there was no strong breeze in bangkok on friday night, when it happen. Possibly by the seaside, with an unexpected storm.

No, I don't need sensors, unnecessary cost and I am not obsessed - my cleaners are cheaper than most brand name sensors. I check online (measuring station is in mooban), when I am really bored and also to convince my wife to go on a deserved holiday outside bangkok. Bad air quality in bkk gives a good excuse to escape to seaside.

After 10 years of not caring for air quality I have decided to get purifies because of covid, which can be initiated by lung problems/infection. Purifies run 7/24 on full power, as well as filters on all fans and all mosquito nets.

That's another subject, but without any own PM2.5-meter, you'll never know what's really going on.

So I better  should say: stay well.

Bangkok.   I'm glad the PM2.5 level has decreased,

For your information, and I think, that's all what counts these days,

two screen shots. - By the way, the last days  were unbelievable dirty

up north, and may be, in Isaan too.

Update.  Great numbers for Bangkok today (2 March) - 49 US AQI (green) and 63rd in the world, better than Berlin, Vancouver, Madrid, Johannesburg, Budapest, Vienna, Portland, Brussels, Paris, London....

 

What a great city to live in.

possibly because of the southerly wind for the last few days.

officially from sunday thailand is in hot season - the winter monsoon from north-east (blowing in industrial pollution from china) has changed to southerly, which bring clean air from over the ocean.

Temperature is rising, which might contribute to stronger winds and uplift of pollutants from the ground to higher into atmosphere.

 

I have now only 41 and since the last night switched off purifies and opened all windows and doors, but forecast for evening there would be worsening and from tomorrow morning bad again till saturday. But it's very fluid situation, those forecasts are not reliable at all.

I am not optimistic, as people in phuket experience smog for the last few days. More likely fires in malaysia and indonesia are the reason.

 

ps now, after 20 minutes, jumped to 61. So something wrong might be with bangkok stations

from yesterday morning the majority of my local stations are switched off. The 3 remaining once has been always showing low data. Looks for me as a selection of information. 

District thawi watthana has now only results from satellite data (market with star).

The nearest reliable data in sub-district bang kruai is 17 aqi points higher than those 3 poor ones underscoring

Very good air in Bangkok, almost like in a health resort,

if you compare it with Chiang Mai, Pai, Mae Hong Son.

Cheers Ron.  Vancouver sounds nice; can a 60-year-old Brit with a Lao wife move there easily?  I've never said I'm "living the dream", but also I don't share your doom and gloom and general negativity about life in Thailand.  Anyone would think my kid is the only one living here! Have a nice day.

You are lucky to live in bkk with seasonal air pollution. Here in Esan we have AQI around 200 most of the year. Almost never below 150. Almost every morning Pm 2.5 is 120-170.

Bangkok is a big city and therefore has air pollution just like other big cities, especially in Asia.  It gets worse during the burning season.  It's not too bad today!

I thought it was very good?

By the way, the second screenshot shows Northern Thailand, between Mae Hong Son, Mae Sai/Chiang Rai and Lampang/Phrae.

But thanks for the hint with 'big city' and 'air pollution'.

US AQI is 44 which is still just classed as "good", although that's the average for Bangkok as a whole.  Near me it's currently US AQI 12, which IQAir still class as "good", but I class as "very good"!

Misunderstanding, brewsterbudgen. Sorry.

Tonight (19:00) most parts of Bangkok seem to have very

good air.                            https://aqicn.org/city/bangkok/

The PM2.5 AQI numbers in BKK have been creeping up off and on over the past week, and the normal start of the Thailand smog season is approaching here at the end of Sept. and moving into October.

 

Bangkok today is showing some red area/unhealthy for all PM2.5 readings in a few areas, and a lot of orange area/unhealthy for sensitive group readings in many more areas.

 

Today, I found myself having to turn on my indoor HEPA air purifiers for the first time in months, based on the indoor PM2.5 readings my sensors are showing at home.

Wondering...is that a Xiaomi AQI unit? Did you order that online/ buy it here in Thailand or bring from another location? Do you find it useful/accurate?
