September in Cádiz: the vendimia fortnight, and the coolest capital in Andalucía

Cádiz province splits down the middle in September, and the difference is bigger than the map suggests. Cádiz city averages 26.3°C by day and 20.3°C at night — barely six degrees between the two, because the Atlantic is on three sides of it. Jerez, twenty-five minutes inland, averages 30.4°C by day and 17.0°C at night.

Four degrees hotter in the afternoon and three cooler after dark. That is the difference between a bodega day and a beach day, and it is worth choosing deliberately.

What the weather actually does

September is still dry on both sides: 24mm in the city, 27mm in Jerez. The drop-off comes immediately after — Jerez goes from 27mm in September to 72mm in October, which makes September the last dependably dry month on the Costa de la Luz.

Atlantic sea temperature runs around 21.5–22°C, a degree or two cooler than the Mediterranean and noticeably choppier. Tarifa sits at about 22.4°C with the levante and poniente winds that make it what it is. The levante eases through the month.

What is on in September 2026

Fiestas de la Vendimia, Jerez — 29 August to 13 September. Sixteen days and more than a hundred activities. The institutional opening is the Ceremonia de la Pisa de la Uva on Tuesday 1 September, when the first grapes are trodden in public outside the cathedral.

The programme is published by the ayuntamiento and flagged as subject to change, so check before fixing a date around a specific event.

Village ferias through the province: Jimena de la Frontera 3–6, Prado del Rey 4–6, Bornos and Ubrique both 9–13, Villamartín 16–20, Trebujena 17–20 September.

Note what is not in September: Carnaval is February, and the province has no single great feria the way Jerez has the Feria del Caballo in May.

What life is like

The grapes are already in. Jerez picks palomino from early August, so by September the bodegas are fermenting rather than harvesting — the Vendimia is the celebration, not the work. What it does mean is that tabancos and bodegas run tastings and flamenco that do not exist the rest of the year.

On the coast, the beach bars at Zahara, Bolonia and Caños thin out sharply after the first weekend of the month, when the Spanish holidaymakers go home. The beaches themselves stay warm and get emptier by the week.

The one thing to do in September

A sherry bodega in Jerez during the vendimia fortnight. The tastings are better, the tabancos put on flamenco, and the pisa is public. Fino and manzanilla drunk within a few miles of where they were made taste different from the same bottle anywhere else, and this is the fortnight the town is most willing to show you why.
