Movement and weather

Each season it is first heard regularly where daytime highs are around 24°C (typically 20 to 32°C, from 7 areas). That range is wide, so temperature alone does not explain when it turns up.

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.
