A WELCOME blast of warm air from the Mediterranean gave us one of the warmest Octobers in recent memory, according to the latest monthly weather summary from Met Eireann.

Warm air pushing up from the continent led to all mean temperatures being the highest in six years and in some cases 12 years.

However a blast of Arctic air later in the month scuppered what was shaping up to be one of the warmest Octobers on record, according to Met Eireann meteorologist Ruth Coughlin.

The midlands enjoyed the warmest overall temperatures with the Met Eireann weather stations at Oak Park in Co Carlow and Mullingar, Co Westmeath registering just under two degrees above their mean temperatures of 12.1C and 11.4C respectively.

Mullingar recorded its warmest October in 12 years followed by Oak Park at six years.

Elsewhere, temperatures on average were their warmest in six to 12 years while some stations along the east and Atlantic coasts had their highest temperatures in 42 years.

Mount Dillon in Co Roscommon was the national hotspot, recording a balmy 21.1C on October 2 while Furnace in Newport, Co Mayo lived up to its name, smashing a 53-year record with temperatures of 20.9C on the same day.

Yet despite the warm temperatures, rainfall was above average except in parts of the north, west and northwest.

While both Oak Park and Mullingar enjoyed warm temperatures, they also had lots of rain with Mullingar recording its wettest October in 63 years and Oak Park having its wettest October since 2008.

Weather stations in the south, southeast and southwest all had their wettest Octobers in five to eleven years.

Johnstown Castle in Co Wexford recorded the wettest day of the month when 40.1mm of rain fell on October 18.

Despite the showers, there was also plenty of sunshine with most stations reporting average to above average hours of sunshine with Cork Airport recording the sunniest day of the month on October 10 with 9.9 hours of sunshine.

But a system of low pressure moving in from the Atlantic last weekend brought a band of thundery downpours to mostly south Munster and south Leinster for the remainder of the month along with strong winds.

Mace Head weather station in Co Galway recorded the highest winds of the month with gusts of 111 km/h on October 27.
