April is Iceland changing its mind. Snow retreats uphill, waterfalls swell with melt, the first puffins splash down on the cliffs, lambs arrive by the hundred thousand, and Icelanders celebrate the First Day of Summer while it is frequently still snowing, which tells you everything about the national temperament. It is shoulder season at its purest: low prices, thin crowds, and a country waking up.
The April Equation
Daylight rockets from 13.5 to 16.5 hours, ending the aurora season in its final week or two. Temperatures climb to 34 to 45°F (1 to 7°C). Lowland roads clear and stabilize; the highlands stay firmly shut. April is the cheapest pleasant month on the Icelandic calendar.
The Best Things to Do in Iceland in April
1. Waterfalls at Full Throat
Snowmelt makes April and May the loudest waterfall season of the year. Gullfoss, Skógafoss, Seljalandsfoss, and Dettifoss all run at maximum volume, and the path behind Seljalandsfoss usually reopens from its winter ice closure. Bring the waterproof layer; the spray is part of the show.
2. The Last Northern Lights
Early April still delivers aurora on dark clear nights, the elegant ending of the season before the midnight sun takes over. Treat any sighting as a parting gift and prioritize the first half of the month.
3. Puffins Return
The Atlantic puffin fleet returns to Icelandic cliffs through April: first arrivals at the Westman Islands, Dyrhólaey, and Borgarfjörður eystri. By month’s end the colonies are filling, weeks before the main tourist wave knows it.
4. Lambing Season
Roughly 400,000 lambs arrive each spring, mostly in late April and May, and rural Iceland reorganizes around them. Several farm stays welcome guests during lambing; for animal inclined travelers it is the most heart melting booking of the year.
5. The Full Ring Road Reopens (Sensibly)
April is the first month the complete circuit becomes a relaxed proposition: long days, clearing roads, winter scenery on the mountains and spring in the valleys. Ten days remains the comfortable number; a 4WD remains the smart rental.
6. Whales Ramp Up
April marks the real start of whale season in the north: humpbacks gathering in Eyjafjörður and Skjálfandi, with Húsavík’s boats returning to daily schedules. Reykjavík sailings continue year round.
7. Ski in the Morning, Beach in the Afternoon
April is Iceland’s spring skiing month: Hlíðarfjall often runs deep into the month and the Troll Peninsula heli season peaks, with corn snow descents that end near sea level. The same day can finish with a black sand beach walk in single layer weather.
8. The First Day of Summer (Sumardagurinn Fyrsti)
The first Thursday after April 18 is a public holiday celebrating summer’s official arrival, rooted in the Old Norse calendar that recognized only two seasons. Parades happen, ice cream is eaten outdoors regardless of temperature, and if the night before brings frost, tradition declares summer and winter “frozen together,” an omen of a good year. Join the optimism.
April Practicalities
Pack for two seasons in one suitcase: waterproof shell, warm mid layers, and sunglasses for 16 hour days. Easter week (when it falls in April) books accommodation and ski areas solid, with most businesses closed Maundy Thursday through Easter Monday; plan around it. Aurora hunters should front load the trip; puffin and whale fans should back load it.
