The ozone level on the island has reached the alert level.

On August 16, 2026, ozone levels at the measurement site in Otlica above Ajdovščina reached the warning threshold, prompting health authorities to advise residents to avoid outdoor activity. According to data released by the Slovenian Environment Agency (Arso), the hourly ozone concentration hit 180 micrograms per cubic meter at 2 p.m., exceeding the alert level. The average eight-hour ozone reading during the day was 157 micrograms per cubic meter. These measurements apply to a broader area surrounding Otlica. The high ozone readings are attributed to intense sunlight and elevated temperatures, which typically occur between 1 p.m. and 5 p.m. During this period, ozone concentrations tend to rise significantly. Health officials have warned that such conditions can irritate respiratory systems and exacerbate existing health issues. As a result, Arso has issued recommendations for individuals with chronic respiratory conditions or circulatory disorders to remain indoors during these hours. The agency also advised healthy individuals to limit physical exertion outdoors, especially in elevated areas where ozone levels are often higher. This guidance aligns with advice from the National Institute of Public Health (NIJZ), which recommends that residents monitor air quality forecasts and alerts regularly. The institute emphasized the importance of ventilating indoor spaces during early mornings and late nights to maintain better air quality. Health experts noted that ozone levels are likely to decrease in the evening, with lower concentrations expected on Monday. However, they cautioned against assuming a return to normal conditions too soon. The National Institute of Public Health reiterated its recommendation that people avoid prolonged exposure to the sun and physical activities during peak ozone hours. It also suggested that individuals should stay informed about daily updates from Arso regarding air quality. Residents in the region were urged to take precautions, particularly those who are more vulnerable to environmental factors. The advisory included specific times, between 1 p.m. and 5 p.m., when ozone levels are highest. During these hours, the risk of irritation to the respiratory system increases, making it advisable to minimize time spent outside. For those who must go outdoors, wearing protective masks could offer some degree of relief. In addition to advising caution, local health authorities stressed the importance of maintaining good indoor air quality. They recommended regular ventilation during cooler parts of the day and avoiding the use of products that might contribute to indoor pollution. These measures aim to create safer environments for all residents, especially during periods of heightened air pollution. The situation highlights the ongoing challenges posed by seasonal weather patterns and their impact on public health. While the immediate concern is the current spike in ozone levels, long-term strategies for managing air quality remain essential. Local agencies continue to monitor conditions closely and will provide further updates as necessary. Residents are encouraged to follow official guidelines and make adjustments to their routines accordingly.
