Bachok fire, 10 April 2026 Bachok

Out · last detection 16 Apr 2026, 18:28 UTC

The fire started on 10 April 2026 in Bachok, Malaysia, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 536 hectares from heat detections, spread across a single municipality.

It is the 10th largest in Kelantan since 2016 (of 13 with a page). Number 31 in Malaysia in 2026, of 37.

The power measured by the satellite is low (20.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 16 Apr.

This area had burned before

51% of the perimeter overlaps earlier fires recorded since 2016: 771 ha in 2016, 58 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 273 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Bachok fire last?
GWIS (Copernicus) dates it between 10 April 2026 and 15 April 2026: 6 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 536 hectares (5.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Bachok (540 ha, 1.9 %).
What was the weather like?
During the fire the temperature reached 36.0 °C, humidity dropped to 45 % and gusts hit 35 km/h. The fire danger index (FWI) reached 16, class Moderate.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Malaysia (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.

Emergency number: 999

Satellite cross-check

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.

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 (Creative Commons Attribution 3.0 License). 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.
