Between 2012 and 2025, VIIRS detected fire in 409 km² of Biombo at least once. In an average year it detected fire in 79 km², ranking 8th of 9 regions of Guinea-Bissau.
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 2020, with 107 km² detected; the quietest was 2021, with 53 km². The 2021–2025 average is 13% 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.
April, May and June together hold 71% of the fire-days in the record. The single busiest day was 20 May 2014, with detections in 14 cells.
Ground that burns again
Of the 409 km² with at least one detection, 39% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 155 | 38% |
| 2 years | 96 | 23% |
| 3 to 5 years | 115 | 28% |
| 6 to 10 years | 41 | 10% |
| 11 years or more | 1.2 | 0.3% |
The half-degree square with the most fire-days is centred at 11.75, -15.75 and holds 57% 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.
