Weather in Faro in September

Prime time. If you get to pick your dates, September is the one. Highs average 25.7 °C, lows 19.2 °C, and rain falls on 3 days — nothing in the month is working against you.

September ranks 3 of 12 in Faro. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 3 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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest September day reached 33.5 °C and the coldest night fell to 14.5 °C, and the wettest single day dropped 44 mm — roughly 191% of the month's rain in one day.

This is the volatile part. September rainfall has ranged from 0 mm to 87 mm across the twenty years measured — a 87 mm spread around an average of 23 mm. The average is real but almost no individual September looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 12.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How September sits in the year

The month is on the way down: 2.7 °C cooler than August, with October dropping another 2.9 °C. The first week and the last are not the same trip. Rain is the thing that moves: October brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in September

12.5 hours of daylight, losing 1.2 hours across the month. That is between Faro's extremes of 14.7 and 9.6 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 22.7 °C in September — comfortable for a proper swim. This is the warmest the water gets all year.

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.

September in Faro versus nearby

If Faro is one option among several, the nearby comparison is worth making. Évora is the weaker option in September — 4.5 °C warmer, 1 day more rain. Sevilla is the weaker option in September — 7.3 °C warmer, 1 day more rain.

So: September is effectively as good as it gets here — 4 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
