Movement and weather

Each season it is first heard regularly where daytime highs are around 29°C (typically 22 to 32°C, from 29 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 North America ranged from 30°N in December to 41°N in July, about 1,300 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.
