Lake in Summer Palace of Beijing opened for skating this week (ice, average)

Probably very few megacities in the world have this.

I'm surprised the ice is thick enough to hold that many people. It doesn't look that cold in Beijing right now, with highs above freezing.

Beijing is just consistently cold, though not too cold.
If the average temperature is below freezing every day, the ice will be thick enough after a few weeks.
