Between 2012 and 2025, VIIRS detected fire in 271 km² of Nairobi at least once. In an average year it detected fire in 46 km², ranking 8th of 8 regions of Kenya.
Year by year
Detected area per year, km². Area of 0.01° cells with at least one detection in the year.
The busiest year was 2015, with 60 km² detected; the quietest was 2024, with 19 km². The 2021–2025 average is 26% lower than the 2012–2016 average.
Through the year
Share of all fire-days 2012–2025 by month. A fire-day is one cell with a detection on one day.
January, February and March together hold 41% of the fire-days in the record. The single busiest day was 10 June 2023, with detections in 8 cells.
Ground that burns again
Of the 271 km² with at least one detection, 21% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 157 | 58% |
| 2 years | 56 | 21% |
| 3 to 5 years | 31 | 11% |
| 6 to 10 years | 20 | 7.3% |
| 11 years or more | 7.4 | 2.7% |
The half-degree square with the most fire-days is centred at -1.25, 36.75 and holds 97% of the region's fire-days.

- How these figures are madeDetected area, cells, and the single-satellite record.
Detected area counts every 0.01° cell with at least one VIIRS detection, so a small fire counts as a whole cell and a fire missed by cloud or between passes is absent. Borders: Natural Earth 1:10m. 2012 begins on 20 January.
