Pressure and weather in Oaxaca
Summer rain develops as moist air and tropical disturbances interact with the surrounding high terrain. Winter is usually drier, though cold-air outbreaks farther north can reshape regional winds and bring cooler conditions into parts of the valleys.
What this means for you
For weather migraine tracking in Oaxaca, distinguish a valley afternoon from a journey into the Sierra. Record where symptoms occurred instead of matching every mountain outing to a pressure reading from the city center.
