Movement and weather

Each season it is first heard regularly where daytime highs are around 18°C (typically 11 to 22°C, from 7 areas). That range is wide, so temperature alone does not explain when it turns up.

Over the weeks it was present in the past year, its centre in Europe ranged from 44°N in August to 54°N in June, about 1,100 km apart.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
