Cádiz in October: weather, the sea and what is open

The sea and beach days

Searches for this month often ask for a sea temperature. There is no official October figure to quote: AEMET's normals cover the air, not the water. What can be said is that the Atlantic holds less warmth than the air above it, and a swim is a short, brisk one. The current reading for the day is on AEMET's beach forecast for Cádiz.

Beach days still work, mostly as sun and sand rather than long swims. La Caleta sits in the old town, and Playa Victoria runs for 2,800 metres along the seafront promenade. The council uses a three-flag system: red means no bathing, yellow means caution, and green means good conditions. Obey the flag over the thermometer.

Two rules from the council's beach pages matter on an autumn walk. Pets are not allowed on any of the municipal beaches, so a dog cannot join you on the sand. And if a current pulls you out to sea, the council's advice is not to swim against it. Swim parallel to the shore instead. In an emergency, alert the lifeguards, the municipal police on 091, or 112.

Which beach suits which day, and how the wind changes the choice, is covered in our guide to the beaches of Cádiz.

What is open

The big change on 1 October is the timetable, not the list. The sights below are open, on winter hours.

Torre Tavira

Torre Tavira lists 10:00 to 18:00 from October to April, and last admission is one hour before closing. Visits are by prior booking made on the tower's own site, and the tower says advance booking is essential, so reserve before you arrive.

The Roman theatre

The Roman theatre moves to its winter timetable on 1 October: Monday to Saturday from 10:00 to 16:30 and Sunday from 10:00 to 14:00. It is closed on the first Monday of every month, and on 1 and 2 November. The Junta de Andalucía also states that access to the excavation itself is temporarily restricted while extension works continue, so the interpretation centre is the part to plan around. Contact the site before you visit.

Castle of San Sebastián

The Castle of San Sebastián is listed by the council as open every day from 9:00 until sunset, with free entry. Sunset comes earlier through October, and the council notes the hours can change with the weather, so go in the morning or early afternoon and look at the sky first. The seafront walk that leads there is free whatever the opening hours.

Restaurants, bars and shops keep no single published timetable. Check the venue's own page or ask at the tourist office, particularly on 1 November, a public holiday when the Roman theatre is closed.

A wet-day plan

With about 5.6 rain days in the month, expect one or two disrupted days on a week-long trip. Keep one fixed point per day and let the rest move.

1. Book the Torre Tavira slot for a clear morning, since the camera obscura needs sun.
2. Keep the Roman theatre centre and the museums for the wet afternoon.
3. Use the two-day itinerary as a base and swap its outdoor stops for indoor ones.
4. If the whole day is lost, a train or boat to the bay towns is a better use of it. The day trips guide compares them.

Cruise passengers calling in October have a separate walking plan in the cruise port day guide.

Events in October

No October 2026 event with an official date was available from the council's tourism pages when this guide was written, so none is listed here. Look at the Ayuntamiento's cultural programme before you book, and treat any date you find elsewhere as unconfirmed until it appears there.

The city's headline festival is a few months away. Carnival is covered in the Cádiz Carnival guide, which is the page to read if you are choosing between October and February.
