Halloween ‘Indian Summer’ hopes as Met Eireann long-range forecast signals Ireland weather surprise

There are hopes Ireland could see an ‘Indian Summer’ from Halloween and into the start of November.

An Indian Summer is defined as “a period of unusually dry, warm weather occurring in late autumn”.

Met Eireann’s long-range forecast says there is a signal for high pressure from October 31 right through until mid-November.

It says this could mean “more settled conditions in some areas” including “drier than normal conditions” with temperatures “likely to increase a degree above normal”.

The national forecaster issues monthly, long-range forecasts that “can at times provide an insight into weather patterns”.

However it warns that they are “low skill” and subject to change, explaining that “forecasts beyond one week become increasingly uncertain due to the chaotic nature of the atmosphere.”

Giving its long-range prediction for the week of October 31 until November 6, it said: “A possible change to more settled conditions in some areas, with a signal for high pressure to be the main trend over Ireland this week.

“There are signs that a southeast airflow may be dominant this week, which would bring most of the rainfall to southern and eastern coasts. These areas are signalled to have slightly higher than normal precipitation. Most areas elsewhere however are signalled to have drier than normal conditions.

“Temperatures will likely increase, becoming a degree above average for the time of year.”

Looking ahead to the following week, November 7 until November 13, it continued: “High pressure is signalled to dominate over or near Ireland. There is a signal for conditions to be drier than normal across the country. Temperatures are signalled to trend a degree above the seasonal norm.”

The good weather news may come a surprise to some after recent wet and windy weather. And in the meantime, Ireland is set for more unsettled weather this week with frequent spells of rain.

After a windy start to today, it’s due to ease off in the evening and turn cold overnight with temperatures possibly plummeting as low as 0C.

The state meteorological service said: “Mainly dry tonight and turning cold in long clear spells with lowest temperatures of 0C to 5C generally. A touch of grass frost may form in the midlands. Mist and fog patches will also form in light southeast or variable breezes. Milder in parts of the south and southwest with cloudier conditions developing along with freshening winds. Patchy light rain or drizzle will arrive in the southwest towards morning.”

Looking ahead to Tuesday, Met Eireann continued: “Some mist or fog in parts to start, clearing in the morning for a largely dry and sunny day. Cloudier in the southwest with occasional light rain or drizzle. Becoming breezy later, especially in the southwest where southeast winds will increase fresh or strong. Highest temperatures of 12C to 16C.”

Giving its forecast for the rest of the week, it said: “A wet and cloudy day on Wednesday with widespread outbreaks of rain, heaviest and most persistent in the south and southwest with localised flooding possible. Highest temperatures of 11C to 14C generally, reaching up to 15C or 16C in parts of the south and southwest. Easterly winds will be mostly fresh and gusty.

“Becoming largely dry on Thursday with sunny spells as the last of the overnight rain clears the northeast and east. There will be some patchy rain and drizzle, mainly over the southern half of the country. Highest temperatures of 14C to 17C with freshening southeast winds.

“Widespread outbreaks of showery rain on Friday will continue to extend northwards with a clearance to sunny spells moving into the south later in the afternoon. Highest temperatures of 14C to 16C generally.”

The weekend is set to “continue unsettled with highest temperatures remaining in the mid-teens.”
