Combined Summary Requests

This endpoint provides a single resource for being able to route, geocode, and forecast all with one request. Functionally, it serves as a combination of the Directions, Reverse Geocode, and Forecast Summary endpoints. Those endpoints are provided as composable pieces for you to exercise more granular control, but if you prefer to simplify your API usage by making a single request, this endpoint achieves the same effect.
This endpoint does not support alternative routes. If you wish to generate forecasts for a set of alternate routes, please refer to the individual endpoint resources.
Examine the available geocode endpoints for more details about address-like representations or GPS coordinate representations for use as input in query parameters.
The results of this request will be similar to the usual Forecast Summary response, but with the routing polyline also provided with the response, as well as optionally returning geocode information.
Use of this endpoint may be more limiting for long-running requests than the separate, individual resources. In particular, you may be more likely to experience timeouts for an excessively long-running request. If you experience this, you may have better luck with the individual resources.
That said, it is also quite likely that this endpoint will be more performant than using the individual resources, due to less time spent in the roundtrip between our servers and your systems.

Query Parameters


A series of locations that represent the desired trajectory of travel. These can be address-like representations or (lat,lng) GPS coordinates. Each specified point should generally be considered a milestone/waypoint in the trajectory, but can also be treated as intermediate waypoints used to guide the results to follow a particular route. For best results, URL-encode this parameter.
(required; at least 2)


Expected average speed, in meters/hour. Selected forecast points will use this setting to estimate useful points for retrieving weather results. The forecast points may not precisely match this setting.
This parameter cannot be used if the num_forecast_points parameter is also set.
(optional; default=97000 meters/hour, or approximately 60 miles/hour)


The exact number of forecast points to return. These will be evenly distributed across the route.
This parameter cannot be used if the speed parameter is also set.
(optional; default=indeterminate)


Desired mode of transit.
Available transit modes:
  • car - Default routing and weather responses
  • truck - Routing avoids small roads; weather results are sensitive to high winds
  • motorcycle - No impact on routing; weather results are sensitive to precipitation
  • bicycle - No impact on routing; weather results are sensitive to precipitation
(optional; default=car)


The preferred units of the response.
Available units:
  • imperial - Imperial units (Fahrenheit and/or miles)
  • metric - Metric units (Celsius and/or kilometers)
(optional; default=imperial)


The maximum number of days for which to aggregate the summary across (starting today).
(optional; default=all)


The date at which to start aggregating the summary, in YYYY-mm-dd format. This parameter is used when you want to start aggregating the summary starting at a future date (for example, getting the summary starting 3 days from today).
Use of this parameter also requires use of the tz_offset parameter.
(optional; default=today)


The time zone offset from GMT for the requested date, offset in hours. Decimal values are allowed for time zone offsets that are not whole numbers.
Use of this parameter also requires use of the start_date parameter.
(optional; default=0)


A boolean value for whether to generate descriptive geocode information with the returned points. This is often used to provide more human-friendly descriptions of the locations.
(optional; default=false)


The cost of this request will vary, depending upon the number of forecast locations generated, as well as whether geocoding information is returned.

Wind prone areas could see gusts up to 50 mph Monday night. * Humidity...10-15% along and east of US-395. 15-20% west of US- 395. RH will increase Monday night to near 40%. * Duration...3 to 7 hours of critical conditions Monday afternoon. Gusty winds will last for over 18 hours. * Impacts...The combination of gusty winds and low humidity can cause fire to rapidly grow in size and intensity before first responders can contain them.",
