Lamwo fire, 30 December 2022 Lamwo
The fire started on 30 December 2022 in Lamwo, Uganda, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,642 hectares from heat detections, spread across a single municipality.
It is the 433th largest in Northern Region since 2016 (of 1377 with a page). Number 17 in Uganda in 2022, of 63.

This area had burned before
74% of the perimeter overlaps earlier fires recorded since 2016: 348 ha in 2016, 6 ha in 2017, 947 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,212 ha that had burned before.

The smoke
CAMS · CopernicusOn 7 January 2023 the air beside the fire reached 96 µg/m³ of PM2.5. That day averaged 52: 3.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Lamwo fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 30 December 2022 to 8 January 2023 (10 days). The perimeter dates it from 5 January 2023 to 8 January 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,642 hectares (16.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Lamwo (1,653 ha, 0.3 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Uganda (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 5 January 2023 to 8 January 2023. 46 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
