On August 20, Ukraine will see genuinely hot weather: according to the Ukrainian Hydrometeorological Center, as cited by RBC-Ukraine, the air will warm up to +34° in some areas. At the same time, the hot day will not be completely cloudless and dry — in some regions, forecasters expect brief showers and thunderstorms. Thus, the heat, which has returned to the country after several cool days, is accompanied by a classic late-summer contrasting pattern: scorching heat during the day and localized heavy rainfall. ### Heat up to +34° and localized thunderstorms According to the forecast, the night will be mostly precipitation-free across the country, while during the day brief rain and thunderstorms are possible in places in northern Ukraine and in the Carpathians. It is precisely in these zones that hot air will meet moist air masses, forming convective clouds and brief downpours. In the rest of the country, hot and mostly dry weather will dominate, with thermometer readings peaking near +34°. ### Wind and gusts in the west and north During the day, the wind will be predominantly southwesterly at 7–12 m/s. However, in most western and northern regions, forecasters warn of localized gusts of up to 15–20 m/s. Such gusts are typically accompanied by thunderstorm fronts and can intensify the feeling of weather instability, especially in the afternoon hours. ### Weather in Kyiv and Kyiv Oblast In the capital and the oblast on August 20, variable cloud cover is expected. No precipitation is forecast for Kyiv itself, although during the day brief rain with thunderstorms is possible in places across Kyiv Oblast. For residents of the region, this means that the bulk of the precipitation will fall on suburban areas, while the city will remain hot and generally dry. ### Weekly trend: after the heat — a sharp cooling As forecasters previously reported, after several cool days the heat is returning to Ukraine, and at the start of the week temperatures reached +33° in places. The peak of this hot spell falls on the current days, with readings up to +34°. At the same time, from mid-week a sharp cooling and a noticeable drop in air temperature are forecast, which will end the current hot episode and return the country to a more moderate regime. ### Contradictory data When comparing publications from different outlets, a discrepancy is noted in the dates of the peak heat values. RBC-Ukraine and the Ukrainian Hydrometeorological Center tie the maximum of up to +34° to August 20, whereas TSN.ua in its headline points to +34° already on August 17, and KP.ua considers heat up to +34° in the context of the weekend. The numerical values (+34°, thunderstorms, wind gusts) match, only the specific day of the peak differs. This is because the hot period spans several consecutive days, and each outlet emphasizes its own "slice" of the week. As of August 20, the reference remains the forecast of the Ukrainian Hydrometeorological Center, relayed by RBC-Ukraine. ## 🔍 Fact-Check Verification - [Heat up to +34, rain with thunderstorms in places: what the weather will be like in Ukraine today](https://www.rbc.ua/ukr/news/speka-34-mistsyami-doshchi-grozami-koyu-bude-1787142806.html) - Основной источник: +34°, грозы на севере и в Карпатах, ветер 7–12 м/с с порывами 15–20 м/с, прогноз по Киеву.
