Weather in Faro in May

Prime time. If you get to pick your dates, May is the one. Highs average 22.1 °C, lows 15.2 °C, and rain falls on 5 days — nothing in the month is working against you.

May ranks 5 of 12 in Faro: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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 32.9 °C and the coldest night fell to 10.1 °C, and the wettest single day dropped 46 mm — roughly 131% of the month's rain in one day.

This is the volatile part. May rainfall has ranged from 0 mm to 195 mm across the twenty years measured — a 195 mm spread around an average of 35 mm. The average is real but almost no individual May looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 14.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How May sits in the year

The month is on the way up: 3.1 °C warmer than April, and June adds another 3.5 °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

May is at or near the longest days of Faro's year: 14.1 hours of daylight, gaining 0.8 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 18.6 °C in May — swimmable, but it takes a moment to commit. The sea peaks at 22.7 °C in September and bottoms out at 16.5 °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

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 Faro versus nearby

If Faro is one option among several, the nearby comparison is worth making. Évora is close enough to be a coin toss — 3.2 °C warmer, 1 day more rain. Sevilla is close enough to be a coin toss — 6.4 °C warmer, the same number of rain days.

So: May works, with June the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
