Seasons in Iceland
Storm season runs October to April
Iceland is in its storm season right now, October to April. Most trips are unaffected, but a storm reroutes flights and closes beaches at a day's notice — the packing consequence is a buffer day and a charged power bank, not different clothes.
Going in September
The open season: long days, passable roads and the mildest weather of the year. Still windy, still wet, still worth a proper shell.
What this means for your bag
Something genuinely windproof
Wind is what makes the cold unbearable here, and an umbrella is useless in it. A hood that closes, and gloves.

Not a winter coat — it stays warm through the rain. A light hooded shell that folds into its own pocket ends up in the day bag instead of the hotel room.

Three thin layers beat one heavy one: they cover a wider range and pack smaller. A base layer, a fleece and a shell.
