NSRI urges water users to exercise caution during the heatwave.
NSRI urges water users to exercise caution during the heatwave: Cape Town, Tuesday, 10 March 2026 – The National Sea Rescue Institute (NSRI) is urging the public to exercise caution around water during the current heatwave affecting Cape Town and parts of the Western Cape.
The South African Weather Service (SAWS) has issued a heatwave advisory for the Western Cape, including the Cape Town region, expected to persist from Monday, 9 March until Friday, 13 March. Temperatures are forecast to rise significantly above the seasonal average, with some areas experiencing temperatures in the mid-30s to low-40s°C.
Hot weather often draws large numbers of people to beaches, rivers and dams to cool off. While spending time in and around water can be enjoyable, it also increases the risk of drowning incidents if basic safety precautions are not followed.
The NSRI encourages water users to choose beaches where lifeguards are on duty and to swim between their red and yellow flags. Lifeguards monitor water conditions and can quickly respond if someone needs help.
Parents and caregivers are reminded to watch children closely at all times around water. Drowning can happen quickly and silently. Young children should never be left unattended near water.
During extreme heat it is also important to stay well hydrated. Drink plenty of water throughout the day and avoid waiting until you feel thirsty. Dehydration can lead to fatigue, dizziness and poor judgement, which can increase the risk of accidents in and around the water.
Alcohol and water activities are a dangerous combination. The NSRI strongly advises against swimming, boating or participating in water activities after consuming alcohol, as alcohol impairs judgement, balance and reaction time.
Beachgoers should also remain aware of rip currents, which are strong channels of water flowing away from the shore. If caught in a rip current, do not panic and do not try to swim directly back to shore. Instead, remain calm, float if necessary and swim parallel to the shoreline until you are out of the current, then make your way back to the beach. Raise your arm and call for help if needed. Never go into the water to try and help a person in difficulty without first calling for help and taking something that floats with you. That could be a Pink Rescue Buoy or a surf board.
Those visiting rivers and dams are reminded to be cautious of slippery banks and sudden drop-offs.
Always supervise children closely and ensure that everyone on boats or paddle craft wears a lifejacket.
The NSRI also reminds the public that rescue services should be contacted immediately if someone appears to be in difficulty in the water.
“During hot weather we often see increased activity at beaches, rivers and dams,” NSRI Communications manager, Andrew Ingram said. “A few simple precautions can make the difference between having fun and a tragedy.”
Water users are encouraged to buddy up, look out for one another, respect local safety signage and follow the guidance of lifeguards.
The NSRI wishes everyone a safe and enjoyable time on the water during the current heatwave.
