Temperature Profile

• Average high: 25°C (77°F)

Daylight & Sun

• UV Index: Extreme (11+) — sunscreen non-negotiable

Rain & Wind

• Rainfall: Low (Mediterranean climate = dry summer). Average ~15 mm / 3–4 light shower days.
• Cape Doctor: Strong SE trade wind. Clears pollution, cools temps, creates tablecloth cloud on Table Mountain. Can howl 50–80 km/h for days.
• Thunderstorms: Rare but possible—inland/evening.

What to Pack

• Light layers (t-shirts, shorts, light dresses)
• Light jacket/sweater for evenings (wind chill)
• Swimwear + quick-dry towel
• Windbreaker (essential for Cape Doctor days)
• Hat, sunglasses, SPF 50+
• Comfortable walking shoes + sandals

Best December Activities

• Beaches: Clifton, Camps Bay, Llandudno, Boulders (penguins), Muizenberg (surf)
• Table Mountain: Cableway or hike (start early—heat, wind, crowds)
• Winelands: Stellenbosch, Franschhoek, Constantia (harvest season energy)
• Cape Peninsula: Chapman's Peak, Cape Point, Boulders—full day loop
• Kirstenbosch: Summer sunset concerts (Sundays)
• Festivals: Cape Town Minstrel Carnival (Jan 2, but prep in Dec), NYE fireworks V&A Waterfront

Crowd & Cost Reality

• Peak season pricing: accommodation +30–100%
• Book restaurants, car rental, Table Mountain tickets weeks ahead
• Traffic: Severe on peninsula routes (Chapman's Peak, Ou Kaapse Weg) weekends

December is Cape Town at its postcard best—if you plan ahead and respect the wind.
