Pressure and weather in San Cristobal de Las Casas
Summer rains and moisture interacting with the highlands bring frequent cloud and showers. Winter cold-air surges can reinforce cool, damp conditions, while the drier season also allows clearer nights and substantial day-to-night temperature differences.
What this means for you
If you travel between San Cristóbal and lower Chiapas towns, record the altitude change as well as symptoms. A migraine tracker app can organize the comparison, but lower raw pressure at the highland destination is not proof of a weather-triggered attack.
