What to Pack for Iceland in Autumn: A Practical Checklist

Start with a layering system, not a bigger suitcase

Autumn in Iceland means air temperatures roughly between 2°C and 10°C, with wind that makes them feel lower and rain that arrives sideways. The workable formula is a thin merino base layer, a fleece or light down midlayer, and a waterproof shell with taped seams and a hood that survives gusts. Buy or rent the shell before you fly if you can; Reykjavík outdoor shops around Laugavegur and Kringlan stock good options, but sizes thin out in late September. Skip cotton next to the skin entirely — it holds damp and chills you on a wet afternoon at Seljalandsfoss.

Two pairs of walking trousers and one warmer pair covers most trips. Add a compact down jacket for evenings; indoors, Icelandic buildings are well heated, so a midlayer you can strip off matters more than a heavy coat. Gloves, a buff and a warm hat are not optional from mid-September, especially on the Snæfellsnes peninsula or at Skógafoss, where spray soaks anyone standing close. Pack a dry bag or two — they cost little and protect cameras and spare socks in a daypack.

Footwear decides how much you enjoy the trip

Waterproof hiking boots with ankle support and a decent tread are the single best investment for an autumn trip. Paths around Þingvellir, the Reykjanes peninsula and the trail to Glymur get muddy and slick, and gravel car parks turn to slush. Bring boots you have already broken in, plus two pairs of wool socks and a spare insole. Trainers are fine for Reykjavík itself — the centre around Austurvöllur and Skólavörðustígur is compact and paved — but they will not serve you on the South Coast.

If you plan to hike or join a glacier walk near Skaftafell, check whether crampons or boots are supplied by the operator before you pack your own. Many guided tours include the hardware; hiring boots locally is possible but adds cost and fitting time. A pair of lightweight camp shoes or sandals is useful for guesthouse showers and hot tubs, which are common even at mid-range hotels. Pack a small boot brush or bag — keeping mud out of a hire car is expected, and cleaning fees are real.

Daypack contents, swimwear and the paperwork

Your daily bag should hold a 1-litre water bottle, snacks, a power bank, a headtorch and a light dry bag. Daylight shrinks fast: by early October Reykjavík gets roughly 11 hours of light, dropping to about 9 by month's end, so a headtorch earns its place if you are driving beyond the city or chasing the aurora. Bring a compact tripod if night photography matters to you. Sunglasses and sunscreen still matter on clear days, and a small thermos is a genuinely Icelandic habit worth copying.

Pack swimwear and a quick-dry towel without fail — geothermal pools at Laugarvatn Fontana, the Secret Lagoon at Flúðir and Reykjavík's own Sundhöllin are the best value hours of any autumn trip. Bring any prescription medicine in original packaging with a copy of the prescription, plus a printed or offline copy of your booking confirmations. Card payment is near-universal, but a little Icelandic cash is handy for rural honesty boxes. Leave the umbrella at home; it will not survive the wind.

Where to base yourself and what to leave behind

For a first autumn trip, base two or three nights in Reykjavík (101 or 105 postcodes put you walking distance from Hallgrímskirkja and the harbour) and then one or two nights along the South Coast near Vík or Hvolsvöllur. From Reykjavík, Þingvellir is about 50 minutes by car and Vík roughly 2.5 hours on Route 1. Akureyri, 4.5 to 5 hours north, suits a longer itinerary. September holds more daylight and marginally better odds of dry weather; October brings darker evenings and better aurora chances, at the cost of more wind and rain.

Skip formal evening wear, heavy jeans and anything you would mind getting wet. Jeans dry slowly and are miserable on a damp boat or beach. A single smart-casual outfit is enough for Reykjavík restaurants. Book accommodation early for the first week of October and around the Reykjavík Jazz Festival and Iceland Airwaves periods, when city rooms tighten. I would book a mid-range hotel in central Reykjavík with breakfast included and free cancellation, then add rural guesthouses later once the forecast firms up.
