Ireland's rare September calm — weeks of settled skies and mild air — is drawing to a close, as competing weather models signal a return to the Atlantic's familiar authority by mid-week. The shift arrives with particular weight this year, coinciding with the National Ploughing Championships, one of the country's great communal gatherings, where the difference between a forecast and a downpour is the difference between celebration and mud. In the space between two disagreeing models, an entire nation finds itself doing what it has always done: watching the sky and hoping.
Ireland's dry spell to break with heavy rain Thursday as Ploughing Championships loom
Let's hope GFS is right for the Ploughing Championships
Mark
Why does the timing of this rain matter so much? It's just weather.
Mimi
The National Ploughing Championships draws massive crowds—thousands of people working outdoors in the fields. Heavy rain doesn't just make it uncomfortable; it turns the ground to mud, makes machinery harder to operate, and can genuinely disrupt the event. It's not abstract weather; it's the difference between a successful gathering and a muddy, difficult one.
Mark
So these two weather models—GFS and ECWMF—they're giving completely different answers?
Mimi
Not completely different, but meaningfully so. Both agree on dry conditions through the weekend. But one says the championships stay mostly dry, and the other says rain arrives mid-week and gets heavy by Thursday. That's the difference between hoping and bracing.
Mark
What does Alan O'Reilly actually think will happen?
Mimi
He's hedging, which is what forecasters do when the models disagree. But his phrasing—"Let's hope GFS is right"—tells you which outcome he's rooting for. He's not confident enough to predict it outright.
Mark
Is this unusual for September in Ireland?
Mimi
The dry spell itself has been unusual—that's why it's newsworthy. September is typically wetter. So the fact that it's been dry enough to comment on, and now it's about to break, makes this a genuine shift in the pattern.
Mark
What happens after Thursday?
Mimi
The rain doesn't stop. Met Eireann is saying there will be bands of rain and showers moving through from midweek onward, with only brief dry spells between them. September's dry run is over.
El Pulso
- Ireland's unusually dry September is on borrowed time, with heavy rain forecast to arrive by Thursday in what meteorologists describe as a decisive pattern shift.
- The stakes are sharpened by the National Ploughing Championships beginning Tuesday — one of Ireland's largest annual events, drawing thousands into open fields for days.
- Two weather models are telling contradictory stories: the GFS offers hope of dry conditions through the event, while the ECWMF warns of showers mid-week building to heavy rain by Thursday.
- For now, pleasant conditions hold — crisp mornings, mild afternoons of 14–17°C, and bright spells — but the Atlantic is already massing to the west.
- By Tuesday, patchy rain and drizzle are expected to push eastward, and from midweek onward Met Éireann says the settled spell will be firmly behind Ireland.
Ireland's rare September calm — weeks of settled skies and mild air — is drawing to a close, as competing weather models signal a return to the Atlantic's familiar authority by mid-week. The shift arrives with particular weight this year, coinciding with the National Ploughing Championships, one of the country's great communal gatherings, where the difference between a forecast and a downpour is the difference between celebration and mud. In the space between two disagreeing models, an entire nation finds itself doing what it has always done: watching the sky and hoping.
Ireland has been living on borrowed sunshine this September, but forecasters are now warning that a significant weather shift is imminent — heavy rain expected to sweep the country by next Thursday, ending weeks of unusually settled conditions.
The timing is particularly loaded. The National Ploughing Championships begin this Tuesday, drawing large crowds into the fields for days. Carlow Weather forecaster Alan O'Reilly is watching two competing models with close attention: the GFS suggests the country stays largely dry through the event, while the ECWMF paints a grimmer picture of scattered showers Tuesday and Wednesday, followed by heavy rain by Thursday. "Let's hope GFS is right for the National Ploughing Championships," O'Reilly said — a sentiment many across Ireland will share.
For now, conditions remain agreeable. Friday will bring bright spells and variable cloud, with temperatures reaching 14 to 17 degrees Celsius. The weekend continues the dry trend — Saturday mostly clear after morning mist, Sunday seeing some light rain or drizzle in the north while the south stays drier. Monday is forecast mild and largely dry, with freshening southwesterly winds hinting at what's to come.
By Tuesday the Atlantic begins to assert itself, with patchy rain moving in from the west. From midweek onward, Met Éireann says further bands of rain and showers will cross the country. The settled September that Ireland has enjoyed will, by week's end, be a memory — and whether the Ploughing Championships escape the worst of it remains, for now, an open question between two disagreeing forecasts.
Ireland has enjoyed an unusually dry September, but that reprieve is about to end. Next Thursday, forecasters are warning of a significant shift in the weather pattern—heavy rain is expected to sweep across the country in what meteorologists are calling a dramatic swing from the settled conditions that have prevailed for weeks.
The timing could hardly be more awkward. Hundreds of people are hoping the dry weather holds through this coming Tuesday, when the National Ploughing Championships begin. It's one of Ireland's largest annual gatherings, drawing crowds who will be out in the fields for days. Alan O'Reilly, a forecaster with Carlow Weather, is watching two competing weather models closely. One—the GFS model—suggests most of the country will stay largely dry through the event. The other, the ECWMF model, paints a grimmer picture: scattered showers on Tuesday and Wednesday, followed by heavy rain by Thursday. "Let's hope GFS is right for the National Ploughing Championships," O'Reilly said, the hope in his words reflecting what many Irish people are thinking.
For now, conditions remain pleasant. This morning brought a crisp start, with temperatures dipping to around 5.6 degrees Celsius at O'Reilly's weather station, but the day itself is shaping up mild with patches of early sunshine breaking through light fog. Most of the country will see a bright morning, though the north is expecting scattered showers. Through the rest of Friday, variable cloud and sunny spells should dominate, with temperatures climbing to between 14 and 17 degrees Celsius in a moderate northerly breeze. Ulster may see a few light showers lingering into the afternoon and evening, but elsewhere the day should be largely pleasant.
The weekend looks set to continue the dry trend. Saturday will dawn with mist and fog patches that should gradually clear, leaving a mostly dry day with bright intervals and some cloud cover. Overnight temperatures will dip to between 3 and 7 degrees, with mist and fog forming under light winds. Saturday night will remain dry across most areas, though clouds will begin thickening from the north, bringing patchy rain or drizzle to northern counties as the night progresses. Sunday morning will see that light rain or drizzle persist briefly over the northern half of the country, but the south should stay drier with some sunny spells developing. Temperatures on Sunday will again reach 14 to 17 degrees.
Monday is forecast to be mild and mostly dry, with freshening southwesterly winds and highs of 14 to 17 degrees. It's the kind of day that might feel almost summery by comparison to what's coming. But by Tuesday, the Atlantic will begin asserting itself. Patchy rain and drizzle are expected to move in from the west, spreading eastward throughout the day. From midweek onward, according to Met Eireann, the pattern will shift decisively. Further bands of rain and showers will move across the country, interspersed with drier spells, but the settled weather that has defined September will be firmly in the past.
For the Ploughing Championships organizers and the crowds planning to attend, the next few days will be a study in meteorological suspense. The forecasts remain uncertain enough that hope persists—the GFS model still offers the possibility of dry conditions through the event. But the ECWMF model's warning of Thursday's heavy rain suggests that by week's end, Ireland will be thoroughly soaked.
