Moscow weather outlook for late August
The city of Moscow experienced a significant rain event on August 4 and 5, 2025, with the potential to pour down a month's worth of rain in just two days. According to Evgeny TISHKOVETS, a leading specialist at the Center for Weather "Fobos", this rain was a megadownpour.
The rainfall was caused by a pattern of torrential rains, associated with persistent storms, lightning, and strong winds. This suggests a slow-moving or stalled weather system that produced multi-day rainfall. Tatyana POZDNYAKOVA, the chief specialist at the Moscow Weather Bureau, explained that this system was a cyclone with a complex system of atmospheric fronts.
City storm drains, designed for 10-15 mm of rain per day, struggled to cope with the abnormal and prolonged rainfall. Even the most advanced and well-maintained drains may not have been able to handle the deluge, TISHKOVETS admitted.
The rain will continue into Tuesday, August 5, but at a lesser intensity compared to the previous days. By August 9, conditions had improved with just passing clouds and cooler temperatures. The forecasts do not indicate continued heavy rain beyond early August for Moscow.
The current rain event was not expected to be fast or sudden, but rather a longer event. In fact, some weather stations in the Krasnodar region recorded 171 mm of precipitation in 24 hours, indicating the intensity of the rainfall. However, there are no specific details about a large-scale frontal system or tropical influence directly over Moscow for those exact dates.
Residents of the capital saw an unusual sight during the rainstorm - the image of a pig in the cyclone. Almost 80 liters of water per square meter could fall in Moscow due to the current rain, making it a significant event for the city.
In summary, the heavy rain on August 4-5, 2025, in Moscow was a result of a persistent storm pattern involving torrential rains, lightning, and strong winds. This pattern likely represented a slow-moving or stalled weather system causing multi-day rainfall. By August 9, conditions had improved, and the heavy rain event was not expected to continue long past early August.
The intensity of the rainfall observed in Moscow from August 4 to 5, 2025, was so heavy that it was categorized as a megadownpour by Evgeny TISHKOVETS, a leading weather-forecasting specialist at the Center for Weather "Fobos". Despite the aftermath of the deluge, the weather-forecasting for Moscow did not indicate continued heavy rain beyond early August.
