Weather in Vigo in March

Shoulder season. March sits in between. You will get good days and you will lose some. Highs average 15.5 °C, lows 8.1 °C, and rain falls on 13 days — nothing in the month is working against you.

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

This is wet-season rain: 13 wet days and 5 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Pack for 15.5 °C days and 8.1 °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 26.5 °C and the coldest night fell to -1.9 °C, and the wettest single day dropped 52 mm — roughly 41% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 21 mm to 448 mm across the twenty years measured — a 427 mm spread around an average of 127 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 5.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How March sits in the year

The month is on the way up: 1.9 °C warmer than February, and April adds another 1.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.9 hours of daylight, gaining 1.4 hours across the month. That is between Vigo's extremes of 15.2 and 9.1 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 13.8 °C in March — too cold to swim without a wetsuit. The sea peaks at 18.5 °C in August and bottoms out at 13.7 °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 Vigo versus nearby

If Vigo is one option among several, the nearby comparison is worth making. Braga is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Aveiro is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: March is a compromise. July is 33 points better and is what Vigo is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
