Met √Čireann summary:
The first week of October was mostly unsettled with a series of low-pressure systems moving across the country from the southwest bringing bands of rain or showers, interspersed with dry interludes. One such systems, Storm Lorenzo (an ex-hurricane), brought the windiest spell of the month on the 3rd and 4th. The second week continued unsettled with low pressure to the northwest feeding in fur-ther bands of rain of showers, interspersed with some pleasant late autumn sunshine in a strong westerly airflow. The winds slackened towards the end of the second week, where slow moving weather fronts, culminated in widespread heavy and prolonged falls of rain on the 13th and 14th. The mixed theme continued for the second half of the month. Low-pressure systems and their associated weather fronts dominated up to the 19th, and again between the 23rd and 26th. Two dry settled periods between the 20th and 22nd and again between the 27th and 29th, where high pressure moved close to or over the country, bought plenty of late autumn sunshine, and some frost at night in places. The final few days of the month saw weather fronts encroaching from the south with more rain.
