Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Galway during May–Sep?
The warmest and driest period — Galway Arts Festival (July) transforms the city. Long days (light until 10:30pm in June).
Shoulder season (Apr, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
