How should I read the live forecast above for Seaham?

What is Seaham’s typical climate through the seasons?
Seaham, on the County Durham coast, has a maritime climate: mild winters, cool summers and rain spread across the year. Winter daytime highs usually sit in the low to mid single figures, with frost possible on clear nights. Summer highs reach the mid to high teens, occasionally touching the low 20s. Rainfall is moderate, with autumn and winter the wettest periods. Wind is a constant feature, especially along the seafront.
How do local geography and the coast affect Seaham’s weather?
Seaham faces the North Sea, so onshore winds bring cool, moist air, often producing haar (sea fog) in spring and early summer. The town sits on a low cliff line, with no major hills to block incoming weather systems. The urban area adds a slight warmth, but the sea keeps summer temperatures lower than inland spots such as Durham.
When is the best time to visit Seaham and what should I pack?
Late spring (May to early June) and early autumn (September) offer the best balance of mild weather and fewer rainy days. Pack layers, a water‑resistant jacket and sturdy footwear whatever the season. In winter, add a warm coat, hat and gloves. In summer, a light fleece is still useful for coastal breezes.

How reliable is the 10‑14 day outlook for Seaham?
Longer‑range forecasts give a general trend rather than exact timings. They are useful for planning trips, but day‑to‑day details become less accurate after about 7 days. The live forecast above updates daily, so check it again closer to the time. For the broader picture, see our 10‑day forecast page.
Does it rain a lot in Seaham?

How does Seaham’s weather compare with inland County Durham?
