Today's barometric pressure in Santa Barbara, a 48-hour pressure chart, and a risk score for weather-triggered migraine and headache, based on pressure drops, humidity, and temperature changes.
Loading live forecast for Santa Barbara...
Santa Barbara faces south rather than west, a quirk of the Transverse Ranges that gives the city its own weather. Pressure sits near 1014 hPa with swings of 4 to 7 hPa, and the mountains directly behind town generate a wind pattern found almost nowhere else.
Worst season for migraines: January through March. A narrow storm season from January into March delivers what barometric change the area sees. For the remaining nine months the Santa Ynez range and the offshore island chain hold conditions remarkably level.
Common triggers in Santa Barbara: sundowner wind events off the Santa Ynez range, winter Pacific frontal systems, wildfire smoke during autumn offshore flow. Sundowner winds descend the Santa Ynez range in the late afternoon, sometimes raising temperatures 15 degrees within an hour while humidity collapses. The effect is intensely local, strongest along the foothills and often absent at the waterfront a mile away, which is why two people in the same city can have completely different trigger days.
Typical pressure: Santa Barbara averages 1014 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 1006 hPa. Swings of 4-7 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Santa Barbara is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
