The live forecast above gives Seaton’s most reliable view for today and the coming days. With the town set on the Jurassic Coast, expect a maritime mix of sunny spells and light showers – typical for this corner of Devon.
What is the outlook for Seaton this week?
Seaton’s weather stays changeable as Atlantic systems brush the south-west. The live forecast shows a midweek ridge bringing drier conditions, then cloud and patchy rain returning by Friday. Coastal breezes keep temperatures a few degrees cooler than inland Exeter, so a light jacket is useful even on sunny afternoons.
How does Seaton’s position affect its weather?
Sheltered by the Axe Valley and open to Lyme Bay, Seaton often misses the heavier rain that hits Dartmoor. Sea fog can drift in during spring, but summer sea breezes keep the coast fresher than many Devon towns. For longer-range planning, the live forecast covers the next 14 days – similar to a BBC Weather Seaton 14-day check – while those looking up weather in Seaton Devon 10 days will find it matches the same data.
When is the best time to visit Seaton for fine weather?
May to September offers the warmest and driest conditions. July and August average 20°C, but sea breezes often keep the coast comfortable. Early autumn can also bring settled spells with fewer crowds.
Does Seaton get a lot of rain?
Seaton is drier than inland Devon, averaging 800mm a year – less than Exeter or Dartmoor. Rain tends to be light, with most falling in autumn and winter. Summer showers are brief.
How accurate is the live forecast for Seaton?
The live forecast uses Met Office data and is updated regularly. For short-term planning it is very reliable; longer-range indications (beyond 5 days) give trends rather than precise timings. Always check again before travel.
