Ireland Weather Forecast: Friday 4 September
Friday's Forecast: A Fresher Start to September
Well, here we are, September 4th, and autumn feels like it's truly making its presence known. If you're heading out this morning, you'll definitely notice a change from the warmth we've been enjoying. Today's Ireland weather forecast brings scattered showers, especially for those in the north and west. So, if you're in Donegal or Galway, keep that umbrella handy.

The good news is not everyone will be dodging raindrops. Parts of the south and southeast look a bit luckier, with some areas potentially staying dry. For places like Wexford or Waterford, you might just get away with leaving the rain gear at home, at least for a while.
As the morning wears on, we should see the clouds breaking up, letting some welcome sunny spells peek through. It's always a bit of a mixed bag, isn't it? One minute you're thinking it's going to be a washout, the next the sun is trying its best to shine. We're definitely in for a cooler and fresher day than we've experienced recently. Highs are expected to range between 15 and 18 degrees Celsius. That's a noticeable drop, so you might want to consider an extra layer, especially if you're planning to be out for any length of time. The breeze will be moderate to fresh and gusty from the west, which will add to that cooler feel.
Tonight: Clearing Up, But Watch for Mist
As Friday evening rolls in, those scattered showers we've seen during the day will start to become isolated. There will be clear spells, giving us a chance to see some stars, or at least a clearer sky. The winds, coming from the southwest to west, will ease up and become light overnight.
However, with lighter winds and clearer skies, we'll need to keep an eye out for patches of mist forming. If you're driving early tomorrow morning, especially in rural areas, visibility might be reduced. Temperatures tonight aren't looking too bad, dropping to between 8 and 13 degrees Celsius. It's cool, but not exactly a deep chill.
The Weekend Ahead: A Shift on Saturday, Rain for Sunday
Looking ahead to Saturday, September 5th, the morning starts off on a relatively dry note with some sunny spells. Much like Friday night, there will be isolated showers and those lingering patches of mist. It's one of those mornings where you might think, "Ah, grand, the weather's holding up."
But don't get too comfortable. Cloud cover is set to increase through the morning, and rain or drizzle will start to develop in the southwest. This band of wet weather is then expected to extend northeastwards, reaching most areas across the country as the day progresses. So, if you have plans for Saturday afternoon, particularly anything outdoors, you might want to make sure you have a backup plan or at least a good waterproof jacket. Along with the rain, we'll see mist and hill fog developing, which could make for some rather atmospheric, if damp, scenery. Highest temperatures for Saturday will be between 15 and 19 degrees Celsius, with light to moderate south to southwest winds shifting to south to southeast.
Sunday, September 6th, looks set to be a breezy day. We're talking fresh and gusty southerly winds, so hold onto your hats! It's going to be mostly cloudy with outbreaks of rain moving eastwards across the country. If you're hoping for a dry Sunday, it seems unlikely. However, there's a silver lining in the temperatures, which are expected to climb a bit, reaching between 18 and 22 degrees Celsius.
Beyond the Weekend: Unsettled Conditions Continue
The general outlook for the coming week, according to Met Éireann, suggests a changeable and often unsettled pattern, with low pressure continuing to be the dominant force. It seems autumn is really settling in with its typical unpredictable nature.
Saturday night will be cloudy and damp initially, with scattered rain or drizzle, mist, and hill fog. It should become drier overnight as the rain becomes isolated. It will feel mild and humid with lowest temperatures of 13 to 16 degrees Celsius, accompanied by a moderate to fresh southerly breeze.
Sunday night will see the rain clearing from the east early on, giving way to mostly dry conditions with clear spells and isolated showers. Winds will ease, becoming light to moderate westerly, and temperatures will drop to between 10 and 14 degrees Celsius.
Monday morning, September 7th, starts dry with sunny spells, but the afternoon will become cloudy, wet, and breezy as another spell of rain moves in from the west. Top temperatures will be between 15 and 18 degrees Celsius, with moderate to fresh and gusty southwesterly winds. Monday night will see that rain clearing eastwards, but there's a chance of another spell of rain moving into southern areas overnight, while mist and fog patches form further north. Lowest temperatures will range between 8 degrees in the north and 14 degrees in the south.
Looking further ahead to Tuesday, September 8th, there's still some uncertainty in the details, but the potential for another spell of wet and breezy weather remains. Highest temperatures on Tuesday could be between 13 and 19 degrees Celsius, with the warmest conditions in the south.
So, while we might have hoped for an Indian summer, it looks like early September is bringing us classic Irish autumn weather. Make sure you're prepared for a bit of everything, and as always, it's a good idea to check the most up-to-date forecast from Met Éireann before you head out. After all, a little bit of planning goes a long way when dealing with our famously fickle climate.
