Weather in Recife in September

A good month. September works. It is not the peak, but nothing about it fights you. Highs average 28.3 °C, lows 22.9 °C, and rain falls on 13 days — nothing in the month is working against you.

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

Rain on 13 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 28.3 °C days and 22.9 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 31.5 °C and the coldest night fell to 20.9 °C, and the wettest single day dropped 72 mm — roughly 124% of the month's rain in one day.

September is moderately variable: 12 mm in the driest year against 120 mm in the wettest, around an average of 58 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 14.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How September sits in the year

Temperatures hold steady either side: 27.3 °C in August, 28.3 here, 29.8 in October. Nothing about the timing within the month matters much. Rain has already shifted: 9 days fewer than August had.

Daylight in September

Recife sits close enough to the equator that daylight barely moves all year — 12 hours in September, against a range of just 0.9 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 26.4 °C in September — warm enough to stay in as long as you like. The sea peaks at 28.8 °C in April and bottoms out at 26.4 °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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, August is the trade worth considering — 10 points weaker on weather, and materially quieter.

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

September in Recife versus nearby

If Recife is one option among several, the nearby comparison is worth making. Maceió is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Fortaleza is a better bet in September — within a degree on temperature, 12 days less rain.

So: September is effectively as good as it gets here — 1 points behind October, which is inside the margin where the weather stops being the deciding factor and price starts being it.
