Moscow's early heatwave sparks climate concerns as summer arrives ahead of schedule

Moscow is facing unusually warm weather far earlier than expected, with meteorological summer typically arriving around May 25. While the city has already broken temperature records, experts caution that it remains unclear whether the entire season will bring relentless heat. Global climate change is playing a clear role in the rising temperatures. Residents were first warned of chaotic weather patterns in early April. Despite this, the current warmth has surprised many, as summer conditions in Moscow usually don't set in until late May. The recent snowmelt from a heavy winter has increased soil moisture, which could influence how the season unfolds.

Weather forecasters have not ruled out heatwaves with abnormally hot and dry spells this summer. However, they stress that summer weather in the city often behaves independently of spring or winter conditions. While recent years have seen July daytime highs averaging 23–25°C, historical comparisons over the past two decades remain unavailable. The possibility of scorching, dry periods still exists, but predictions for the full season remain uncertain. Soil moisture from winter snow may offer some relief, though its long-term impact is hard to gauge. For now, Muscovites are being advised to prepare for potential swings between extreme heat and more typical summer conditions.
