Air quality today
What is the air like in Abuja and Lagos right now?
Lagos has cleaner air than Abuja right now: AQI 88 (Moderate) against 91 (Moderate). PM2.5 is setting the index in both.
Abuja's PM2.5 is about 2.0× the WHO's 24-hour guideline of 15 µg/m³. Lagos's PM2.5 is about 1.9× the WHO's 24-hour guideline of 15 µg/m³.
Both readings come from nearby ground stations.

What it means today
Is it safe to go outside in Abuja and Lagos today?
Unusually sensitive people should consider limiting long outdoor exertion. Both are in the same EPA band today (Moderate), so the advice is the same.
Exercise outdoors
Fine for most people; unusually sensitive people should take long or hard exercise easier.
Windows
Fine to open; close them if you are sensitive to pollution.
Masks
Not needed for most people.
Air purifier
Worth running if you are sensitive.

Deforestation · 2001–2025
Which has lost more forest, Abuja or Lagos?
Abuja has lost more: about 93 ha of forest within 10 km of its center from 2001 to 2025, against 31 ha around Lagos. 93 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 11 ha lost.
Worst year: 2004, with 4 ha lost.

Trees
Which has more trees, Abuja or Lagos?
Abuja has more tree cover: 26.5% of the land within 2 km of its center against 0.3% around Lagos, or about 83,252 trees against 541.
The dark mark is each place's canopy target: 30% of the land, raised where air quality is poor.

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
Abuja vs Lagos: your questions answered
Is Lagos cleaner than Abuja?
On air quality, yes, right now: Lagos reads AQI 88 against 91, a gap of 3 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, Lagos averaged AQI 66 against 130, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Abuja and Lagos today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Abuja reads AQI 91 and Lagos reads AQI 88.
Which has lost more forest, Abuja or Lagos?
Abuja has lost more: about 93 ha of forest within 10 km of its center from 2001 to 2025, against 31 ha around Lagos. 93 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Abuja or Lagos?
Abuja has more tree cover: 26.5% of the land within 2 km of its center against 0.3% around Lagos, or about 83,252 trees against 541. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Abuja and Lagos need?
Abuja needs about 10,996 more to reach its canopy target of 30%, and Lagos about 53,557 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Abuja and Lagos 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 come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Abuja vs Lagos 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 (Oct 30, 2026 and Jan 24, 2026), and the forest figures are published yearly.
