Weather in Iceland in March

Facts verified 2026-08-04Updated 2026-08-04Weather

Winter or spring? Both, on one table: records from 18.1°C to −16.4°C, the equinox landing mid-month, and the year’s fastest light gain.

Short answer

March temperature in Iceland: winter by the thermometer — normals of −1.3 to 4.2°C, records from 18.1°C to −16.4°C — and spring by the sky: the equinox lands on the computed table below, the day gains over three hours, and sunshine nearly doubles February’s. Live reading below.

What is the weather in Iceland right now?

The live weather feed is not answering right now, so no reading is shown rather than a stale one — the live board at Iceland Pulse carries the current picture.

March in Reykjavík — the whole table

MetricValueWhat it means
Mean daily high4.2°CWinter, still — on paper
Mean daily low−1.3°CNights keep freezing

Record low−16.4°CWinter’s teeth, still sharp

The record rows carry the month’s argument: 18.1°C and −16.4°C in the same column, thirty-four and a half degrees apart. March can hand out either inside one week, which is why the layered winter kit stays non-negotiable even as the sun climbs. The twelve-month context: the weather-by-month table.

How much daylight does March have?

The 20th is the equinox — and it reads more than twelve hours because daylight is measured to the sun’s refracted upper limb. The month gains 3 h 16 m — six to seven new minutes every day, the fastest of the year.

Is March winter or spring in Iceland?

Both — and now you have the numbers for each half. Winter: freezing nightly normals, a −16.4°C record, full snow and storm season, winter driving rules unbroken. Spring: the equinox on the table, the year’s fastest light gain, sunshine doubling, and the aurora season’s last full month running on those still-dark nights. Even the ice answers both ways — cave season holds early in the month and retires cave by cave as the thaw builds.

For everything beyond the weather — Beer Day, the equinox Peace Tower week — the March pillar carries the month; April is where the tug-of-war finally tips.

March weather — questions people actually ask

What is the temperature in Iceland in March?
Normals of −1.3°C to 4.2°C in Reykjavík — still winter, plainly — with the records sketching the month's split personality: 18.1°C at one end, −16.4°C at the other, nearly thirty-five degrees apart. March serves borrowed-spring afternoons and hard-winter snaps in the same fortnight. The dependable trend is light, not warmth: sunshine nearly doubles February's total and the day grows over three hours.
What is the weather like in Iceland in March?
The year's great tug-of-war: 80.7 mm of precipitation over 14 days arriving as snow, sleet and rain in rotation, storms still fully in season, roads still winter roads — while 110.3 hours of sunshine (nearly double February's) pour through the lengthening days. Locals treat March as winter with better lighting; visitors who pack accordingly get winter's scenery at increasingly humane hours.
Is March winter or spring in Iceland?
The honest answer is on this page's two tables: winter by temperature, spring by light. The normals and records stay wintry — nights freeze, −16.4°C has happened — but the equinox lands mid-month and the daylight gain runs at the year's maximum, six to seven minutes every day. Iceland's own tradition agrees: the old calendar waits until late April to declare summer. Pack for winter; plan for light.
What is the average temperature in Iceland in March?
A daily mean around 1.5°C in Reykjavík — the midpoint of the 4.2°C normal high and −1.3°C normal low — with the north and the interior running colder. As with every Icelandic month, the average hides the spread: single March days scatter from the mid-teens to deep frost, and the freeze-thaw cycle around zero is what glazes pavements and roads. Read the range; the mean is only its middle.
Does it still snow in Iceland in March?
Yes — March remains a full snow month, especially in the north and the mountains, and some of the season's biggest single dumps arrive late. The lowland difference is that cover cycles faster: the strengthening sun clears streets in days rather than weeks. Winter tyres remain standard and mandatory-condition driving persists all month; the live road state stays the first check of every morning.
What should I wear in Iceland in March?
Full winter kit with one addition: proper sunglasses. The low sun over snowfields is genuinely hard on the eyes just as its hours double. Otherwise the system is unchanged — insulated waterproof shell, warm mid-layer, thermals, hat, gloves, grippy waterproof boots, and the swimsuit that justifies itself in every month. Layers matter more than ever in the month of the 34.5-degree record spread.
Is March good for northern lights in Iceland?
The season's last full month, and a strong one: nights remain aurora-dark throughout (the equinox weeks even carry a statistical bump in geomagnetic activity), while March's brightening weather brings more clear spells than midwinter managed. By late month the evening window starts late and shortens fast — the season closes during April. If the lights are the mission, the first half of March is the safer bet.
