Overview

The point forecast endpoint returns a full weather forecast for a single coordinate, extending to 180 hours. It is the general-purpose forecast product, if you need conditions at a place over the coming week, this is the endpoint.

Add include=current to get observed current conditions for the same point in the same response; it needs Observations access or a widget key, see Observations. Add include=nws_alerts (or include=current,nws_alerts) to get the National Weather Service alerts in effect there, the same as the point lookup in Alerts; it needs NWS alerts access or the weather widget product.

Air-quality and smoke forecasts are documented separately under Air Quality; agronomy-specific forecast products live under Agronomy.

Typical uses

Operational planning, scheduling, logistics routing, and any application that needs a straightforward forecast for a known location.

Coverage

High resolution across the contiguous United States and a 0.25 degree global grid everywhere else. Worldwide coverage, including the Southern Hemisphere, is rolling out; until it is enabled, points south of the equator return INVALID_LATITUDE. Open ocean is served from the global grid once worldwide coverage is enabled (until then it returns OCEAN_LOCATION_UNSUPPORTED); land-surface products such as WBGT are left out there and named in metadata.warnings. Expect lower accuracy outside the contiguous United States, especially in the Southern Hemisphere.

Heat policy zones

Add heat_policy=kshsaa to classify every WBGT value in the response against a published athletics heat policy, currently the Kansas State High School Activities Association (KSHSAA) Green to Black zones. The response gains a heat_policy object with each zone's name, color, °F bounds and activity-modification guidance, plus the zone for every forecast hour. /observations/wbgt/ takes the same parameter for the current reading.
