As of 2026-10-11 12:00, the 1-hour PM2.5 in Medan is 13 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. The model trend is falling.

Trend (model): falling (-2.2/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 SW（15 km/h）。 The wind is not blowing from the main fire regions, so fresh transport looks less likely.

FAQ all questions

Is it safe to exercise outdoors in Medan right now?

NEA Band 1: continue with normal activities. The current 1-hour PM2.5 is 13 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. Medan is currently at 13. 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.
