December in Cádiz trades Northern European frost for a 16.9 °C Atlantic afternoon, 166 hours of winter sunshine, and six weeks of Christmas lights across the historic peninsula. Nights are lively with festive flamenco (Navidad Flamenca), while daytime sightseeing requires careful planning around Spain's early-December Constitution holidays and the closures on 24, 25, and 31 December.
For the broader low-season picture through February, read Cádiz in winter. For full 12-month climate comparisons, see Cádiz weather by month.
According to AEMET 1991–2020 climate normals for Cádiz (station 5973), December records a monthly mean temperature of 13.9 °C, an average daytime maximum of 16.9 °C, and an average overnight minimum of 10.9 °C. Snow days are 0.0, and clear skies average 7.9 days across the month with 166 hours of sunshine.
December averages 92 mm of rainfall spread across 8.1 rain days (days with at least 1 mm of precipitation) and 76% relative humidity, with 1.4 thunderstorm days. By comparison, January cools slightly to a 16.0 °C daytime high and 9.4 °C overnight low, but dries out to 69 mm of rain across 6.9 days and 184 sunshine hours.
| Month | Mean (°C) | Avg High (°C) | Avg Low (°C) | Rain (mm) | Rain Days (≥1 mm) | Sunshine (hrs) |
|---|---|---|---|---|---|---|
| December | 13.9 | 16.9 | 10.9 | 92 | 8.1 | 166 |
| January | 12.7 | 16.0 | 9.4 | 69 | 6.9 | 184 |
Cádiz's extraordinary Christmas lighting runs continuously from 30 November to 6 January, illuminated every evening from 18:00 until midnight (00:00). Because sunset falls early in December, the lights transform the narrow limestone streets of the Casco Antiguo just as the evening paseo and tapas hours begin.
The civic anchor of the display is Plaza de San Juan de Dios, framed by the Neoclassical Ayuntamiento (Municipio), the Church of San Juan de Dios, and the Casa de los Pazos Miranda. For nativity scenes (belenes) and festive street traditions across the city, read our Christmas in Cádiz page.
Early December brings two headline evenings to the Gran Teatro Falla on Plaza Fragela:
“At six in the evening the Christmas arches light up across Plaza de San Juan de Dios, and the sound of December in Cádiz is flamenco villancicos drifting out of the tabernas.”
Spain's December calendar has two major holiday clusters: the early-December Constitution and Immaculate Conception bridge (Puente de Diciembre, 6 to 8 December) and the Christmas to Three Kings period (24 December to 6 January). Andalucía's official 2026 public holiday calendar designates Friday 25 December as the Natividad del Señor public holiday, followed by 1 January and Wednesday 6 January (Epifanía del Señor).
Monument opening rules split sharply between municipal sites, regional Junta de Andalucía museums, and private towers:
| Monument / Museum | 6 & 8 Dec | 24 & 31 Dec | 25 Dec | 1 & 6 Jan |
|---|---|---|---|---|
| Torre Tavira | Open 10:00–18:00 | Open 10:00–18:00 | Closed | Closed |
| Casa de Iberoamérica | Check local schedule | Open 10:00–14:00 (23 Dec–6 Jan) | 10:00–14:00 Christmas schedule | 10:00–14:00 (to 6 Jan) |
| Museo de las Cortes | Open 09:30–14:00 | Check municipal notice | Closed | Closed |
| Museo de Cádiz | Holiday morning hours | Closed | Closed | Closed |
| Roman Theatre | Closed (6, 7 & 8 Dec) | Closed | Closed | Closed |
Christmas Day (25 December) walking strategy
Because Torre Tavira, the Museo de Cádiz, and the Roman Theatre all close on 25 December, treat Christmas Day as an outdoor coastal day: walk the Cádiz seafront walk around Campo del Sur to La Caleta, stroll through Parque Genovés, and return at 18:00 for the Christmas lights.
In December, staying inside the pedestrianised Casco Antiguo puts you within a ten-minute walk of the Christmas lights, the Mercado Central de Abastos, and the sherry bars of La Viña. For a traditional winter base, Hotel Argantonio lights the fireplace in its main lounge throughout the winter months, turning the ground-floor salon into a warm gathering spot after an evening walk. For contemporary sea views over the Atlantic, Parador de Cádiz sits next to Parque Genovés and La Caleta.
Local correspondent tips
Junta de Andalucía sites (Museo de Cádiz and the Roman Theatre) shut all day on both Christmas Eve (24 December) and New Year’s Eve (31 December). Keep your sightseeing moving by booking Torre Tavira (open 10:00 to 18:00) or visiting Casa de Iberoamérica on its special 10:00 to 14:00 Christmas schedule.
Cádiz illuminates its festive arches daily from 18:00 to midnight between 30 November and 6 January. Start at Plaza de San Juan de Dios outside the Ayuntamiento at 18:00 sharp, then follow the lit shopping streets toward Plaza de las Flores before the tapas bars fill up.
December relative humidity averages 76% with overnight lows of 10.9 °C, which makes Atlantic evenings feel cooler than the thermometer suggests. Hotel Argantonio in the historic centre lights the fireplace in its main lounge throughout the winter months.
Cádiz stays mild in December because the peninsula is surrounded by the Atlantic Ocean. AEMET 1991–2020 climate normals show an average daytime high of 16.9 °C, an average overnight low of 10.9 °C, a monthly mean of 13.9 °C, 166 hours of sunshine, and 0.0 snow days.
Cádiz's extraordinary Christmas lighting runs from 30 November through 6 January and is switched on every evening from 18:00 until midnight, with Plaza de San Juan de Dios as the main civic focal point.
On Christmas Day (25 December, Natividad del Señor), Torre Tavira, the Museo de Cádiz, and the Roman Theatre are all closed. On 24 and 31 December, the Museo de Cádiz and Roman Theatre close, whereas Torre Tavira stays open (10:00–18:00) and Casa de Iberoamérica opens on its Christmas schedule from 10:00 to 14:00.
The Roman Theatre closes across 6, 7, and 8 December. By contrast, the municipal Museo de las Cortes de Cádiz opens special holiday morning hours from 09:30 to 14:00 on both 6 and 8 December, and Torre Tavira operates as normal from 10:00 to 18:00.
Yes. December is the season for festive flamenco villancicos and Navidad Flamenca. On 1 December 2026 at 20:00, the Gran Teatro Falla stages "Puro Cádiz: Bienvenidos a la nueva experiencia de la Navidad Flamenca" with singers May Fernández, Anabel Rivera, and Reyes Martín.
Both 1 January (Año Nuevo) and Wednesday 6 January 2026 (Epifanía del Señor / Three Kings' Day) are official public holidays in Andalucía. Torre Tavira, the Museo de Cádiz, and the Roman Theatre are closed on both dates, while Casa de Iberoamérica includes 23 December to 6 January in its 10:00–14:00 Christmas window.
