Ireland in spring: weather, crowds and things to do

Spring in Ireland is a slow warm-up, not a switch. March still feels like winter: short days, wind off the Atlantic and rain that arrives sideways. April adds light and lambs; May is the month locals bet on, often the driest and sunniest of the year, with the longest evenings before the June peak.

Temperatures are mild rather than warm. Daytime highs sit somewhere around 9–15 °C across the season (check), with nights still cold enough for a warm layer. The east (Dublin, Wicklow, Kilkenny) is the driest part of the country; the west coast (Galway, Connemara, Clare, Mayo, Donegal) and the south-west (Kerry, Dingle, West Cork) see rain on most days, though seldom for the whole day. Atlantic storms are less frequent than in winter but can still close cliff paths and island ferries.

Daylight is the real prize. Spring days are far longer than in winter and still short of June's roughly 17 hours (check), which is what makes a spring driving trip work: you can see two or three stops in a day and still eat dinner in daylight.

Spring is the shoulder season, and that is the point. Outside two spikes, roads, car parks and B&Bs are far quieter than in July and August, when the Ring of Kerry and the Cliffs of Moher fill with coaches. Prices follow the same curve: medium in April and May, low in most of March.

The spikes are worth planning around. St Patrick's week (17 March, with a multi-day festival in Dublin) is the busiest and most expensive week of the spring — hotels book out and prices peak. Easter weekend is medium-impact: busy, with some businesses closed on Good Friday, which is not a public holiday in Ireland. The first Monday in May is a bank holiday, and west coast and Dublin hotels fill for that long weekend.

If you want quiet, aim for late April or the second half of May, avoiding the Easter and May bank holiday weekends. Book Dublin hotels around 17 March and Easter, and west coast beds for the May bank holiday, well ahead; outside those dates spring rooms are usually easier than in July and August.

Spring suits the things summer crowds make hard. Walk the cliff paths and mountain trails before the coaches arrive, drive the peninsulas without queuing for viewpoints, and take the coastal roads at your own pace. Wildflowers and nesting seabirds are at their best on the Burren and the western headlands, and gardens such as those in Kerry and West Cork are coming into leaf.

It is also a good season for towns. Dublin's museums, Kilkenny's medieval streets, Galway's music pubs and Cork's food markets are all indoor-friendly when a shower passes. Spring lamb appears on menus, and a bowl of Irish stew still makes sense on a cold evening.

Two spring-specific notes. Skellig Michael boat landings are seasonal and weather-dependent, with the start date varying by year (check), so build in a spare day if that trip matters. And St Patrick's Day itself is a reason to come, not a reason to avoid Ireland — just accept the Dublin prices and book months ahead.

Pack for four seasons in one day, because that is what spring delivers. The essentials are a waterproof shell with a hood, a warm mid-layer (fleece or light down), quick-drying trousers and shoes with grip for wet paths. Skip the umbrella for exposed coasts; wind makes it useless.

Add a hat and gloves for March and for evenings anywhere in spring, plus a swimsuit if you plan a seaweed bath or a dip — the sea is cold but some travellers do it. Bring a power bank for long driving days, a refillable bottle, and a small daypack that keeps rain off a camera. Sunscreen is not wasted in May, when the sun can be stronger than the temperature suggests.

If you are renting a car, pack light: Irish country roads and B&B rooms are small, and you will be moving between bases.

This page describes spring as it happens in Ireland, in the Northern Hemisphere: March, April and May. If you are reading from Australia, New Zealand, South Africa or South America, your own spring falls in September, October and November — the opposite half of the year.

That matters for planning. A traveller from Sydney or Auckland visiting Ireland in April is leaving autumn at home and arriving in spring, so the packing advice is the same but the body clock and wardrobe expectations are not. If you want warm weather at home and in Ireland at the same time, aim for an Irish summer (June–August) rather than an Irish spring.
