Moscow’s Coldest Summer Period on Record? 15 Consecutive Days with Maximum Temperatures only +15/+23°C

Moscow has just recorded probably its coldest late June period on record, marked by an unusually long stretch of mild and cool weather. Between June 18 and July 2, 2025, the city experienced 15 consecutive days with maximum temperatures ranging only between +15°C and +23°C—significantly below the seasonal average.

This extended cool spell contrasts sharply with Moscow’s typical warm and sometimes hot early summer climate. The persistent lower temperatures have impacted daily life, with residents noting the lack of typical summer heat, affecting outdoor activities and energy consumption patterns.

Meteorologists attribute this unusual pattern to a stable weather regime dominated by cooler air masses and limited solar heating, possibly influenced by broader atmospheric circulation anomalies over the region, including Cyclone Ziros occurrence.

The record-breaking cool late June serves as a reminder of the variability and complexity of weather, even amid ongoing global warming trends. It also raises questions about potential impacts on agriculture, tourism, and urban comfort in the Russian capital during what is normally a warm and vibrant time of year.
