The best time to go to Pembroke is from late spring to early autumn, specifically from May to September, when the weather is generally mildest and most reliable for enjoying outdoor activities.May and June offer pleasant temperatures, fewer crowds than the peak summer months, and longer daylight hours, making it ideal for exploring the Pembrokeshire Coast Path or visiting historical sites like Pembroke Castle. The wildflowers are also in full bloom during this period, adding to the scenery. This time of year works well for couples looking for a relaxed yet active trip.July and August are the warmest months and are superb for beach holidays and water sports. The sea temperatures are at their highest, and the towns and villages along the coast are bustling with activity. Families will find this period particularly good, with plenty of options for children, from sandy beaches to boat trips. However, it's also the busiest time, so booking accommodation and popular attractions in advance is advisable.September offers a good balance of warm weather and fewer visitors as the school holidays end. The sea can still be warm enough for swimming, and the coastal paths are quieter.
