Pressure and weather in Upland
Winter Pacific troughs change Upland’s regional pressure pattern, while cool-season Santa Ana episodes can send dry offshore winds through the foothills. Summer ridges favor inland heat, with conditions on mountain trails differing substantially from those along Foothill Boulevard.
What this means for you
A climb toward San Antonio Canyon changes elevation as well as exposure to sun and wind. Keep that trip separate from the city’s forecast readings when using a migraine tracker app to examine a possible weather association.
