Movement and weather
Each season it is first heard regularly where daytime highs are around 19°C (typically 12 to 24°C, from 24 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.
| Region | First arrival | Last arrival | Typical peak | Areas |
|---|---|---|---|---|
| North America | 30 March 2026 | 5 October 2026 | 21 September 2026 | 24 |
