US South & Gulf Coast — heat, UV & air
Heat plus humidity — the feels-like temperature runs well past the thermometer from Texas to Florida, and Saharan dust or wildfire smoke can colour the air-quality picture. 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.
