Air quality today
What is the air like in Naivasha and Nakuru right now?
Naivasha has cleaner air than Nakuru right now: AQI 71 (Moderate) against 76 (Moderate). PM2.5 is setting the index in both.
Naivasha's PM2.5 is about 1.6× the WHO's 24-hour guideline of 15 µg/m³. Nakuru's PM2.5 is about 1.1× the WHO's 24-hour guideline of 15 µg/m³.
Both readings are model estimates, with no ground station close enough to either.

Deforestation · 2001–2025
Which has lost more forest, Naivasha or Nakuru?
Naivasha has lost more: about 521 ha of forest within 10 km of its center from 2001 to 2025, against 99 ha around Nakuru. 319 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: 2022, with 80 ha lost.
Worst year: 2015, with 19 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
Naivasha vs Nakuru: your questions answered
Is Naivasha cleaner than Nakuru?
On air quality, yes, right now: Naivasha reads AQI 71 against 76, a gap of 5 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 6 days, on modeled daily averages, Naivasha averaged AQI 39 against 45, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Naivasha and Nakuru today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Naivasha reads AQI 71 and Nakuru reads AQI 76.
Which has lost more forest, Naivasha or Nakuru?
Naivasha has lost more: about 521 ha of forest within 10 km of its center from 2001 to 2025, against 99 ha around Nakuru. 319 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Naivasha or Nakuru?
Naivasha has more tree cover: 21.8% of the land within 2 km of its center against 14.6% around Nakuru, or about 67,254 trees against 43,620. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Naivasha and Nakuru need?
Naivasha needs about 25,297 more to reach its canopy target of 30%, and Nakuru about 46,010 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Naivasha and Nakuru 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 Naivasha vs Nakuru 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 24, 2026 and Sep 7, 2026), and the forest figures are published yearly.
