Movement and weather

Each season it is first heard regularly where daytime highs are around 28°C (typically 27 to 29°C, from 5 areas). That holds across 25° 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 North America ranged from 13°N in April to 22°N in September, about 1,000 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.
