NOAA records little property damage for this hazard — its toll is in lives and health, not property. Absence of a damage figure is not absence of harm.

Read this as one year, not history. These are NOAA's 2025 figures — a single, volatile year (a major event in another year would change them sharply). Deaths are NOAA "direct" deaths only — and for heat this is the tip of the iceberg: most heat deaths are recorded as indirect (heart attacks, organ failure) and are excluded here and widely undercounted, so the real toll is far higher.

Where heat took the most lives in 2025

Highest recorded direct-death toll by state. This reflects 2025 events, not a state's standing risk.

What these figures mean

RECORDED — the death, injury, and damage counts are NOAA Storm Events records of 2025 events, summed across states.
CONTEXT — one volatile year; direct deaths only; damage is NOAA's estimate, not insured loss. Past toll is not a forecast of your risk.

This is the past toll — not your risk
