Is Indian summer coming soon to Moscow and how hot will it be?

Indian summer in the Moscow region typically arrives in September, when after the autumn rains, warm and sunny weather sets in for a few days. You can't predict the exact timing and temperatures ahead of time - it depends on atmospheric conditions that form over the course of the month. If you're planning something outdoors, it's better to check the forecast a week ahead: Indian summer can be mild or quite hot, but it doesn't last long.

We already had several days in September this year with heat around thirty degrees, then it suddenly got cold - that's exactly what Indian summer is, when it warms up after the rain. It's hard to predict temperatures because a forecast two weeks ahead is basically like reading tea leaves, especially when it comes to autumn with all its temperature swings.

Practical advice: the transition period is stressful for your body, so dress in layers that you can easily take off or put on. I bring a thin sweater with me even when it's hot during the day, because by evening the air can cool down dramatically. And check the forecast just a day or two ahead instead of long-term - that way you'll actually know what to change into in the morning before you head out.

The main thing to understand is that this isn't a meteorological forecast - it's just the name of a weather phenomenon that might not happen at all or could occur at a completely different time than expected. I wouldn't prepare for specific dates and temperatures; I'd just keep lightweight clothes in the closet for any occasion. In September, Moscow can still be warm and summery, and that's normal. Sharp changes in weather are inevitable anyway.
