Silver Lake Fire, January 2026 Wakulla

Out · last detection 20 Jan 2026, 19:39 UTC

The fire started on 16 January 2026 in Wakulla, United States, and satellites saw it burning for 5 days. United States agencies (MTBS / NIFC) mapped an official burnt perimeter of 1,949 hectares, spread across a single county.

It is the 40th largest in Florida since 2016 (of 148 with a page). Number 181 in United States in 2026, of 423.

It had gone 12 days without rain (1 mm or more) when it started. Rain came after the fire: 2.7 mm on 24 Jan.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 5 ha in 2016, 16 ha in 2017, 1,714 ha in 2018, 9 ha in 2020, 1,923 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,936 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.2% of the area of London (19 km² against 1,583 km²).

Burnt area inside each county, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

On 22 January 2026 the air beside the fire reached 47 µg/m³ of PM2.5. That day averaged 22: 1.5 times the WHO daily guideline (15).

Frequently asked questions

How long did the Silver Lake Fire last?
The official perimeter only gives the start date (17 January 2026). The end comes from the heat detections inside the perimeter: it burned until 20 January 2026 (5 days from 16 January 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
How much area did it burn?
The official perimeter published by United States agencies (MTBS / NIFC) is 1,949 hectares (19.5 km²). Other tallies, such as daily incident reports, may give slightly different figures.
Which counties burned?
The fire only entered Wakulla (1,944 ha, 1.2 %).
What was the weather like?
During the fire the temperature reached 16.9 °C, humidity dropped to 36 % and gusts hit 55 km/h. The fire danger index (FWI) reached 6, class Low.
Where does this data come from?
From the official burnt perimeter of United States agencies (MTBS / NIFC, public domain), NASA FIRMS VIIRS hotspots and the administrative boundaries of United States. 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: NIFC WFIGS (United States), official.
  • The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 46 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.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

Where this data comes from

The perimeter is official and in the public domain. For past years it comes from MTBS (Monitoring Trends in Burn Severity), run by the U.S. Geological Survey and the USDA Forest Service, which map it on Landsat and Sentinel-2 imagery. For the current and last year it comes from WFIGS at the National Interagency Fire Center (NIFC): incident perimeters mapped by fire crews, aircraft and imagery. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. County boundaries come from geoBoundaries ADM2 (Public Domain). The area per county is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
