If you’re in the US, your tax dollars already pay for a weather API! The National Weather Service has an API that you can ping for forecasts of a specific latitude/longitude or forecast office/state/zip code (if you convert them to a latitude/longitude). One of the outputs will be a forecast of percent chance of precipitation as well as the forecasted amount (QPF = quantitative precipitation forecast). Here’s an FAQ webpage: NWS API . Otherwise, something like WeatherBELL may have what you’re looking for? More on reddit.com

Looking at the api documentation found HERE and HERE, you are calling the /gridpoints/{wfo}/{x},{y}/forecast/hourly call which will return the hourly weather forecast for the specified weather office {wfo} at the specified x-y coordinates. You can find a list of the weather offices HERE. Finding the X-Y coordinates for the weather offices may be a bit more tedious to find on the web.
If you happen have access to the GPS coordinates that you are working with you can use the /points/{x},{y} API call to get the information on the closest weather office to then pass to the /gridpoints/{wfo}/{x},{y}/forecast/hourly API call.
The flow of your application can look something like this:
Step 1: Get your map Geo coordinates. In my case, I am at 35,-106
Step 2: Make a call to the weather.gov API: https://api.weather.gov/points/35,-106. You will be presented with some JSON data. Look for the cwa key in the properties object. That will be the forecast office to pass into the next api call. In my case, the key is ABQ. You also need to find the gridX and gridY keys in the properties. These are the XY coordinates that you will use for the {X},{Y} parameters in the API call. In my case X = 121 and Y = 112.
Step 3: Make the final call to the weather.gov API: https://api.weather.gov/gridpoints/ABQ/121,112/forecast/hourly

As long as you have the latitude/longitude of the location you want the forecast for, then:
- Get the point metadata from https://api.weather.gov/points/{lat},{lon}
- Follow the link in the
forecastHourlyproperty to get the forecast
This is preferable to constructing the URL as in the other answer, as your program won't break if the URL scheme changes in the future.

If you call /points/XXXXXX,YYYYYYY, with the lat/lon, the properties/observationStations key provides another API call, /gridpoints/AA,BB/stations, that returns a list of weather stations near that point, sorted by distance. You can take a station from that list, call /stations/STATIONID/observations, and that gives you the weather at that station.

r/weather on Reddit: Weather API service
December 21, 2023 -
Hello all!
I have a client (think roofing) that wants to be able to schedule roofing crews around upcoming weather forecast. Can someone recommend a service (reasonably priced is ok) that can give us the forecast as a percent chance of rain by zip code that we can refresh every hour or so to put into the scheduling algorithm? We are thinking setting up a program that runs every hour and updates a weather table with the regions zip codes and a column for each upcoming day that we put the percentage chance of rain.
Thanks!

As pointed out, you can use the NWS API for free in the US. I will say it’s not without its issues. I have an app that relies heavily on the NWS API and it has been the biggest point of failure at any given time. The reliability lately has gotten a lot better, but I still will get 404 and 503 errors, or sometimes even just straight up outdated forecasts (like days old). I have coded against the Aeris Weather API and it’s featured, but expensive. You could check out the Azure Maps API that uses AccuWeather as its data source for weather and they give relatively generous free calls. Beyond the free tier, the pricing is very reasonable. You can also use the Azure geolocation API to convert your job addresses to lat/long and store that in your database, most weather APIs prefer to work in coordinates. At that point you can easily leverage geospatial functions of the database to group job areas regionally how you see fit, not just ZIP (though nothing precludes you from doing that).
