Drop-first decision
Guide / live check
What changed: the bay is exposed and the walk has stopped being pleasant.
Drop first: the extra stretch toward Sun Voyager or farther along the shore.
Keep: Harpa as the turning point, then return through the older streets where shelter is easier to find.
Check before leaving: the capital-area forecast and any current warnings.
Reykjavík plans usually go wrong by keeping too much, not by starting with too little. When wind, rain, a late check-in, or tired legs cut the usable day, protect one good main activity and remove the part that creates the most movement.
This is a drop-first list: seven common situations, the piece I would remove, and the part I would keep. Check the live weather, opening hours, and transport before leaving.
