The best time to visit Lamphey is generally between late spring and early autumn, from May to September, when the weather is mildest and the days are long.This period offers the best conditions for exploring the Pembrokeshire Coast National Park, which is a key attraction for visitors to Lamphey. You'll find it pleasant for walking parts of the Pembrokeshire Coast Path, visiting nearby beaches like Freshwater East or Manorbier, and enjoying outdoor activities.For those who enjoy a quieter experience and don't mind slightly cooler temperatures, May, early June, or September can be particularly appealing. The main tourist season is in full swing during July and August, meaning more activities are available, but also more visitors.
