Why is it hazy?

Wind at ~1.5 km altitude: from the SE（12 km/h）。 That points toward South Sumatra, Kalimantan, where fires are active — smoke may be drifting to Muar.

FAQ all questions

Is it safe to exercise outdoors in Muar right now?

NEA Band 2: reduce strenuous outdoor activity for the next hour — go easy and short, or move indoors. Stop if you cough or feel chest tightness. The current 1-hour PM2.5 is 57 µg/m³.

Read the full answer →
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. Muar is currently at 57. Below the cutoff. Keep monitoring the 1-hour reading.

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.
