Best time to visit Ireland: weather and seasons by month
Go in May, June or September. May is often the driest and sunniest month, June has the longest days, and September keeps settled weather with the sea at its warmest and schools back. Avoid late July and August on the west coast unless you book cars and beds early, and skip December to February for coastal trips.

The table below pairs the month verdict with what it costs you in money and crowds. Prices are 2026 estimates for a mid-range double room in Dublin; the west runs similar or higher in July and August.
| Month | Verdict | Crowds | Price | What it means |
|---|---|---|---|---|
| January | Skip for coast | Low | Low | Short, wet, windy days; Dublin pubs and museums |
| February | Skip for coast | Low | Low | Cold and wet; cheap outside the St Brigid's weekend |
| March | Mixed | High | High | St Patrick's week fills Dublin at peak prices; rest of the month quiet |
| April | Go | Medium | Medium | Spring, lambs, longer days; Easter weekend busy |
| May | Best | Medium | Medium | Often the driest, sunniest month; Skellig trips start mid-May |
| June | Best | High | High | Longest days; best month for the west before school holidays |
| July | Caution | High | High | Peak season; book cars and B&Bs early, Galway fills |
| August | Caution | High | High | Warmest but busiest roads on the Ring of Kerry and at the Cliffs |
| September | Best | Medium | Medium | Schools back, sea at its warmest, often settled: strong for driving |
| October | Go | Medium | Medium | Autumn storms begin; Halloween and mid-term week at the end |
| November | Skip for coast | Low | Low | Dark and wet; some rural B&Bs and attractions close |

Month by month
Spring (April–May) is the sweet spot for a first trip. Days stretch past 8pm by late May, hedgerows and gardens are at their best, and the west is workable before the school rush. Easter weekend and the first Monday of May are the two dates to plan around.
Summer (June–August) gives you the longest days and the warmest sea, but it also brings the coaches. June is the best of the three for the west: you get the light without the July crowds. In July and August, book rental cars and B&Bs weeks ahead, and drive the Ring of Kerry and the Cliffs of Moher early in the morning or after 4pm.
Autumn (September–October) is the connoisseur's window. September often holds settled weather, the sea is at its warmest for swimming, and the roads empty once schools return. October turns wetter and windier, with Halloween festivals and a bank holiday at the end of the month.
Winter (November–February) is for cities, not coastlines. Daylight drops to about 7.5 hours in December, Atlantic storms close cliff paths and island ferries, and some rural B&Bs shut for the season. Dublin, Galway and Cork still work well: museums, trad sessions and short, cheap flights.
Weather by region
Ireland is small but the rain is not evenly spread. The east, around Dublin and Wicklow, is the driest part of the country and rarely goes above 25 °C or below freezing. The west coast, from Galway up through Mayo and Donegal, sees rain on most days, though rarely all day. The south-west, Kerry and West Cork, is the mildest in winter but also the wettest, which is why sub-tropical gardens grow there.
Whatever month you pick, pack waterproofs and layers. Summer highs sit at 17–20 °C, and a wet, windy 14 °C day in July is normal. Daylight runs from about 7.5 hours in December to about 17 in June, which matters more than temperature for planning a driving trip.
| Region | Where | Best months | Watch out for |
|---|---|---|---|
| Dublin and the east | Dublin, Wicklow, Boyne Valley, Kilkenny | May–August | Rarely extreme; driest part of the country |
| West coast | Galway, Connemara, Clare, Mayo, Donegal | May–August | Rain most days; winter storms close cliff paths and ferries |
| South-west | Kerry, Dingle, West Cork | May–September | High rainfall; Ring of Kerry fills with coaches in July–August |
Cost and crowds by season
Prices track the school calendar more than the weather. January, February and November are the cheapest months for flights and rooms, with the exception of St Brigid's weekend in February. March is split: St Patrick's week is the most expensive week of the year in Dublin, while the rest of the month is quiet and cheap.
