Weather in Gijón in March

Shoulder season. March sits in between. You will get good days and you will lose some. Highs average 15.8 °C, lows 8.6 °C, and rain falls on 13 days — nothing in the month is working against you.

March ranks 8 of 12 in Gijón: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 13 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.8 °C days and 8.6 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest March day reached 26.2 °C and the coldest night fell to 0 °C, and the wettest single day dropped 31 mm — roughly 38% of the month's rain in one day.

March is moderately variable: 19 mm in the driest year against 169 mm in the wettest, around an average of 82 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 12.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How March sits in the year

Temperatures hold steady either side: 13.6 °C in February, 15.8 here, 17.3 in April. Nothing about the timing within the month matters much.

Daylight in March

11.8 hours of daylight, gaining 1.5 hours across the month. That is between Gijón's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 12.5 °C in March — too cold to swim without a wetsuit. The sea peaks at 20.9 °C in August and bottoms out at 12.5 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Gijón versus nearby

If Gijón is one option among several, the nearby comparison is worth making. Valladolid is close enough to be a coin toss — within a degree on temperature, 4 days less rain. Bilbao is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: March is a compromise. July is 23 points better and is what Gijón is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
