Pressure and weather in San Bernardino
Winter Pacific storms provide the clearest seasonal sequence of falling and recovering pressure. Offshore Santa Ana patterns can bring dry winds, and summer heat builds inland; mountain thunderstorms do not necessarily deliver rain to the valley below.
What this means for you
If your day includes a climb toward mountain communities, log the elevation change separately from the local barometric pressure forecast. Heat, windblown dust, and travel can complicate the story when you review a headache after returning to San Bernardino.
