Between 2012 and 2025, VIIRS detected fire in 491 km² of Heredia at least once. In an average year it detected fire in 57 km², ranking 6th of 7 regions of Costa Rica.
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 2024, with 95 km² detected; the quietest was 2021, with 35 km². The 2021–2025 average is within 5% of 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.
February, March and April together hold 54% of the fire-days in the record. The single busiest day was 31 March 2024, with detections in 11 cells.
Ground that burns again
Of the 491 km² with at least one detection, 14% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 320 | 65% |
| 2 years | 100 | 20% |
| 3 to 5 years | 62 | 13% |
| 6 to 10 years | 6.1 | 1.2% |
| 11 years or more | 2.4 | 0.5% |
The half-degree square with the most fire-days is centred at 9.75, -84.25 and holds 40% 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.
