The present invention belongs to the field of automobiles, and provides a method for scheduling a travel time according to a weather forecast, and a GPS navigation. The method comprises: recording a navigation weather detection end; monitoring a navigation path of a user; when the user uses an on-board navigation planning path, detecting path weather at the navigation weather detection end; when extreme weather is present on the path, planning a travel time according to a path algorithm. In the present invention, the navigation weather detection end is recorded, and the path algorithm can help the user avoid a road section when the user is using the on-board navigation planning path and extreme weather is present on the path, thereby ensuring that the user travels safely.
