Post-season — prices falling after the travel period, beaches and attractions quieter.
September is the coldest winter month in Iceland — with highs of only 10°C, it holds little appeal for sun-seekers. Better travel in June, July, and August.
Temperatures reach a maximum of 10°C during the day and drop to 6°C at night — warm layers recommended. With 5 sunshine hours per day and 14 rain days (124 mm), this is one of the cloudier months. At 10°C, the water is still quite cool in September — a wetsuit may be useful.
Pack warm clothing and sturdy footwear. Cool temperatures make hiking and cultural trips enjoyable — beaches are off the agenda.
