September in Córdoba: the heat breaks in the last ten days, and the PX grapes go out in the sun

Córdoba is the hottest city in Spain in summer and it does not let go quickly. The September average of 31.6°C hides a steep slide: about 34°C on the 1st and 28°C by the 30th. The heat genuinely breaks, but not until the last ten days.

If you can pick your week, pick the last one. If you cannot, plan around the middle of the day rather than through it — the Mezquita at opening, a long indoor afternoon, and the city again from six.

What the weather actually does

Córdoba airport averages 31.6°C by day and 16.9°C at night in September, with 35mm of rain — the wettest September of the inland capitals, though that still amounts to very little. The chance of a wet day rises from 4% at the start of the month to 13% at the end.

Nights are the reward. At around 17°C average they are properly cool, which is not true in August, and the courtyards and riverside come back into use after dark.

What is on in September 2026

71ª Fiesta de la Vendimia Montilla-Moriles, Montilla — 3–7 September. Declared of Tourist Interest, and the province’s main September event. The DOP has confirmed the 2026 harvest is already under way and of good quality. Dates come from regional press rather than the ayuntamiento site, so treat them as reported rather than official.

Village ferias run through early September across the province, including Priego de Córdoba’s Feria Real, though 2026 dates are largely unpublished.

One thing to be clear about: the patios are closed in September. The Fiesta de los Patios is an early-May event, and a lot of visitors arrive expecting otherwise.

What life is like

The Pedro Ximénez harvest in the Sierra de Montilla is what the province is doing this month, and it produces one of the odder sights in Andalucía: grapes laid out on esparto mats in open fields to raisin in the sun. The asoleo is what concentrates the sugar that makes PX the near-black dessert wine it becomes.

It lasts a few weeks. There is no visitor infrastructure around it — you drive the roads south of Montilla and the fields are simply covered.

The one thing to do in September

The asoleo and the public treading at Montilla during the vendimia. Sun-drying grapes on mats is a September-only landscape, and the festival is the one week the bodegas open up around it. Montilla is forty-five minutes south of Córdoba city.
