What happened
- 7-day mean to 2 October 2026
- 93
- That day alone: 111
- 5-year median, same week
- 78
- Change
- +16
- Change, per cent
- +21%
Why it matters
Daily figures mostly reflect the weather, so the observatory compares the mean of the last seven days with the same week in up to five earlier years. A breach means this week sits well outside what those years would lead you to expect, and by at least 15%. It is reported when an unusual run begins and for the latest day while it lasts, not every day.
For average air quality index, lower is better. This movement is therefore assessed as a deterioration.
Historical context
Same week in earlier years: 2025 75, 2024 74, 2023 128, 2022 92, 2021 78. Daily values are compared as 7-day means because a single day mostly reflects weather.
