Ireland’s weather is a temperate maritime climate: mild year-round, but famously changeable. Expect rain in every season, with summer highs around 18–20°C and winter lows rarely below 2°C. Pack layers and a waterproof jacket no matter when you visit.
When is the best time to visit Ireland?
The most reliable months are May to September, offering the longest daylight and warmest temperatures. July and August are peak tourist season, so expect higher prices and crowds. For better value, aim for the shoulder seasons (May, June, September) when the weather is still pleasant. Winter (November–February) is quieter and cheaper, but days are short and rain frequent — though snow is rare in the lowlands. For a month-by-month breakdown, the live forecast above gives a quick snapshot of current conditions.
What should you pack for Ireland?
A waterproof jacket and comfortable walking shoes are non-negotiable — rain can appear without warning. Layers are key: a thermal base, a fleece, and a windproof outer. Even in summer, temperatures rarely exceed 20°C. In winter, a warm coat, gloves, and a hat are useful, but heavy snow is uncommon. If you’re heading to the west (Galway), expect more rain than in the east (Dublin). Check the BOM Weather Australia page for the latest on Australian conditions, or explore our Australia weather hub for comparisons.
Does it snow in Ireland?
Snow is infrequent in lowland areas, occurring on just a few days each winter. The west and north-west may see light accumulations, but heavy snow is rare. For updates on severe winter weather, see our severe weather warning page.
Is Ireland rainy all year round?
Rain is common in every season, but the west (including Galway) receives more than the east (Dublin). The driest months are April to June. Overall, Ireland’s annual rainfall is comparable to that of many Australian coastal cities, though it falls more steadily across the year.
How reliable is a 15-day weather forecast for Ireland?
Ireland’s changeable climate means forecasts beyond 7 days have low accuracy. For the most trustworthy outlook, refer to the live forecast above or check a weather radar for near-real-time conditions. Short-term 10-day forecasts offer a useful guide, but always be prepared for shifts.
