The climate in Galway, located on the west coast of Ireland, can be described as temperate oceanic. This means there are no extreme temperature fluctuations throughout the year. The weather is famously changeable, so you might experience sunshine and rain all in the same day.

Summers (June–August) are cool, with averages around 14-15°C and highs reaching 17-18°C. Spring and autumn are transitional seasons with moderate temperatures.

One of the main features of Galway's weather is high humidity and frequent precipitation throughout the year.

In Galway, precipitation is an integral part of the climate and is distributed fairly evenly throughout the year, with no distinct dry or rainy season. The city is known for its damp weather, and travelers should be prepared for rain at almost any time of year.

The "driest" period is generally May. This month averages the lowest amount of precipitation (about 2 mm) and the fewest rainy days (approximately 14). On the other hand, the wettest months in terms of the number of rainy days are August and October, when precipitation is recorded on average 20 days. In terms of total precipitation volume (about 4 mm), February, March, November, and December also rank among the wettest.

Precipitation in Galway most often takes the form of light or moderate rain rather than heavy downpours. This is evidenced by the relatively low monthly rainfall totals despite the high frequency of rainy days. Even in the "driest" months, it rains on nearly half the days. Given the mild temperatures year-round, especially in winter, snowfall in Galway is a rare occurrence.

When planning a trip to Galway, be prepared for the changeable Irish weather, which is famous for its unpredictability. The key to packing is layering. The weather can change drastically even within a single day, so being able to easily remove or add layers will keep you comfortable. Given that Galway averages 14 to 20 rainy days per month, a waterproof and windproof hooded jacket is an absolute necessity year-round. Comfortable waterproof footwear is also essential, as you'll likely want to explore the city on foot regardless of any puddles.

In summer, from June to August, average temperatures hover around 14-15°C, peaking at about 17-18°C. During this period, you'll need T-shirts, long-sleeved shirts, light trousers, and a sweater or fleece for evening walks or cooler days. Don't forget sunscreen — the Irish sun can be deceptive. In winter, from December to February, average temperatures drop to 5-6°C. Warm clothing is essential: sweaters, thermal layers, a warm jacket, a hat, a scarf, and gloves. In spring (March–May) and autumn (September–November), the weather remains cool and damp, with temperatures ranging from 6°C to 13°C, so layered clothing including warm and waterproof items will be your best choice.
