The sea is not the reason to come. Sightseeing and walking the city are.

When can you swim in Reykjavik?
The sea near Reykjavik never reaches 68°F (20°C). June averages 49°F (9°C) and September 50°F (10°C).
The coldest water comes in January through March, at 41°F to 42°F (5°C to 6°C). These are monthly averages, so a given day can run a little either way. The start of summer, in May at 45°F (7°C), is still cold.
When is Reykjavik cheapest and least crowded?
The calendar sets the busy stretch. From July 17 through the end of August, the city runs a festival almost every week, from the street food festival to Pride and Culture Night. Culture Night is a city center festival that draws a wide range of people, and many families and groups of friends meet up for it by tradition.
The landmarks are busy too. Hallgrímskirkja is one of the most visited places in Iceland, and the tower is among the most visited spots in Reykjavik. Harpa has drawn millions of guests since it opened in May 2011.
The trade-off is daylight.
January is hard for anyone planning long days outdoors.
