Why is it hazy?

Wind at ~1.5 km altitude: from the E（38 km/h）。 That points toward Kalimantan, where fires are active — smoke may be drifting to Bangkok.

FAQ (all questions)

Is it safe to exercise outdoors in Bangkok right now?

NEA Band 1: continue with normal activities. The current 1-hour PM2.5 is 14 µg/m³.

Will youth training or matches be cancelled because of haze?

That is the organiser's call. Many leagues use a 1-hour PM2.5 above 110 as the cut-off. Bangkok is currently at 14. Below the cutoff. Keep monitoring the 1-hour reading.

Should I check the 1-hour PM2.5 or the 24-hour PSI?

The 24-hour PSI is a slow-moving daily average. For deciding whether to exercise or play now, the 1-hour PM2.5 reflects current conditions better.

What should I do at home?

Ventilate normally.
