Mercury to hit 28 degrees
A ridge of high pressure to the south west over the Azores is set to have Cavan sizzling towards the end of the week.
While cloudy and possibly drizzly conditions are expected today (Wednesday) and possibly tomorrow, temperatures are expected to be in the early twenties.
Come Thursday, Cavan’s temperatures are expected to hit twenty-three degrees with “more widespread” and “prolonged” sunshine expected on Friday, according to Met Éireann Meteorologist Liz Walsh.
Speaking to the Celt, she said high pressure will become more centred over our area towards the end of the week.
“What that does is, because the winds go clockwise around high pressure, you get a south easterly air flow and you get an influx of warmer air coming up off the nearby continent,” she explained, adding that this air is coming from the direction of Netherlands, Belgium and northern France.
“That basically results in a rise in temperatures,” Ms Walsh explained.
On Friday temperatures are expected to hit 25 degrees in Cavan, while Saturday looks like the “peak” of the hot weather.
“I’m seeing current indications of 26-28 degrees for Cavan so we could hit thirty degrees somewhere in the country that day.”
On Sunday, temperatures could again hit the 26-27 degree mark in the Breffni county.
It’s not going to be heat wave territory for Cavan, however. For the weather to be classed as a heatwave, there must be temperatures of over 25 degrees recorded for five consecutive days.
“At this stage it doesn’t look like that is going to happen in a widespread countrywide sense,” said Ms Walsh, adding that it “may happen” at some locations.
“For Cavan it kind of looks like it’s a three-day wave.”
However, the meteorologist warned that there is going to be an influx of cool air, which could result in a “thundery breakdown” later in the weekend. “There’s a cold front coming in off the Atlantic,” she said, predicting that this will show its effect on Sunday night or early on Monday morning, with “a change flooding in from the west” bringing cooler temperatures.
There is still “uncertainty” on when this will take effect, however temperatures on Monday are expected to be between 18 and 20 degrees, which is “average for the time of year”.
Those in the Breffni county can expect temperatures to begin to ramp up Thursday, while Friday and the weekend will experience the higher temperatures.
“Warm nights are likely to occur with the warmer weather, which could make for some uncomfortable sleeping especially this weekend, and as always with warm and sunny weather in the forecast, people should exercise caution around waterways and think water safety. UV levels will be high so be sun smart, seek shade, wear a hat and apply sun screen,” Ms Walsh advised.
Asked if these temperatures are normal for this time of year, Ms Walsh responded “it’s July and it’s summer so yes.”
She added: “We have had bad summers, we have good summers.. on average I’d say it’s probably a good summer by Irish standards.”
“We’re getting some hot temperatures so I would say just enjoy it.”
Meawhile, the latest Met Éireann Climate Statement for June 2025 showed that, despite a cool start, June 2025 was the fourth warmest on record for Ireland, with all stations recording mean temperatures above their Long Term Average.
The highest temperatures recorded so far this year was 29.6 degrees Celsius, which was reported at Mount Dillon in Roscommon. The month’s lowest air temperature of 3.5 °C was reported at both Mount Dillon on June 2 and Mullingar, Co Westmeath, on June 8. Meanwhile rainfall was above average in most places; and sunshine was below average last month.
