Air quality today

The air quality in Hat Yai today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 11.7 µg/m³, based on one valid observation.

This assessment reflects the current monitoring snapshot for the city. No additional pollutants are reported, and the dataset includes only a single measurement point. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Hat Yai contains measurements for six pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). These values come from seven recorded rows that originate at two monitoring stations within the city.

The most recent observation is for PM2.5, reported at 11.7 µg/m³ by the Hat Yai Municipality station on 2026‑02‑10 10:00 UTC; this also has the widest spread, with a minimum of 7.6 µg/m³, a median of about 9.65 µg/m³ and a maximum of 11.7 µg/m³ across the rows. All other pollutants are based on older entries: CO (0.1 ppm) was last logged on 2023‑08‑03 02:00 UTC, NO₂ (0.006 ppm) on 2025‑05‑25 15:00 UTC, O₃ (0.009 ppm) on 2025‑06‑30 15:00 UTC, PM10 (41.0 µg/m³) on 2023‑04‑29 00:00 UTC and SO₂ (0.113 ppm) on 2022‑11‑15 00:00 UTC. Each of these older measurements shows a single recorded value with no variation across the rows.

Overall, the data set is unevenly refreshed: only PM2.5 provides a measurement from the past week, while the remaining five pollutants rely on records that are months to years old. The limited number of stations (two) and the small row count (seven) mean that spatial coverage within Hat Yai is modest, and temporal gaps are large for most contaminants. Consequently, the available figures represent snapshots rather than continuous monitoring, and actual conditions in different parts of the city may differ from these isolated readings.

Data notes

The data for Hat Yai is based on a single valid measurement and was refreshed recently, Updated within 3 days (last update: 2026‑02‑10T10:00:00+00:00). This snapshot reflects conditions at the time of that reading; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single data point.
