Weather in Gasteiz / Vitoria in May

A good month. May works. It is not the peak, but nothing about it fights you. Highs average 18 °C, lows 8.9 °C, and rain falls on 13 days — nothing in the month is working against you.

May ranks 6 of 12 in Gasteiz / Vitoria: 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. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average May reaches 30 °C. Across the twenty years measured, the hottest May day reached 31.6 °C and the coldest night fell to 1.6 °C, and the wettest single day dropped 46 mm — roughly 63% of the month's rain in one day.

May is moderately variable: 27 mm in the driest year against 155 mm in the wettest, around an average of 73 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way up: 2.9 °C warmer than April, and June adds another 4.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in May

14.6 hours of daylight, gaining 1 hours across the month. That is between Gasteiz / Vitoria's extremes of 15.3 and 9.1 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 22.7 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

May in Gasteiz / Vitoria versus nearby
