What is Haverfordwest’s typical climate like through the seasons?
Haverfordwest has a mild maritime climate, strongly influenced by the Atlantic. Winters are cool and wet, with average daytime highs in the single figures Celsius and frequent rain. Spring brings longer dry spells and temperatures gradually rising into the low teens. Summers are mild, often reaching the high teens or low twenties, though rain remains possible. Autumn sees increasing wind and rain as Atlantic lows return. Frost is rare near the coast.
How do local geography and the coast affect the weather?
Haverfordwest sits in a valley on the Western Cleddau river, about 10 miles inland from the coast. This valley can trap mist and fog on calm mornings, while the surrounding hills sometimes shelter the town from the strongest winds. However, the proximity to the Irish Sea means cloud and rain can arrive quickly. The coast itself, including nearby Tenby and Burton, often has slightly milder temperatures and higher wind speeds.
When is the best time to visit Haverfordwest, and what should I pack?
Late spring (May to June) and early autumn (September) offer the best balance of mild temperatures and lower rainfall. Pack layers: a waterproof jacket is essential year‑round, along with a warm mid‑layer for cooler evenings. Comfortable walking shoes are recommended for exploring the town and the nearby national park. Sunscreen and a hat can be useful on clearer summer days.
