48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Saint Paul.
Saint Paul sits on the Mississippi bluffs across the river from Minneapolis, at 242 metres. Pressure averages 987 hPa with swings reaching 14 hPa, and the river valley gives the city a slightly different local pattern from its twin.
Worst season for migraines: December, February and March. December stands out as the most volatile month here, earlier than in most of the country, driven by the first sustained Arctic intrusions of the season meeting residual autumn moisture. The pattern continues through February with steadily colder air.
Common triggers in Saint Paul: Mississippi valley cold air inversion, early season Arctic intrusions, clipper and Gulf system alternation. Cold air settles into the deep Mississippi valley on calm winter nights while the bluff tops stay warmer, and temperature differences of several degrees across the city are routine. The Twin Cities also sit at the boundary where Alberta Clippers and Gulf-fed systems both reach, giving two distinct storm types through a single season.
Typical pressure: Saint Paul averages 987 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 970 hPa. Swings of 7-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Saint Paul weather trigger migraines?
Yes. Saint Paul experiences 7-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Mississippi valley cold air inversion, early season Arctic intrusions, clipper and Gulf system alternation.
What time of year are migraines worst in Saint Paul?
