Best time to visit Galway

June is the best month in Galway, scoring 66 out of 100, with January the weakest at 25. The 41-point spread means timing is worth planning around without being decisive. The good window runs May to September — 5 months within ten points of the best.

July is the warmest month at 19.8 °C and January the coolest at 7.5 °C — a 12.3 °C spread across the year. It never reaches 30 °C in an average year, which takes heat off the list of reasons to avoid any particular month. 21 nights a year dip below freezing.

There is a real wet season here. January, July, August, October, November and December carry the rain — up to 20 wet days in a month — while April drops as low as 14. That 6-day gap is the biggest single difference between a good month and a bad one in Galway, and it moves further than the temperature does.

Daylight swings hard — 16.9 hours at midsummer against 7.6 at midwinter. That 9.3-hour difference changes how much fits into a day more than the temperature does.

The three strongest months are June, July, September. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
