Pressure and weather in Pasadena

Pacific winter storms bring rain to Pasadena and colder weather at mountain elevations. Offshore wind episodes can dry the foothills, while summer valley heat often differs from conditions at coastal Los Angeles; local terrain affects wind exposure.

What this means for you

If an outing starts in Pasadena and climbs toward the mountains, write down altitude and activity as well as pressure. Review heat and fire-weather information before relying on a migraine tracker app diary to interpret discomfort after a hike.
