Newcastle fire, 10 August 2024 Newcastle

Out · last detection 14 Aug 2024, 11:15 UTC

The fire started on 10 August 2024 in Newcastle, South Africa, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,932 hectares from heat detections, spread across a single municipality.

It is the 74th largest in KwaZulu-Natal since 2016 (of 171 with a page). Number 72 in South Africa in 2024, of 121.

The weather it burned in

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

86% of the perimeter overlaps earlier fires recorded since 2016: 4 ha in 2017, 1,467 ha in 2018, 1,441 ha in 2020, 1,330 ha in 2021, 22 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 2,518 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.9% of the area of London (29 km² against 1,583 km²).

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.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Newcastle fire last?
GWIS (Copernicus) dates it between 10 August 2024 and 14 August 2024: 5 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 2,932 hectares (29.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Newcastle (2,949 ha, 1.6 %).
What was the weather like?
During the fire the temperature reached 25.9 °C, humidity dropped to 7 % and gusts hit 64 km/h. The fire danger index (FWI) reached 60, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of South Africa (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 from the perimeter: the VIIRS detections inside it did not change them. 177 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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 ADM3 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
