Summer in Dubai is not just hot, it is a season that changes how you plan your whole day. With careful timing, steady hydration and respect for warning signs, most people can still work, exercise and enjoy the city safely. The key is not to treat a summer afternoon like a winter one. Preparation, and a willingness to stop early, makes a real difference.
Choose the safest hours to be outside
The best windows for outdoor activity in summer are generally early morning and evening, after the sun has lost its peak strength. A walk, run or cycle ride that feels pleasant at dawn can become risky by late morning, even for fit adults. Plan exercise, beach time and outdoor errands around those cooler windows, and build in shade and rest stops rather than pushing through.
Between late morning and mid-afternoon, move activities indoors where you can. If you must be outside, wear a hat, sunglasses and sunscreen, choose loose, light-coloured clothing, and reapply sunscreen after swimming or sweating. Check the forecast and any official weather warnings before you set out.
Hydration and electrolytes
Do not wait until you feel very thirsty to drink. In Dubai’s heat you can lose fluid quickly through sweat, sometimes before you notice it. Keep water with you at home, at work, in the car and during exercise, and drink regularly in small amounts through the day. For longer or more intense activity in the heat, drinks or foods that replace salts as well as fluid can help, because sweat contains electrolytes such as sodium and potassium.
- Start the day hydrated and keep a refillable bottle within reach
- Drink regularly during activity, not only when you stop
- Replace salts after prolonged sweating, especially after exercise
- Limit very sugary drinks and be cautious with caffeine and alcohol in the heat
- Encourage children to drink even when they say they are not thirsty
Signs you may not be drinking enough include a dry mouth, dark urine, headache, tiredness and dizziness. Treat those as a signal to stop, find shade or air conditioning, and rehydrate steadily. If symptoms do not improve, get medical advice rather than trying to carry on.
Heat exhaustion and heatstroke: know the difference
Heat exhaustion usually develops gradually. Warning signs can include heavy sweating, feeling weak, dizzy or nauseous, a headache, pale or clammy skin, and a fast pulse. Move the person to a cool place, loosen clothing, cool the skin with water and fanning, and give small sips of water if they are fully conscious. If they vomit, feel worse, or do not improve within about thirty minutes, seek medical help promptly.
Heatstroke is a medical emergency. It can follow untreated heat exhaustion or develop quickly during intense activity in extreme heat. Warning signs include a very high body temperature, hot and red skin that may be dry, confusion, agitation, slurred speech, seizures or loss of consciousness, and a rapid pulse. Call for emergency help immediately on 998 for an ambulance or 999 in an emergency, move the person to the coolest place available, and cool them rapidly with water and fanning while you wait. Do not give fluids to someone who is confused or unconscious.
Children, older people and higher-risk groups
Children overheat faster than adults and may not recognise or report early symptoms, so adults need to set the limits for them. Never leave a child, or a pet, in a parked car, even briefly and even with a window open. Plan shade, drinks and indoor breaks into every outing, and watch for unusual tiredness, irritability or complaints of headache and nausea.
Older residents, pregnant women, and people with long-term conditions, or who take medicines that affect fluid balance or temperature control, should take extra care and follow their doctor’s advice. Check in on neighbours and relatives during heatwaves, especially anyone living alone.
Outdoor work and the midday break
For people who work outdoors, rest, shade and water are not optional extras. The UAE has a summer midday break rule, administered in general by the Ministry of Human Resources and Emiratisation, which restricts outdoor work under direct sun during the hottest middle hours over the summer months. Exact dates, hours and exemptions are set each year, so check the current official announcement.
Whatever your job or plans, the principle is the same: respect the heat, plan around it, and act early on warning signs. Dubai’s summer is manageable when you work with the climate, not against it.
