Air quality today
The air quality in Hua Hin is currently classified as Moderate. The primary pollutant measured is PM2.5 (fine particles). Recent observations show a PM2.5 concentration of 31.0 µg/m³ and a PM10 level of 78.0 µg/m³, based on six valid measurements collected through OpenAQ.
These values reflect the present state of ambient air in the city without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Hua Hin currently draws from a single monitoring location – the Hua Hin Weather Station Prachuap Khiri Khan Meteorological Station – and provides one recent record for each of the six common air‑quality pollutants tracked by OpenAQ: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All six measurements were last updated on 2026‑02‑10 at 22:00 UTC, so the freshest data for the city is less than a week old.
Because there is only one row per pollutant, the reported values show no internal variation: each metric has identical minimum, median and maximum figures. CO registers at 0.5 ppm, NO₂ at 0.024 ppm, O₃ at 0.033 ppm, PM₁₀ at 78 µg/m³, PM₂.₅ at 31 µg/m³ and SO₂ is recorded as 0.0 ppm. The lack of spread means the dataset cannot illustrate day‑to‑day fluctuations or spatial differences across Hua Hin; it simply reflects a single snapshot from one site.
Overall, the coverage is limited to this lone station, so while the data are recent, they represent only one point in the city’s atmosphere at a specific time. Users should keep in mind that air quality can differ by neighborhood and over shorter intervals than the timestamp captures, and additional monitoring locations would be needed to portray a fuller picture of conditions throughout Hua Hin.

Data notes
The data shown reflects six valid measurements and is Updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. These values provide a snapshot of current conditions in Hua Hin, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured by this summary.
