Meteorological summer to end dry, sunny and settled - Thurs 26th Aug 2021

High pressure will continue to bring a spell of settled weather to end meteorological summer, with largely dry conditions and long spells of late summer sunshine.

Meteorologist Paul Downes said: “With high pressure firmly in place over Ireland, low pressure systems are being kept well away, maintaining the dry, warm and settled period.”

“Today (Thursday 26th August) will be the warmest day of the week with highs of 21 to 26 degrees. A weakening cold front to the northeast of Ireland will track close to eastern coasts tonight and tomorrow, introducing a slightly cooler east to northeasterly airflow for Friday and the weekend. Temperatures will still be in the high teens to low twenties generally through the weekend with good sunny spells for the most part giving a very pleasant end to the summer.”

Paul continued: “Although it’ll be dry for most this weekend, some cloud may develop along with a spot of drizzle or light shower, especially in northern areas.  It’ll also feel a little cooler on exposed coasts.”

The long spells of late summer sunshine will continue well into next week,  however early next week temperatures will fall closer to normal with highs in the mid to high teens due to a slightly cooler airmass originating in Scandinavia.

How long will the settled spell last?

While a breakdown of the high pressure across Ireland does look to be on the cards later next week, there is still some uncertainty as it very much depends on what is happening in the Equatorial Atlantic.  The global weather connection can clearly be linked as development in the tropical Atlantic region can have knock on effects in the higher latitudes, such as northern Europe.  While there is currently no indication that developing storms may impact Ireland directly next week, the indirect implications can alter our weather patterns, as tropical systems take heat from the warm sea surfaces of the tropics, and release it into the atmosphere. This acts to nudge the flow and alter the speed of the jet stream, which would influence our weather patterns for northern Europe.

Is this an Indian Summer?

An Indian Summer is a term sometimes used to refer to a spell of warm and calm weather in autumn months, usually September to November.  As we are still in meteorological summer, this current spell of weather is simply summer weather, with meteorological autumn starting on September 1.
