Monthly weather and packing notes
December suits a warm coat, scarf and gloves. Keep an indoor alternative and check festive closures before committing to an outdoor-to-museum plan. In Swansea, plan one outfit for the Swansea Bay promenade, carry rain protection for Mumbles and its seafront, and use removable layers inside the Maritime Quarter museums.

- 7–11°C
- Evenings
- 3–7°C

- Frequent rain and showers
- Daylight

Planning bands are the rounded 1991–2020 Mumbles Head mean daily maximum (9.09°C) and minimum (5.1°C), plus or minus 2°C. These bands are clothing prompts, not forecast limits or statistical confidence intervals. Mumbles Head is an exposed coastal station, so its wind and milder nights are not exact city-centre conditions. Inland Gower outings can differ. Check the forecast for your own dates. Monthly rainfall averages: 114 mm and about 16 days with at least 1 mm of rain.
