What could change it

The region: fires, smoke and wind

Red dots: fires seen by NASA satellites in the last 24 hours. Blue arrows: model wind; dashed purple arrows: where smoke from the main fire areas may drift in 12 hours; dark arrows: measured at airports. Pick a time to update the winds.

What the agencies say

Rain

Showers wash smoke out, but only for a while.

Rain so far, and the next hours

Rain model by place (mm/h)

Model grid is about 10 km, so nearby places can look alike. Showers are hit-and-miss, so use this as a guide only.

Projection. Rolls each region's 24-hour PM2.5 average forward from the latest reading, assuming the hourly PM2.5 holds at its latest value and the hours leaving the window matched the reading 21 hours before the latest one, then converts to PSI. It is an estimate, not an NEA forecast. New smoke, a wind shift or rain changes it, and smoke aloft mixing down on a hot afternoon can push readings up faster than it shows.

Map. NEA only measures five regions, so each of the 47 forecast-area dots takes the value of its nearest region centre.

Wind. Regional arrows are model winds near the ground; smoke often travels a few hundred metres up, where the wind can differ. Singapore's own station winds are light and patchy, so the page shows only their typical speed; each station is in the table above. Fire areas are read off ASMC's regional map, placed at a named town nearby.

Rain. Gauge counts are spot samples of NEA's 5-minute rainfall, not a continuous record. The rain model is the Norwegian Meteorological Institute's (met.no) forecast, a second opinion beside NEA; its overnight "fog" symbol is likely haze.
