Ukrainian meteorologists said abnormal heat will return to the country starting Wednesday, July 29 [2].

This sudden shift in weather follows a cooler spell and poses risks to public health and agriculture across the region. The return of extreme temperatures disrupts the stability of the current seasonal transition.

According to the Ukrainian Hydrometeorological Center, a high-pressure system is moving from Western Europe, specifically affecting Spain, France, and the UK, bringing hot, dry air masses into the region [5, 6]. These shifting atmospheric fronts are the primary drivers of the temperature rise [6].

Forecasts vary regarding the intensity and timing of the heat. One report said temperatures will rise to 35°C during the upcoming weekend [3]. Other data from Ukranews suggests a different timeline, noting a heat return starting July 16 with maximum temperatures reaching 31°C [4, 7]. During that earlier period, daytime temperatures were estimated between 23°C and 28°C, while night temperatures hovered around 16°C [5].

The heat is expected to affect the entire country, though precipitation patterns will differ by region. Northern and central oblasts, including Kyiv and Chernihiv, are expected to see rain [1]. Conversely, the southern and eastern regions are forecast to remain dry [1].

Meteorologists said the anomalous heat and dry weather were expected as early as mid-July [8]. The current movement of air masses suggests that the most intense heat will peak over the coming days as the high-pressure system settles.

Abnormal heat will return to the country starting Wednesday, July 29.

The return of abnormal heat in late July indicates a volatile atmospheric pattern driven by European high-pressure systems. The discrepancy between forecast dates and peak temperatures suggests a fluctuating weather front, meaning the region may experience rapid oscillations between rain and extreme heat, complicating agricultural planning and energy demand for cooling.
