Thread: Pattaya Air Suffers ‘Worst’ PM2.5 Hazardous Dust Level

Pattaya holds the top spot for the highest PM2.5 health-hazardous dust level as of November 5th, 2023.


The concentration of extra-small particles has surged to 154 micrograms per cubic meter in Pattaya, far above the safety threshold of 50 micrograms per cubic meter, according to the IQAir website on November 5th, 2023.

AQI (Air Quality Index) levels surpassing 100 fall into the “unhealthy” (red) category, while those exceeding 200 are classified as “very unhealthy” (purple). Beyond 300, they are deemed “hazardous.”

The province in Thailand with the highest levels of pollution was Samut Sakhon province. Additionally, areas in Bangkok, Nonthaburi, and Samut Prakan were also noted for elevated levels.


Meanwhile, Thailand ranks 25th globally for air quality, with an average AQI of 75, indicating PM2.5 levels exceeding international standards.


The top 10 cities with the worst air in Thailand as of November 5th, 2023, are as follows:


Pattaya, Chonburi – AQI 154
Bang Kruai District, Nonthaburi – AQI 120
Banglamung District, Chonburi – AQI 120
Mueang Nakhon Ratchasima District, Nakhon Ratchasima – AQI 118
Mueang Udon Thani District, Udon Thani – AQI 116
Mueang Nonthaburi District, Nonthaburi – AQI 105
Thawi Watthana District, Bangkok – AQI 105
Bang Khun Thian District, Bangkok – AQI 102
Bang Na District, Bangkok – AQI 99
Mae Sot District, Tak – AQI 97

Relevant officials and agencies have not issued an official explanation as of press time for what they believe is the cause of the poor air quality in the Pattaya and Banglamung area over this past weekend but rainstorms expected over the next week are believed to bring at least some relief.

Pattaya Air Suffers 'Worst' PM2.5 Hazardous Dust Level - The Pattaya News

Today’s US AQI reading for Pattaya is, as I write now, 37.

As already explained to the Septic Twat, most Pattaya pollution is dependent on plumes from Bangkok and environs, and from Maptaput./ Rayong.

Variations are inevitable but here we are affected by the monsoons and at present we are transitioning to a NNE airflow which brings cooler zephyrs but also a lot of shit from the industrial plants between greater Bkk, Chachaongsao, Chonburi etc.

But better than Bkk for most of the year, obvs.

It was bonfire night yesterday....
