After August swung from scorching heatwaves to full-on washouts, September looks set to continue the drama. Expect blustery winds, low-pressure systems from the Atlantic, and plenty of rain. Some dry spells might pop up, but expect mostly a damp gray sky. Even when the sun decides to make a cameo, it’ll be brief, leaving you wondering if it was ever really there.
Week 1 (1–7 Sept): Wettest in the southwest, west, and northwest. Average Temperatures.
Week 2 (8–14 Sept): Slightly drier, maybe some rare sunny breaks. But it's still Ireland in September, so don't get your hopes up.
Week 3 (15–21 Sept): Uncertain, but still mostly disappointing. Rain around average, highs slightly above normal.
Week 4 (22–28 Sept): Low pressure may dominate, so more rain incoming. Temperatures remain…you guessed it, average. Keep in ;ind the 4th week of September is still far ahead to the forecast for it is fairly uncertain.
Bottom line: Aperol Spritz, beer gardens and pints on Drury Street are over. Pack your coat, grab your umbrella, and enjoy the fleeting sunshine when it dares to show up. Don’t say we didn’t warn you — September isn’t messing around.
