Movement and weather

Each season it is first heard regularly where daytime highs are around 29°C (typically 28 to 30°C, from 8 areas). That holds across 55° 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 South America ranged from 17°S in March to 5°N in November, about 2,500 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.
