Reykjavik Weather in April

April feels damp and chilly

April in Reykjavík is a cool, wet start to spring. Days reach about 5°C, while nights hover near 1°C. Rain falls often, and skies are usually cloudy, so the city can feel raw even with longer daylight.

You can still enjoy a walk around the Old Harbour, visit Hallgrímskirkja or warm up in a geothermal pool. But don't build your whole day around clear views or a long outdoor outing. Keep indoor stops like the National Museum of Iceland in your plans, too.

What's on in April

The main local event is Sumardagurinn fyrsti, Iceland's First Day of Summer. It falls on the first Thursday after April 18 and is marked with parades and family events, though the weather can feel far from summery.

If you hate crowds, April is a good bet compared with July, Reykjavík's peak summer month. The city is generally quieter, and stays often cost less than in high season. Easter can bring a busier spell, so the mood varies across the month.

Make the weather work for you

There's enough daylight for sightseeing, but sunshine is limited. Treat a bright spell as a bonus, not a promise. April works well for a city break built around cafés, museums and short walks between sights. It's less suited to a trip that depends on long, dry hikes.

Practical tip: use the city's public pools to take the edge off a damp day. Sundhöllin, near Hallgrímskirkja, has indoor and outdoor pools, so you can still enjoy a soak if the weather turns. Reykjavík's hot dogs are another easy warm-up between stops.
