Deforestation · 2001–2025
Which has lost more forest, Kingston or Montego Bay?
Montego Bay has lost more: about 1,890 ha of forest within 10 km of its center from 2001 to 2025, against 466 ha around Kingston. 1,530 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2016, with 54 ha lost.
Worst year: 2025, with 624 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Kingston vs Montego Bay: your questions answered
Is Montego Bay cleaner than Kingston?
On air quality, yes, right now: Montego Bay reads AQI 42 against 52, a gap of 10 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 7 days, on modeled daily averages, Montego Bay averaged AQI 34 against 42, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Kingston and Montego Bay today?
In Kingston, at AQI 52: Unusually sensitive people should consider limiting long outdoor exertion. In Montego Bay, at AQI 42: Air quality is satisfactory for everyone.
Which has lost more forest, Kingston or Montego Bay?
Montego Bay has lost more: about 1,890 ha of forest within 10 km of its center from 2001 to 2025, against 466 ha around Kingston. 1,530 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Kingston or Montego Bay?
Montego Bay has more tree cover: 44.0% of the land within 2 km of its center against 14.5% around Kingston, or about 114,455 trees against 45,553. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Kingston and Montego Bay need?
Kingston needs about 48,695 more to reach its canopy target of 30%, and Montego Bay about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Kingston and Montego Bay measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings are model estimates, with no ground station close enough to either. Nothing is adjusted for population, city limits or climate.
How often does the Kingston vs Montego Bay comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 15, 2026 and Sep 13, 2026), and the forest figures are published yearly.
