48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Phoenix.
Phoenix's extreme heat and low humidity might seem stable, but monsoon season from June through September brings rapid pressure shifts and dust storms. The 40-degree daily temperature swing between day and night is another common trigger.
Worst season for migraines: July through September. The North American Monsoon transforms Phoenix's weather from bone-dry stability to daily convective storms. Pressure drops during monsoon thunderstorms are brief but sharp, and the humidity spike from single digits to 50-60% creates a dramatic environmental shift for migraine sufferers.
Common triggers in Phoenix: monsoon pressure drops, extreme daily temperature swings of 30-40 degrees, dust storms reducing air quality. Phoenix's desert basin traps heat and creates strong surface low-pressure during summer afternoons. The 40-degree daily temperature swing between predawn lows and afternoon highs is one of the largest of any major US city, creating a daily cycle of atmospheric change that sensitive individuals may notice.
Typical pressure: Phoenix averages 1012 hPa at rest, but storm systems can push readings down to 1000 hPa. Swings of 8-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
