Pembrokeshire’s weather is famously mild and changeable, with the Gulf Stream keeping winters warmer and summers cooler than inland Wales. Expect rain year-round, but the sunniest, driest months are May, June, and September, making them the best time for coastal walks.
The live forecast above gives the most current outlook for the Pembrokeshire Coast National Park. Use it alongside the details below to plan your trip.
What is the best time to visit Pembrokeshire for weather?
For the most reliable sunshine and low rainfall, aim for late spring (May to June) or early autumn (September). July and August are warmest but busiest, with higher chance of school-holiday crowds. Winter (November to February) is quieter but brings frequent storms and shorter days.
What should I pack for a Pembrokeshire holiday?
Layers are essential. A waterproof jacket and sturdy walking shoes are non-negotiable, even in summer. In spring and autumn, add a fleece or mid-layer. Sunscreen and a sun hat are wise for June to August, when UV levels can be strong despite the breeze.
Is Pembrokeshire warmer than the rest of Wales?
Yes, the coast is typically 1–3°C milder than inland Wales, thanks to the Atlantic’s warming influence. Frost and snow are rare on the coast, though common just a few miles inland.
Does Pembrokeshire get weather warnings often?
Yes, especially for wind and rain in autumn and winter. Check the live forecast above and the Met Office for any Pembrokeshire weather warning updates before heading out on coastal paths.
Can I rely on a 14-day forecast for Pembrokeshire?
Forecasts beyond 7–10 days have limited accuracy for this region due to Atlantic weather systems. A 10-day forecast is more reliable for planning walks or days out.
