The best time to go to Milford Haven is during the summer months, from June to August, when the weather is warmest and most suitable for outdoor activities.During this period, you can expect average temperatures ranging from 15°C to 20°C (59°F to 68°F), with longer daylight hours. This makes it ideal for exploring the Pembrokeshire Coast Path, taking boat trips to Skomer Island for puffin watching, or enjoying the local beaches. Families often find this time particularly good for coastal excursions and wildlife spotting.The shoulder seasons of May and September also offer a pleasant experience. While slightly cooler, with average temperatures between 12°C and 16°C (54°F to 61°F), these months generally see fewer crowds and can still be quite sunny. This period is great for couples who prefer a more tranquil trip while still enjoying good weather for walking and sightseeing.
