Southeast Asia — heat, UV & air
The deep tropics — there is no temperate summer here; heat and very high UV run year-round, shaped by the monsoon rather than the calendar. The table below is live: each city’s temperature and feels-like right now, today’s forecast high, the UV index on the WHO scale, and the air on the US EPA scale — every figure sourced and shown with its city’s local clock time.
Reading the table
Now is the air temperature this hour; feels like folds in humidity and wind (in humid heat it runs well above the thermometer; in dry desert heat the two sit closer). Today’s high is the forecast maximum for the calendar day. UVis the WHO UV Index — the strength of skin-damaging ultraviolet reaching the ground; it peaks around local midday, so a low morning value and a “very high” daily max are both normal on the same day. Air is the US EPA Air Quality Index, driven here by fine-particle pollution. Heat figures are measurements, not a health verdict.
