Cape Town summers are a dream—until the temperature creeps past 30°C and the city feels like it’s melting into the ocean.

Heat waves have become increasingly common, with long stretches of dry, relentless heat affecting everything from daily routines to weekend plans. Whether you’re a local trying to survive the commute or a visitor determined to make the most of your trip, a little preparation goes a long way. This is your practical, no-panic guide to surviving a Cape Town heat wave comfortably, safely, and with your sanity intact.
Master the timing of your day
When the heat is intense, when you do things matters just as much as what you do. Early mornings and late afternoons are your best friends. Plan walks, workouts, errands, and sightseeing before 10am or after 5pm, when the sun is less aggressive. Midday—especially between 12pm and 3pm—is best reserved for indoor activities, shaded lunches, or a well-earned nap.
If you’re outdoors, seek out tree-lined streets, coastal promenades, or spots with natural airflow. Even a light sea breeze can make a noticeable difference.
Hydration is non-negotiable
Cape Town heat is dry, which means dehydration can sneak up on you faster than expected. Sip water consistently throughout the day rather than waiting until you feel thirsty. Adding electrolytes—whether through sports drinks, coconut water, or a pinch of salt and citrus in your water—can help replace what you lose through sweat.
Limit alcohol and excessive caffeine during peak heat hours. A cold beer may feel tempting, but it dehydrates you further and increases the risk of heat exhaustion.
Dress for survival, not style (mostly)
Lightweight, breathable fabrics like cotton, linen, and bamboo are essential during a heat wave. Loose-fitting clothes allow air to circulate and help sweat evaporate more efficiently. Light colours reflect heat, while dark shades absorb it, save the black outfit for cooler evenings.
A wide-brimmed hat, UV-protective sunglasses, and sunscreen with a high SPF aren’t optional. The Cape sun is harsh, and sunburn not only damages skin but also makes it harder for your body to regulate temperature.
Keep your home cool without cranking the power
Not everyone has air conditioning—and even if you do, constant use can be expensive and unsustainable. Close curtains and blinds during the hottest parts of the day to block out direct sunlight. In the evening, open windows on opposite sides of your home to create cross-ventilation and let cooler air flow through.
Fans work best when paired with an open window or a bowl of ice placed in front of them. Switching off unnecessary lights and appliances also helps reduce indoor heat buildup.
Eat light and smart
Heavy, hot meals can raise your body temperature and make the heat feel more intense. Opt for lighter foods like salads, grilled vegetables, fruit, smoothies, and cold soups. Water-rich foods—think watermelon, cucumber, berries, and oranges—help with hydration while keeping meals refreshing.
If you’re cooking, use the microwave, air fryer, or outdoor braai instead of the oven to avoid heating up your kitchen unnecessarily.
Use the city’s natural cooling spots
Cape Town is lucky to have built-in heat escapes. Tidal pools, beaches, dams, and shaded parks offer instant relief when the temperature spikes. Even a short dip can lower your body temperature and boost your mood.
If swimming isn’t an option, air-conditioned spaces like libraries, museums, cinemas, and shopping centres can provide a safe place to cool down during extreme heat days.
Know the warning signs
Heat exhaustion and heat stroke are serious and can escalate quickly. Watch out for dizziness, nausea, headaches, rapid heartbeat, confusion, or excessive fatigue. If symptoms appear, move to a cool area immediately, drink water, and rest. Seek medical help if symptoms worsen or don’t improve.
Check in on children, older adults, pets, and anyone with chronic health conditions—they’re more vulnerable during heat waves and may need extra support.
Pace yourself and be kind
Finally, adjust your expectations. Productivity may dip, plans may slow down, and that’s okay. Heat waves aren’t the time to push yourself to the limit. Rest when you need to, move gently, and prioritise your wellbeing.
Surviving a Cape Town heat wave isn’t about suffering through it—it’s about adapting. With smart timing, hydration, cooling strategies, and a little grace for yourself, you can ride out even the hottest days and still enjoy everything summer in the Mother City has to offer.
