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. Hanoi is currently at 106. Within 15% of the cutoff (110). Could flip within the hour — check again before leaving.

Read the full answer →
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.

Read the full answer →
What should I do at home?

Keep windows closed; run an air purifier (HEPA) or A/C on recirculate. Avoid frying/incense/candles indoors.
