Key Points

To clarify the meteorological conditions on the day of subarachnoid hemorrhage (SAH) onset.
Analyzed meteorological data (pressure, humidity, temperature) for SAH patients from 2014 to 2023.
Assessed the association between SAH onset and various meteorological conditions.
Defined ranges of meteorological conditions into categories based on incidence percentiles.
Identified distinctive meteorological patterns associated with SAH onset days.
Noted significant correlation between decreased net effective temperature and higher SAH incidence.