July and August are peak everywhere, and the west coast is the tightest: Galway beds sell out around the Arts Festival and the Races in late July. September and October give you shoulder-season prices with most attractions still open. From November, some rural B&Bs and smaller attractions close until spring, so check opening dates before you commit to a remote itinerary.
For a full breakdown of what a day costs, see the travel cost page.
- Cheapest: January, February, November (outside holidays)
- Best value for good weather: May, June, September
- Most expensive: St Patrick's week in March, late July and August
- Quietest with everything open: late April, early June, late September
Events and holidays that change your trip
St Patrick's Day on 17 March is the single biggest date in the calendar. Parades run in every town and Dublin holds a multi-day festival; hotels book out and prices peak. If you want the atmosphere, book months ahead. If you want quiet roads, avoid that week entirely.
Christmas and St Stephen's Day, 24–26 December, shut almost everything: no public transport on Christmas Day, pubs closed on the 25th and limited services on the 26th. New Year's Day brings reduced transport and closed shops. Bank holidays on the first Monday of May, June and August fill west coast and Dublin hotels for long weekends. The last Monday of October brings Halloween festivals and school mid-term week.
| Date | What happens | Impact |
|---|---|---|
| 17 March | St Patrick's Day parades and Dublin festival | High: peak prices, book ahead |
| 24–26 December | Christmas and St Stephen's Day | High: no transport on the 25th, pubs closed |
| 1 January | New Year's Day | Medium: reduced transport, shops closed |
| First Monday of May, June, August | Bank holiday long weekends | Medium: west coast and Dublin hotels fill |
| Last Monday of October | October bank holiday and Halloween | Medium: festivals and school mid-term week |
| Late July | Galway Arts Festival and Races | High: Galway beds sell out |
How to decide
If your dates are fixed, match the trip to the season rather than the other way round. December to February suits a city break in Dublin, Galway or Cork with museums, pubs and short drives. April to early June and September to mid-October suit a driving trip around the west or south-west. Late June to August suits families tied to school holidays, but you must book cars and beds early and start each day before the coaches.
If your dates are flexible, aim for the second half of May or the first half of June for the west, or September for Kerry and West Cork. Both give you long days, open attractions and manageable crowds. Use the month picker to compare your own dates against weather, crowds and price.
- City break: any month, but November–February is cheapest
- West coast driving: mid-May to mid-June, or September
- South-west and islands: June or September
- Family trip: late June or early September to dodge peak prices
- Avoid if you want quiet roads: St Patrick's week, late July, August
Questions people ask
What is the best time of year to visit Ireland?
May, June and September. May is often the driest and sunniest, June has the longest days, and September keeps settled weather with the sea at its warmest and schools back. July and August are warmest but busiest and priciest, especially on the west coast.
When is the cheapest time to visit Ireland?
January, February and November, outside St Brigid's weekend in February. Flights and rooms are at their lowest and crowds are thin. The trade-off is short daylight, wet and windy weather, and some rural B&Bs and attractions closed for the season.
What is the weather like in Ireland each month?
Summer highs are 17–20 °C and winter days hover around 5–9 °C, with rain possible in every month. May is often driest, July and August warmest, and November to February wettest and stormiest, especially on the west coast. Daylight runs from about 7.5 hours in December to about 17 in June.
Is it worth visiting Ireland in winter?
Yes for cities, no for coastlines. Dublin, Galway and Cork work well in winter with museums, pubs and trad sessions, and prices are low. Atlantic storms close cliff paths and island ferries, and daylight is short, so plan indoor days and short drives.
Should I avoid July and August in Ireland?
Not avoid, but plan around them. Book rental cars and B&Bs weeks ahead, drive the Ring of Kerry and the Cliffs of Moher early morning or after 4pm, and expect Galway to be full around the Arts Festival and Races in late July.
Do I need a visa to visit Ireland?
Most visitors from the US, UK, Canada, Australia, New Zealand and the EU do not need a visa for a short tourist stay. Other passports should check the current rules before booking. See the visa requirements page for details.
