As of 2026-10-11 16:00, the 1-hour PM2.5 in Shah Alam is 36 µg/m³ (Normal). Figures are a CAMS atmospheric-model estimate, not an official measurement. This is below the 110 cut-off many youth sports leagues use to call off matches.

Trend (model): steady (-0.6/h) · Note: sport & event organisers often use the 1-hour PM2.5, not the 24-hour PSI.

Why is it hazy?

Wind at ~1.5 km altitude: from the SE（8 km/h）。 That points toward Central Sumatra (Riau/Jambi), South Sumatra, Kalimantan, where fires are active — smoke may be drifting to Shah Alam.

FAQ all questions

Is it safe to exercise outdoors in Shah Alam right now?

NEA Band 1: continue with normal activities. The current 1-hour PM2.5 is 36 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. Shah Alam is currently at 36. 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?

Ventilate normally.
