Iceland's Highlands Open in Late June
The interior highlands open in late June and close again in mid-September. About ten weeks. After that the F-roads are unpassable and Landmannalaugar is gone for the year.
Inside that window, river crossings are the variable. Conditions change overnight based on rainfall and snowmelt. A highland day decided the night before is a coin flip. A highland day decided in the morning based on actual overnight conditions is a different trip.
Highland time gets built into Iceland summer itineraries with day-of flexibility, not a fixed schedule.
