Why is it hazy?

Wind at ~1.5 km altitude: from the S（13 km/h）。 That points toward Central Sumatra (Riau/Jambi), South Sumatra, where fires are active — smoke may be drifting to Singapore.

What to do

Team sport / training
Below the cutoff. Keep monitoring the 1-hour reading.
Running / cycling
Go easy and short, or move indoors. Stop if you cough or feel chest tightness.
School PE / recess
Light activity only, shorten outdoor time, indoor alternatives for asthmatic kids.
Commute / errands
No special precautions.
Windows & home air
Keep windows closed; run an air purifier (HEPA) or A/C on recirculate. Avoid frying/incense/candles indoors.
Hang laundry outside
OK to dry outside.
Outdoor dining / events
Prefer indoor/covered venues; keep it short.
Pets
Shorten walks; avoid intense play outdoors.

FAQ

Is it safe to exercise outdoors in Singapore right now?
Go easy and short, or move indoors. Stop if you cough or feel chest tightness. The current 1-hour PM2.5 is 93 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. Singapore is currently at 93. 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?
Keep windows closed; run an air purifier (HEPA) or A/C on recirculate. Avoid frying/incense/candles indoors.
