Meteo e acqua

Un clima mediterraneo con estati secche, inverni piovosi e un approvvigionamento idrico che richiede attenzione. I numeri ti dicono quando visitare e perché le dighe contano.

Climate type

  Cape Town's climate is its defining asset. A Mediterranean climate with dry, warm summers (December to February, 25–30°C) and mild, wet winters (June to August, 8–18°C). The city averages 3,100 hours of sunshine per year. Rainfall is concentrated in winter, with June and July each receiving over 80 mm. The South-Easter wind (the "Cape Doctor") blows strongly in summer, clearing pollution but testing patience.

Livelli delle dighe: il numero che determina tutto

Cape Town's six major dams supply the city. After the 2017-2018 drought nearly brought "Day Zero", dam levels are watched closely. The current combined level sits at 73,0%.

Green = healthy (70%+). Gold = adequate (50-70%). Red = low (<50%).

Key takeaway. Theewaterskloof holds over half the total capacity. When it drops, the city feels it. Combined levels below 50% trigger stricter conservation measures.

Precipitazioni: il 49% cade in tre mesi

Le precipitazioni di Città del Capo sono fortemente stagionali. Giugno, luglio e agosto forniscono quasi la metà del totale annuale. I mesi estivi sono quasi secchi, ecco perché le riserve delle dighe accumulate in inverno devono durare.

Red = peak winter rainfall. Gold = transitional months. Blue = dry summer.

Key takeaway. Winter (June to August) delivers 49% of the annual total. Summer months are near-dry, which is why dam levels matter so much by late summer.

Temperature: calde ma mai tropicali

Le massime estive raggiungono i 28°C, raramente di più. Le minime invernali si aggirano sui 7-8°C. L'assenza di umidità rende entrambi gli estremi confortevoli. Febbraio e marzo offrono il miglior equilibrio tra caldo, vento leggero e prezzi bassi.

Red = hot summer peaks. Gold = pleasant shoulder months. Blue = mild winter.

Key takeaway. February to March is the sweet spot: warm days (27–28°C), lighter winds, fewer crowds, and accommodation prices drop after the December peak.

Frequently asked questions

When is the best time to visit Cape Town?

Late summer to early autumn (February to April). Warm weather, calmer winds, fewer tourists, and lower prices. December and January are peak season with crowds and high prices.

Does it rain a lot in Cape Town?

515 mm per year, concentrated in winter (June to August). Summer months average under 20 mm. Pack a rain jacket for winter visits, but don't expect London-style drizzle year-round.

What is the South-Easter wind?

Known locally as the "Cape Doctor", this strong south-easterly wind blows from October to March. It clears pollution and keeps the air fresh, but can make beach days uncomfortable. Sheltered spots like Camps Bay are less affected.

Should I worry about water shortages?

The 2017–2018 drought brought Cape Town close to "Day Zero". Dam infrastructure has since been supplemented, but water remains precious. Check current dam levels on this page and respect local conservation efforts.
