New York NYSPHSAA Heat Rules

New York is the state that shows WBGT is a choice, not a law of nature. Its procedure is written against heat index, and it tells schools to read that number from a phone app by ZIP code — the exact thing Georgia, South Carolina and Iowa warn against.

This is a heat index policy

The procedure checks "Feels Like" temperature — heat index — 1 hour before the contest or practice whenever air temperature is 80 °F or higher. A WBGT indicator is offered as an alternative, but heat index is the ladder the thresholds are written for.

New York names an app

In writing: "Download WeatherBug app to your phone or log into www.weatherbug.com." and "Enter zip code or city and state in the location section of the app or on-line or determine the THI by using a Wet Bulb Globe Temperature Indicator." A remote, ZIP-code-level reading is not a workaround in New York — it is the documented procedure.

That does not make a remote reading physically accurate; it makes it permitted. Everything this site says about remote estimates reading low still applies, and a heat index number cannot be compared against a WBGT threshold in either direction.

Heat index thresholds (°F)

Feels Like temp (heat index)	Tier	Action
under 79 degrees	Full activity — Recommended	Full activity. No restrictions.
80 degrees to 85 degrees	Heat Index Caution — Recommended	Provide ample water and multiple water breaks; monitor athletes for heat illness. Consider reducing the length of the practice session.
86 degrees to 90 degrees	Heat Index Watch — Recommended	Provide ample water and multiple water breaks; monitor athletes for heat illness. Consider postponing practice to a time when the Feels Like temperature is lower. One hour of recovery time for every hour of practice.
91 degrees to 95 degrees	Heat Index Warning — Recommended	Provide ample water and water breaks every 15 minutes. Light weight, loose fitting clothes should be worn. For practices, football helmets only — no other protective equipment. One hour of recovery time for every hour of practice.
96 degrees or greater	Heat Index Alert — Required	No outside activity, practice or contest, should be held. Indoor activity only if air conditioned.

New York does publish a WBGT alternative chart, but its thresholds depend on a regional category looked up from an external map, and the chart itself was not machine-readable in the source document. This site does not reproduce New York WBGT numbers rather than risk printing the wrong region's.
