This summer was the warmest on the island of Ireland since records began in 1900.
The average summer temperature this year was 16.19C, which is 0.08C higher than the previous hottest summer of 1995.
This year was also the hottest spring on record and is on course to push out 2023 and claim the crown as the hottest year on record.
Met Éireann climatologist Paul Moore has said that the increasing trend in temperatures is clear to see.
"The added heat in the system now and the continuous background warming is pushing up the mean temperatures and the minimum temperatures and can now transform an unexceptional season into a record-breaking one", he said.
However, he added that the temperature increases are due to climate change, and the baseline has gone up.
He added: "We're already living in a changed climate. We've already warmed by over 1.1C so that continuous warming due to human-induced climate change is now coming into our figures and in a more obvious way, where the baseline has gone up so much now that, as we've seen the record-breaking warm spring, a record-breaking warm summer now."
He said that the nighttime temperatures are rising quicker than daytime temperatures, which is due to several reasons, including marine heatwaves and that pushes up the mean temperature.

Mr Moore said that each season is going to get warmer and spring and summer will get drier, and when conditions are right, it will mean more rain as well due to climate change.
He said that the springs are not necessarily wetter, but warmer, and each season is getting warmer.
"Spring and summer will gradually become drier", he said, "so with this increasing temperature, there's more evaporation, so there's more moisture in the atmosphere.
"So, when the conditions are right, we've low pressure dominating, then more rain can fall, and so we can get more rainfall and intense rainfall events because there's more moisture in the atmosphere.
"But when we're dominated by high pressure, we'll have more dry spells. We'll have more droughts and heat waves in the summer as well."
For farmers, he said it is very unsure what is going to happen as often in spring the ground is so sodden that it cannot be worked, and conversely it can be too dry in other years.
"Even though the growing season has increased both at the beginning and at the end, it's very unsure what's going to happen. We saw a couple of years ago the ground in March, April was too soft, and there was too much water in it, so they couldn't get out to work the land, and that was kind of a big issue back then.
"And then a couple of years before that, it was so dry that the growth was late starting, and it didn't grow as much because it was so dry", he explained.
