Why high UV levels matter
Officials have warned that strong UV radiation can cause sunburn, skin diseases, eye damage and long-term health problems. The risk is highest between 10 am and 3 pm, when sunlight is most intense.
People who spend long hours outdoors, including fishermen, delivery workers, tourists and transport staff, are especially at risk. Those with existing health conditions or weak immunity are also more vulnerable.
Heatwave adds to discomfort
Along with high UV levels, Kerala is also experiencing rising temperatures. A heatwave warning has been issued for parts of Thrissur and Palakkad districts.
Temperatures may reach up to 41°C in Palakkad and around 40°C in Thrissur, while several other districts are seeing temperatures between 36°C and 39°C. The combination of heat and humidity is making weather conditions uncomfortable across the state.
What weather changes are expected
The hot and humid conditions are likely to continue for the next few days. Most areas will remain dry, except for hilly regions, which may see slightly milder conditions.
High UV levels are common in tropical regions like Kerala and can remain strong even on clear days. Surfaces such as water and sand can reflect sunlight, increasing exposure further.
Simple precautions to stay safe
Authorities have advised people to avoid direct sunlight during peak hours and stay hydrated throughout the day. Wearing light cotton clothes, sunglasses, hats or using umbrellas can help reduce exposure.
Taking breaks in shaded areas, carrying water while travelling and avoiding dehydration-causing drinks like alcohol and excess caffeine are also recommended.
Extra care for vulnerable groups
Children, elderly people, pregnant women and those with health issues should take extra precautions. Schools have been advised to avoid outdoor activities during peak heat hours and ensure drinking water is available.
Outdoor workers are encouraged to adjust working hours and take regular breaks to avoid heat stress.
Fire risk and safety concerns
With rising temperatures, the risk of fire outbreaks in markets, buildings and waste areas has increased. There is also a possibility of forest fires in vulnerable regions.
Authorities have urged people to remain alert and follow safety guidelines to prevent accidents.
Monitoring and alerts in place
Real-time UV monitoring systems are active across the state, and warning systems such as sirens have been used in districts like Thrissur and Palakkad to alert residents.
Officials have advised the public to stay updated with weather alerts and follow official instructions to stay safe during this period.
