Return ranked weather conditions, an icon, and a plain-language summary for each requested hourly interval, local calendar day, and day or night period across a point forecast's full 360-hour horizon.
This endpoint is available only for wm-6 .
| Name | Description | Format |
|---|---|---|
| coordinates Required |
A semicolon-separated list of latitude,longitude tuples. One
forecast object is returned for each coordinate, preserving the
input order. Longitude uses the -180 to 180 convention. | lat,lon;lat,lon;... |
| hourly_interval Optional | Duration, in hours, of each condition block in the hourly forecast. Defaults to 1. | 1, 2, 3, 4, 6, or 8 |

| coordinates Required | string or array |
Coordinates supplied as a semicolon-separated string or a list
of latitude,longitude tuples. Results preserve the input order. Longitude uses the -180 to 180 convention. |
| model Required | string | Set to wm-6 . |
| hourly_interval Optional | integer | Duration, in hours, of each condition block in the hourly forecast. Defaults to 1. |
All response arrays are chronological. Each window includes its start_time and excludes its end_time , so adjacent windows do not overlap. Although local time determines the daily and day/night boundaries, every timestamp is returned in UTC. The hourly array covers the fixed 360-hour horizon beginning at forecast_zero in its entirety.
| Block | Behavior |
|---|---|
| hourly | Contiguous windows anchored at forecast_zero , each containing the number of hours selected by hourly_interval . The interval is measured in hours and defaults to 1 hour; changing it partitions the same 360-hour horizon into larger blocks. |
| daily | Local midnight-to-midnight windows. The first and last windows are clipped to the forecast horizon. Daylight-saving transitions can produce 23- or 25-hour windows. |
| day_night | Alternating local sunrise-to-sunset day windows and sunset-to-sunrise night windows. The first and last windows are clipped to the forecast horizon. If an astronomical sunrise or sunset is unavailable for a polar location, the endpoint falls back to 06:00 and 18:00 local time. |
