Wind is the other half. Met Éireann gives the prevailing wind as between south and west. In Storm Éowyn on 24 January 2025, Valentia recorded a gust of 137 km/h and Kerry was under a Status Red wind warning from 3am to 10am. Kerry was also among the counties under red warnings for Storm Ophelia in October 2017.
Rain falls hardest on the mountains. Met Éireann notes that in many mountainous districts rainfall exceeds 2,000 mm a year, against 750 to 1,000 mm over most of the east, and the record-holding stations above are mostly mountain stations. Lower ground gets less, but a sunken trampoline anywhere in the county needs its drainage checked first.
