The best time to go to Stackpole is during the late spring and summer months, from May to September, when the weather is generally at its finest for outdoor activities.May and June offer pleasant temperatures, fewer crowds, and the opportunity to see the local flora, such as bluebells in Stackpole Woods, at its peak. This period is ideal for walkers and nature enthusiasts looking to explore the coastal paths and woodlands without the peak season bustle.July and August are the warmest months, superb for enjoying the beaches at Barafundle Bay and Broad Haven South. These months are excellent for families, as the sea is warmer for swimming and there are more daylight hours for exploring the Stackpole Estate, including activities like coasteering or kayaking.September provides a lovely balance, with the sea still warm enough for swimming, fewer crowds than the height of summer, and comfortable temperatures for walking.
