With August 2025 feeling like a distant memory, let’s say hello to September!
Anglesey in September 2025 is maybe one of my favourite months on the island. The weather’s mild, it’s generally quieter with the kids back in school, and autumn starts to bed in.
If you’re looking for ways to fill your early autumn break on Anglesey, then let’s see if any of these events might pique your interest. Some events require you to book in advance– be sure to check with the vendor to avoid disappointment.
