Air quality today

The air quality in Nakhon Si Thammarat City Municipality is currently classified as Moderate. The primary pollutant identified is PM2.5, the fine particulate matter tracked by the monitoring network. This classification reflects the combined analysis of recent sensor readings. Data are shown via OpenAQ.

Four valid measurements contributed to the assessment. The reference value for PM2.5 is 12.0 µg/m³, and the reference value for PM10 is 25.0 µg/m³. These reference values serve as benchmarks for evaluating particulate concentrations. The information presented is based on the available dataset without additional interpretation. They are provided for public awareness. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Nakhon Si Thammarat City Municipality 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). All values come from a single monitoring location, the Elderly Health Rehabilitation Center, and the file holds six rows of data, one for each pollutant. The station count is therefore one, meaning the figures represent conditions at that specific site rather than a city‑wide network.

Freshness of the data varies by pollutant. CO (0.2 ppm), NO₂ (0.007 ppm), PM₁₀ (25.0 µg/m³) and PM₂.₅ (12.0 µg/m³) were last updated in early February 2026, placing them within the most recent 30‑day window. In contrast, O₃ (0.003 ppm) was recorded on 2025‑04‑20 and SO₂ (0.0 ppm) on 2024‑09‑20, which are classified as older entries. Overall, four of the six rows fall into the “updated within 30 days” category, while the remaining two are older, and none are from today, the last three days, or the last seven days.

Because each pollutant has a single recorded value, the statistical spread is zero – the minimum, median and maximum are identical for every metric. This lack of variability means the dataset does not capture fluctuations over time or across different parts of the city. Users should keep in mind that conditions can differ by location and moment, and the current snapshot reflects only the measurements taken at the Elderly Health Rehabilitation Center at the dates listed.
