Morning: museums and coffee
Start at the National Museum on Sudurgata (2,500 ISK, opens 10am). Give it 90 minutes — the Settlement to Present exhibition is one long, well-lit corridor and genuinely good. Walk five minutes to Cafe Loki opposite Hallgrimskirkja for rye bread with pickled herring and a shot of Brennivin at 12:30. If you want more culture, the Settlement Exhibition on Adalstraeti is built around an actual Viking longhouse foundation — 45 minutes, 2,200 ISK.
Alternative if museums bore you: the Perlan (Wonders of Iceland) has an ice cave you can walk through and a planetarium showing an aurora film. 6,490 ISK, but it kills a full three hours.
Afternoon: hot water fixes everything
Head to the Sky Lagoon in Kopavogur (bus 35 from the centre, or 15-minute drive). The seven-step ritual — hot pool, cold plunge, sauna, mist, scrub, steam, shower — is designed for exactly this weather. Two hours, 12,990 ISK. Or the neighbourhood pools: Laugardalslaug or Vesturbaejarlaug, both under 1,500 ISK, are where locals actually go in the rain. Dinner at Matur og Drykkur or Grillmarkadurinn back in 101. Sleep central Reykjavik so you can walk home in the wet.

Is the Blue Lagoon better than Sky Lagoon in the rain?
Sky Lagoon is closer (10 minutes from central Reykjavik vs 45 to the Blue Lagoon) and cheaper. Blue Lagoon wins on scenery, but you cannot see the scenery in the rain.
What if it is stormy, not just rainy?
Check safetravel.is. Orange or red weather alerts mean stay indoors — the wind here rips car doors off. Museums, pools, and the movie theatres on Laugavegur are your day.
