1950 predate the ONI record and are listed in the Timeline without a phase.
