Heat and UV in Cyprus: warnings and safety advice
How to interpret heat warnings and the UV index in Cyprus, plan your day and recognise conditions requiring urgent medical attention.
Checked: 23 September 2026.
Temperature and UV — different risks
Heat puts a strain on the body’s temperature regulation system, whilst ultraviolet radiation damages the skin and eyes. These risks are linked to the sun but are not the same: high UV levels are possible in windy conditions and at moderate temperatures, whilst dangerous heat stress can occur in the shade, in a humid room or during strenuous work. Therefore, the two indicators are assessed separately.
Temperature is assessed in conjunction with the time of day, location, humidity, wind and the nature of the physical exertion. The Met Office issues warnings for different areas of the island: inland areas, the coast and the mountains may have different thresholds and times when warnings are in effect. The figure for Nicosia cannot be automatically applied to Troodos or the coast.
The UV index is an international scale measuring the level of solar ultraviolet radiation at the surface. It does not indicate temperature, nor does it specify the length of time one can safely spend in the sun. The higher the index, the sooner you need comprehensive protection: shade, clothing, a hat, sunglasses and sun cream for exposed skin.
How to interpret the warning
A yellow alert indicates potentially hazardous weather and the need to monitor updates and avoid unnecessary risks. Orange indicates dangerous, unusual conditions and a likelihood of harm to health. Red describes an extremely dangerous event: follow all instructions from the authorities and prepare for exceptional measures.
Read the start and end times, the affected area, and the forecast for the daytime high and night-time low. A warm night prevents the body from recovering, so the risk does not end at sunset. If the warning has been updated, the new message replaces the old one; a screenshot without the date and area is unsuitable for planning.
You need the forecast before heading out: reschedule your journey, exercise and work for cooler times of day, and find an air-conditioned place and water in advance. This notification is not a personal medical assessment. People with chronic conditions or taking medication that affects fluid balance or heat regulation should check their plans with their doctor.
Daily plan for hot weather
In 2026, the Ministry of Health advised avoiding prolonged exposure to the sun, particularly between 11:00 and 17:00, limiting strenuous activity and staying in cool, shaded or air-conditioned places. Early morning is generally better, but taking precautions and listening to how you feel are still more important than sticking to your usual routine.
Drink regularly, without waiting until you feel very thirsty, unless your doctor has restricted your fluid intake. Alcohol and excessive caffeine are no substitute for water. Light, loose-fitting clothing, a wide-brimmed hat and sunglasses reduce exposure, but do not allow you to stay out in the heat indefinitely.
Keep your home cool by shading the windows, airing it out at night when it’s cooler outside, and using a properly working air conditioner. A fan circulates the air but doesn’t always provide sufficient cooling in extreme heat. Never leave a child, an elderly person or a pet in a parked car, even for a few minutes.
Protection from UV rays
The World Health Organisation recommends combining different methods of protection rather than relying solely on sun cream. Seek out dense shade, cover your skin with clothing, wear a hat that protects your face and neck, and sunglasses with UV filters. Umbrellas and clouds reduce, but do not eliminate, scattered and reflected radiation.
Apply a broad-spectrum sunscreen with an SPF of at least 15 – preferably higher – to exposed areas, and reapply approximately every 2 hours, as well as after swimming, sweating or towelling off. SPF is not a multiplier of the time you can spend in the sun and does not compensate for areas missed.
Children in particular need shade, clothing and a structured daily routine; infants should not be kept in direct sunlight. UV rays reflect off water, and a cool breeze can mask the sensation of the skin heating up. Medicines and cosmetic treatments may increase sensitivity: check with your doctor or pharmacist about any such restrictions before travelling.
Who is most at risk
Infants, young children, the elderly, pregnant women, people with reduced mobility, those living alone and those working in hot conditions require particular attention. Those at risk also include people with cardiovascular, respiratory or kidney conditions, diabetes, obesity and conditions that make self-care difficult.
Arrange to check in with them in the morning and evening; ensure they have a cool room, water and their medication. Do not advise them to drink more without medical advice if they have heart or kidney failure: fluid intake should be determined by a doctor. The employer should plan for breaks, shade, water and acclimatisation, rather than shifting the responsibility onto the employee.
Tourists need the address of their accommodation, the emergency number 112, insurance details and a list of their medication. On a trail or at the beach, it takes longer for help to arrive, so the threshold for seeking help should be lower. The combination of heat, dust, alcohol, lack of sleep and physical exertion is more dangerous than any single factor on its own.
Heat exhaustion and heatstroke
Early signs may include intense thirst, a dry mouth, headache, weakness, dizziness, nausea, cold clammy skin, and a rapid pulse or breathing. Move the person to a cool place, remove any excess clothing, cool them with water or cold compresses, and give them small sips of water only whilst they are conscious.
Heatstroke is a life-threatening condition. A body temperature above 40 degrees, hot, red, dry skin, confusion, slurred speech, convulsions or loss of consciousness require an immediate call to 112. Continue cooling the person until help arrives and do not give anything to drink to someone who is unconscious.
The absence of dry skin does not rule out a serious condition, particularly during physical exertion. Do not cool the person down with alcohol and do not delay calling for help whilst taking measurements. If symptoms of exhaustion persist or worsen, a medical assessment is required; this information does not replace personal advice from a doctor.
Check before heading out
Check the official weather service warnings, hourly temperatures and the UV index for your location. Plan your return time, locate shade, ensure you have a supply of water and identify the nearest cool place. For the seaside, check the flags and lifeguard hours; for hiking trails, check trail closures and fire risk.
Take water, a hat, sunglasses, protective clothing, sun cream, a fully charged mobile phone and any prescribed medication. Adjust your activity level if there is no shade, or if someone has not slept well, is unwell or is not yet acclimatised to the climate. Check on children and the elderly regularly: they do not always report symptoms in good time.
