Air quality today
What is the air like in Gqeberha and Johannesburg right now?
Johannesburg has cleaner air than Gqeberha right now: AQI 83 (Moderate) against 120 (Unhealthy for sensitive groups). PM2.5 is setting the index in both.
Gqeberha's PM2.5 is about 2.2× the WHO's 24-hour guideline of 15 µg/m³. Johannesburg's PM2.5 is about 1.8× the WHO's 24-hour guideline of 15 µg/m³.
Johannesburg is read from a nearby ground station and Gqeberha is a model estimate, so the two are not quite like for like.

Deforestation · 2001–2025
Which has lost more forest, Gqeberha or Johannesburg?
Gqeberha has lost more: about 2,350 ha of forest within 10 km of its center from 2001 to 2025, against 9 ha around Johannesburg. 198 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: 2017, with 432 ha lost.
Worst year: 2019, with 2 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.

Frequently asked
Gqeberha vs Johannesburg: your questions answered
Is Johannesburg cleaner than Gqeberha?
On air quality, yes, right now: Johannesburg reads AQI 83 against 120, a gap of 37 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. But over the past 6 days, on modeled daily averages, Gqeberha averaged AQI 47 against 70, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Gqeberha and Johannesburg today?
In Gqeberha, at AQI 120: Sensitive groups should limit long or intense outdoor activity. In Johannesburg, at AQI 83: Unusually sensitive people should consider limiting long outdoor exertion.
Which has lost more forest, Gqeberha or Johannesburg?
Gqeberha has lost more: about 2,350 ha of forest within 10 km of its center from 2001 to 2025, against 9 ha around Johannesburg. 198 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Gqeberha or Johannesburg?
Gqeberha has more tree cover: 21.2% of the land within 2 km of its center against 4.2% around Johannesburg, or about 54,547 trees against 13,195. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Gqeberha and Johannesburg need?
Gqeberha needs about 35,507 more to reach its canopy target of 35%, and Johannesburg about 81,053 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Gqeberha and Johannesburg 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. Johannesburg is read from a nearby ground station and Gqeberha is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Gqeberha vs Johannesburg 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 (Mar 11, 2026 and Sep 14, 2026), and the forest figures are published yearly.
