Hill Fire, May 2024 Santa Barbara
The fire started on 28 May 2024 in Santa Barbara, United States, and satellites saw it burning for 2 days. United States agencies (MTBS / NIFC) mapped an official burnt perimeter of 582 hectares, spread across a single county.
It is the 377th largest in California since 2016 (of 442 with a page). Number 301 in United States in 2024, of 371.

Frequently asked questions
- How long did the Hill fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 May 2024 to 29 May 2024 (2 days). The perimeter dates it from 28 May 2024 to 28 May 2024.
- How much area did it burn?
- The official perimeter published by United States agencies (MTBS / NIFC) is 582 hectares (5.8 km²). Other tallies, such as daily incident reports, may give slightly different figures.
- Which counties burned?
- The fire only entered Santa Barbara (585 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 27.6 °C, humidity dropped to 21 % and gusts hit 41 km/h. The fire danger index (FWI) reached 32, class High.
- 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.

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.
