The best time to visit St Ishmaels is typically during the warmer months, from late spring to early autumn, specifically May to September.During these months, the weather is generally milder and there's more sunshine, making it ideal for exploring the Pembrokeshire Coast Path and enjoying the local beaches. You'll find most local attractions, shops, and eateries are fully open and operating with extended hours. This period is particularly good for families looking to enjoy outdoor activities like rock pooling, cycling, or simply spending a day by the sea.Couples often appreciate the slightly quieter periods at the very beginning or end of this window, such as May or September.
