Turkiye: High temperatures forecast nationwide through at least April 27

Forecast models indicate that high temperatures will persist across much of Turkiye through at least April 27. As of April 23, the General Directorate of Meteorology has warned that temperatures are forecast to rise above the seasonal normals across much of the country over the coming days. Temperatures are expected to rise to around 4-6 C (7-11 F) above seasonal normals in the Marmara, Aegean, and western Mediterranean regions and 10-15 C (18-27 F) above seasonal normals in the eastern Mediterranean, Central Anatolia, Black Sea, and Eastern and Southeastern Anatolia regions. The highest temperatures are likely in southern parts of the country, with highs of around 37-38 (99-100 F) possible in Adana Province over the coming days and 35-37 (95-99 F) in Osmnaiye and Sanliurfa. Highs of around 24-36 C (75-97 F) are expected across much of the rest of the country.

The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke. Authorities have advised the public, especially those with chronic diseases, the elderly, and children, to avoid being outdoors during the hottest parts of the day.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the affected areas. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
