About weather.capetown

A hyperlocal weather and activity guide written by people who live in Cape Town. Updated every hour. Honest about the wind.

Why we exist

Generic weather services are bad at Cape Town. They tell you "Cape Town will be 24°C and partly cloudy" — a statement that's true and almost useless. The same conditions are a perfect day in Constantia and an unswimmable mess at Camps Bay. The same wind that closes the Table Mountain Cable Car is what kitesurfers fly across the world to find. The same overcast morning that ruins your hike is the cloud-bank that makes False Bay water 2°C warmer than yesterday.

weather.capetown was built to translate raw data into the only thing that matters: what should you do today, and where should you do it? Every page on this site is built around the local microclimate of a specific Cape Town neighbourhood, surf spot, or activity, with honest verdicts written by people who have actually lived through ten Cape Town summers. We don't do generic. We don't do "average highs in November." We tell you that the South Easter is gusting from Devil's Peak, that Camps Bay will be 35 km/h by 14:00, and that you should drive to Muizenberg if you want to swim.

Cape Town has a dozen weather systems, not one

The single most important fact about Cape Town's weather is that "Cape Town" doesn't have a weather. The peninsula has between eight and twelve distinct microclimates depending on how you count, separated by mountains and oceans that completely change the conditions over distances of two or three kilometres. A summer afternoon can deliver:

  • Camps Bay: 24°C, 8 km/h, perfect beach day.
  • Sea Point (3 km north): 22°C, 28 km/h, sand in your eyes.
  • Muizenberg (35 km south, over the mountains): 26°C, 12 km/h, water at 19°C, surfable.
  • Big Bay, Bloubergstrand (20 km north): 21°C, 35 km/h, glassy kitesurfing.
  • Stellenbosch (50 km east, beyond the mountains): 32°C, 6 km/h, vineyard heat.

All of those readings can be valid at the same moment. That's what we mean by hyperlocal.

How we work

Our live weather data comes from Open-Meteo, which aggregates feeds from the German Meteorological Service (DWD), the European Centre for Medium-Range Weather Forecasts (ECMWF), and the South African Weather Service (SAWS). For surf-specific information we cross-reference NOAA wave models and local surf reports. For tide we use the South African Navy Hydrographic Office. For climate averages we use SAWS climatological records back to 1961. We update site-wide weather every hour during daylight, every three hours overnight, and the activity verdicts every fifteen minutes from local stations.

The interpretation of that data — the activity verdicts, the neighbourhood guides, the "should you go" advice — is human. Our team includes a Cape Town-born meteorologist, a surf instructor with twenty years on the False Bay coast, a long-time travel writer who has covered the city for international publications, and an engineer who got tired of bad weather apps. Every page is written, fact-checked and signed by named human authors on our team.

How we decide a "verdict"

The little green-amber-red verdicts on the homepage are a deliberate translation, not a number. Each activity has its own thresholds — what makes a beach day good is not what makes a hike good. Our broad logic:

  • Beach day: wind under 20 km/h sustained, no swell warning, UV index 5+, no advisory water quality issue.
  • Mountain hike: visibility above 5 km, wind under 40 km/h on the plateau, no thunderstorm probability above 30%, temperature 12–28°C at altitude.
  • Surf: wave height 0.8–2.5 m at the spot, offshore or cross-shore wind, swell period above 8s.
  • Kitesurf: wind 15–30 knots sustained, side-shore or onshore direction, no thunderstorm risk.
  • Wine farms: air temperature 16–30°C in the relevant valley, no severe weather warning, no road closures.
  • Cable car: running per the official Table Mountain Aerial Cableway feed, wind under their operating limit.

The full thresholds, with rationale, are documented in our forthcoming methodology page. We adjust them as we learn — if we're calling "Go" on a day everyone tells us was miserable, we tighten. If we're calling "No" on a day Capetonians clearly enjoyed, we loosen.

The team

Sarah Botha — Lead writer, tourist content

Sarah was born in Cape Town, grew up in Pinelands, and has written about southern African travel for fifteen years, contributing to local and international publications including Getaway, Travel + Leisure and Wanted. She covers our visiting and neighbourhood pages and is responsible for the month-by-month tourist guides. Sarah is on the Atlantic seaboard most weekends and in the Winelands most weeknights.

David Mthembu — Meteorology & explainers

David holds a degree in atmospheric science from the University of Cape Town and worked at the South African Weather Service for eight years before going independent. He covers our explainer content (the Cape Doctor, microclimates, climate change) and reviews our forecast logic. David grew up in Khayelitsha and now lives in Observatory; he is the team's authority on what a cold front actually is.

Jess van Zyl — Activities, surf & outdoors

Jess has been teaching surfing at Muizenberg since 2008 and was a kitesurf instructor at Big Bay for over a decade before turning to writing full-time in 2024. She covers our activity pages, writes the spot guides, and is responsible for the conditions verdicts that make the homepage useful. Jess will not get out of bed for fewer than 18 knots.

Tariq Hendricks — Tech & data

Tariq is responsible for the data feeds, site infrastructure and forecast accuracy. He's a software engineer (ex-Yoco, ex-Naspers Labs) who got tired of bad weather apps and decided to build a better one. Tariq lives in Vredehoek and runs the local microclimate sensor network the site is gradually rolling out.

Our editorial standards

We have a public editorial policy covering accuracy, corrections, sources and conflict-of-interest disclosure. The headlines:

  • Every article has named human authors with relevant expertise; group articles are signed "By the weather.capetown team" and the contributing team members are listed on the about page.
  • We disclose data sources transparently on every page that uses them.
  • Errors are corrected publicly with a dated note at the bottom of the affected article.
  • We do not accept payment for editorial coverage. Affiliate links (when used) are disclosed at the point of recommendation.
  • We reach our own verdicts independently of advertisers. Display ads are programmatic; we don't choose who appears.

Our funding

weather.capetown is supported by display advertising (Google AdSense), affiliate commissions on a small number of Cape Town operators we trust, and a Friday-morning newsletter sponsorship programme. We may earn an affiliate commission if you book activities, accommodation or tours through links on this site — but we don't recommend operators we wouldn't use ourselves, and our editorial recommendations are not influenced by commission rates. Everything is disclosed at the point of recommendation, per our editorial policy.

The story behind the site

weather.capetown began as a private Slack channel in late 2024. Four friends — a meteorologist, a surf instructor, a writer and an engineer — kept asking each other the same questions ("is the wind up in Blouberg?" "is Muizenberg working?" "is Constantia hot today?") and getting answers that were better than any app. We started writing the answers down. We added a hyperlocal forecast layer to make the answers automatic. We turned it into a public site in April 2026 because we figured a few thousand other Capetonians and visitors were probably asking the same questions and getting the same useless generic forecast we had been getting.

We're still small. We update what we can, we get things wrong sometimes, we correct them publicly. If we miss your neighbourhood or your activity, tell us — we add coverage based on reader requests.

What's coming

  • More neighbourhoods. Clifton, Constantia, Hout Bay, Simon's Town, Stellenbosch, Hermanus and Franschhoek are next.
  • More activities. Hiking guides (Table Mountain, Lion's Head, the contour paths), wine tasting, whale watching, open-water swimming.
  • A live wind map. Custom-built for the Cape Peninsula with our growing sensor network.
  • A daily SMS service. One line of text at 06:30 with the day's verdicts. (In closed beta.)
  • The Cape Doctor index. A single 0–10 number describing how aggressively the south-easter is going to behave today.
