Movement and weather

Each season it is first heard regularly where daytime highs are around 16°C (typically 15 to 19°C, from 5 areas). That holds across 20° of latitude, which suggests its timing follows temperature more than the calendar.

Over the weeks it was present in the past year, its centre in Europe ranged from 48°N in May to 63°N in June, about 1,800 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.
