Weather
Get a weather forecast along a route, where for each waypoint the correct forecast offset is chosen based on the estimated arrival time at that point. You provide a series of coordinates (the route) and a speed; the API calculates when you'll arrive at each point and returns the weather values for the requested elements at the matching forecast offsets. This gives you a time-dependent forecast per location instead of a static forecast for a single moment, which is useful for route planning, navigation, and logistics where weather conditions change along the way.
Available for all weather models except ensemble models.
