Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Snæfellsnes Peninsula during Jun–Sep?
Peak season. Long daylight (effectively continuous in late June), all roads including Route 570 over Snæfellsskarð pass open, full Snæfellsjökull glacier-tour schedule, and the warmest weather.
Shoulder season (May, 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–Apr, 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.
