Why is it hazy?

Wind at ~1.5 km altitude: from the S（19 km/h）。 That points toward Central Sumatra (Riau/Jambi), South Sumatra, where fires are active — smoke may be drifting to Kuala Lumpur.

FAQ (all questions)

Is it safe to exercise outdoors in Kuala Lumpur right now?
NEA Band 1: continue with normal activities. The current 1-hour PM2.5 is 42 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. Kuala Lumpur is currently at 42. 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.
