Very strong heat stress expected. Risk of overheating and dehydration. Significantly increased load on the healthcare system and social services (especially care for the elderly and chronically ill). Decline in worker performance and increased risk of occupational accidents, particularly in outdoor work or in stuffy enclosed environments.
Český TěšínAvoid prolonged exposure to the sun or overheated urban areas, strictly maintain hydration with increased intake of non-alcoholic beverages (including mineral replenishment), avoid higher physical/mental loads, ventilate only during cooler parts of the day (usually early morning). Seek medical help in case of health problems. Do not leave children or animals in parked vehicles. Set air conditioning in rooms or vehicles so that the body is not exposed to excessive thermal shock when moving in or out; the difference between indoor and outdoor temperatures should not exceed 5 to 8 °C.CHMI, Tomáš Mejstřík30/07/2026, 13:16

Maximum air temperatures above 32 °C. Possible complications, especially in transport, livestock production, and the energy industry. Possible deformation of rails in rail transport, damage to poor quality roads, particularly those exposed to sunlight. The need for intensive cooling of enclosed halls (livestock production, industry, logistics, etc.). Higher load on energy infrastructure.
Český TěšínCheck the functionality of the cooling systems and backup power systems. When travelling, monitor the traffic situation.CHMI, Tomáš Mejstřík30/07/2026, 13:16
