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
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.
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.

FAQ
Is it safe to exercise outdoors in Singapore 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 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.
