Error getting zone fire forecast from zone ID

[danielg7]

I'm trying to programmatically get the zone fire weather forecast for a given lat / lon.

I'm able to get the fire weather zone through there:

Input:
https://api.weather.gov/zones?type=fire&point=40.5852%2C-105.0844&include_geometry=false
Output:

{ "@context": { "@version": "1.1" }, "type": "FeatureCollection", "features": [ { "id": "https://api.weather.gov/zones/fire/COZ238", "type": "Feature", "geometry": null, "properties": { "@id": "https://api.weather.gov/zones/fire/COZ238", "@type": "wx:Zone", "id": "COZ238", "type": "fire", "name": "Larimer County Below 6000 Feet/Northwest Weld County", "effectiveDate": "2024-03-05T18:00:00+00:00", "expirationDate": "2200-01-01T00:00:00+00:00", "state": "CO", "forecastOffice": "https://api.weather.gov/offices/BOU", "gridIdentifier": "BOU", "awipsLocationIdentifier": "BOU", "cwa": [ "BOU" ], "forecastOffices": [ "https://api.weather.gov/offices/BOU" ], "timeZone": [ "America/Denver" ], "observationStations": [], "radarStation": null } } ] }

So my zone ID is: COZ238

If I go here: https://api.weather.gov/zones/fire/COZ238 I get the geometry of the zone. That's great but not the forecast.

If I go here: https://api.weather.gov/zones/fire/COZ238/forecast/
I get an error telling me the zone doesn't exist:

{ "correlationId": "17515f95", "title": "Zone Does Not Exist", "type": "https://api.weather.gov/problems/InvalidZone", "status": 404, "detail": "Forecast zone COZ238 does not exist", "instance": "https://api.weather.gov/requests/17515f95" }

What am I doing wrong here?

Only forecast zones have forecasts issued for them through the /forecast endpoint. If you want the fire weather forecast, get product FWF from the WFO for the point. To do this in your case, extract the WFO code from the forecastOffice field, then fetch https://api.weather.gov/products/types/FWF/locations/BOU where BOU is the WFO code, then get the @id for the product issuance you want (most recent is first).

Is that the data you were looking for?

If you're looking for fire weather element forecasts (haines index, etc.), there are some available through the /gridpoints endpoint. The link is available through the forecastGridData property on the /points endpoint.
