Why visit Cliffs of Moher during May–Sep?
Lengthening days with frequent showers but improving conditions. Puffins return to the cliffs in late April; by May the seabird colonies are full and visible.
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.
