Weather in Funchal in May

Prime time. May is about as good as Funchal gets. Highs average 18.5 °C, lows 16.1 °C, and rain falls on 4 days — nothing in the month is working against you.

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

Rain falls on only 4 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; the day barely swings — 2.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 23.6 °C and the coldest night fell to 12.9 °C, and the wettest single day dropped 39 mm — roughly 195% of the month's rain in one day.

This is the volatile part. May rainfall has ranged from 3 mm to 98 mm across the twenty years measured — a 95 mm spread around an average of 20 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 sits around 17.7 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How May sits in the year

Temperatures hold steady either side: 17.1 °C in April, 18.5 here, 20.6 in June. Nothing about the timing within the month matters much.

Daylight in May

May is at or near the longest days of Funchal's year: 13.8 hours of daylight, gaining 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 19.5 °C in May — swimmable, but it takes a moment to commit. The sea peaks at 23.9 °C in September and bottoms out at 18.2 °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

Shoulder. The value months — prices ease off and you get the place closer to itself. May is the value pick for Funchal: it scores within 9 points of July without carrying July's prices.

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

May in Funchal versus nearby

If Funchal is one option among several, the nearby comparison is worth making. Las Palmas de Gran Canaria is a better bet in May — 2.4 °C warmer, 3 days less rain. Agadir is the weaker option in May — 12.8 °C warmer, 2 days less rain.

So: May works, with July the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
