According to data from the Ukrainian Hydrometeorological Center published on Wednesday, the weather in the country is showing sharp fluctuations in temperature and atmospheric pressure, creating a difficult situation for residents of both major cities and rural regions. Forecasters warn that during the day, air temperatures will fluctuate between +26°C and +31°C, with brief spikes up to +34°C possible in some southern regions. ### Geography of heat and downpours: who is at risk? The weather map for August 17 shows a clear division of the country into two climatic zones. While the air in the south and central parts of Ukraine heats up to critical levels, the western and northern regions are preparing for precipitation. In particular, Kyiv and the Kyiv region are expected to have variable cloudiness with local brief rains and thunderstorms. A south-westerly wind blowing at 5–10 m/s will contribute to the movement of air masses, intensifying the atmospheric "seesaw" effect. Forecasters are paying special attention to regions where temperatures may exceed +34°C. This primarily concerns southern regions where the heat has not subsided for several days. Under such conditions, it is recommended to maintain a drinking regimen and avoid staying in the open sun during peak solar activity hours (from 12:00 to 16:00). ### Weekly forecast: from heat to cooling According to experts, the current heat is only a temporary phenomenon. By the beginning of next week, temperatures in some regions may reach +33°C, after which forecasters predict a sharp cooling. From the middle of the week, a drop in air temperature is expected, associated with the passage of a cold front. Such a sharp transition from heat to coolness may be a test for the cardiovascular system, especially for the elderly and those with chronic diseases. It is important to note that even in hot conditions, brief rains with thunderstorms are possible in some areas. This phenomenon is related to atmospheric instability and may lead to local flooding and infrastructure damage. Residents are advised to pay attention to weather warnings and take necessary precautions. ### Contradictory data While the Ukrainian Hydrometeorological Center forecasts moderate heat with temperatures up to +31°C, a number of sources, including TSN and Obozrevatel, report possible peaks up to +34°C in certain regions. This discrepancy may be due to differences in forecasting methodology and the time intervals for which the data are calculated. For example, some sources may take into account local microclimatic conditions that are not reflected in general forecasts. There is also uncertainty regarding the exact time of the onset of cooling. Some sources point to the middle of the week, others to the end of the week. This may be due to the variability of weather conditions and the complexity of long-term forecasting. In such cases, it is recommended to follow updates from official meteorological services. ### Recommendations for the population In conditions of heat and possible thunderstorms, it is important to follow safety measures. It is recommended to wear light clothing made of natural fabrics, use sunscreens and hats. In the event of a thunderstorm, avoid staying under trees and near tall objects. It is also important to monitor your health and seek medical help if necessary. For drivers and pedestrians in rainy and stormy conditions, it is recommended to observe traffic rules and be especially careful on the roads. If necessary, use hazard lights and do not leave vehicles unattended. ## 🔍 Fact-Check Verification - [Heat does not subside: where in Ukraine on August 17 it will be +34, and where thunderstorms will pass](https://tsn.ua/ru/ukrayina/zhara-ne-spadaet-gde-v-ukraine-17-avgusta-budet-34-a-gde-proydut-grozy-3149816.html) - Подтверждает наличие жары до +34°C и грозовых фронтов в отдельных регионах. - [After the heat, rains and thunderstorms are expected in several regions: weather forecast for August 17](https://24tv.ua/ru/prognoz-pogody-17-avgusta-2026-goda-kakaja-budet-temperatura_n3124425) - Подтверждает прогноз на 17 августа с указанием на дожди и грозы в нескольких областях. - [Heat does not subside: where in Ukraine on August 17 it will be +34, and in which regions thunderstorms will pass.
