Today's air quality in Tripoli — fine particles from traffic and the diesel generators the city runs on, in plain language.
Town Tools builds free, public tools for Tripoli and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.
A plain-language read on the air over Tripoli — the fine-particle (PM2.5) level and how it sits through the day. Air quality is a real health question in a city that runs on private diesel generators, and this gives you the trend at a glance.
Fair Fine for being outside, including exercise, for almost everyone.

With the state grid supplying only a few hours a day, most of Tripoli runs on private neighbourhood generators (the ishtirak). That diesel exhaust is a documented health cost. The most detailed studies are from Beirut — where researchers at the American University of Beirut found that running generators just a few hours a day roughly doubled the carcinogenic particles people breathe, and that diesel was the single biggest source of the city's fine particles — but the same generator economy runs Tripoli. When the grid is off and the neighbourhood is humming on diesel, the exhaust is in the air around you.
Tripoli sits on the coast, and an onshore breeze off the sea clears the air through much of the day. It's on still, windless nights — and when generators run hardest — that fine particles build up closest to the ground, which is often why the early morning feels heaviest before the wind picks up.
Fine-particle pollution is hardest on children, older people, pregnant women, and anyone with asthma or a heart or lung condition. On a high-reading day it helps to keep hard outdoor exercise for a cleaner window, and to keep windows shut on a still evening when a generator nearby is running. Standing right beside a running generator or a busy road is always worse than the area average.
Lebanon has no working public air-quality station in Tripoli — the environment ministry's monitoring network has published nothing since 2018 — so this reading comes from a satellite-fed model of the area, not a sensor on your street. Treat it as a guide to the trend and the bad days, not a precise measurement of the air at your window.
