Lostwithiel has a temperate maritime climate, with mild winters and cool summers typical of south-east Cornwall. The live forecast above shows current conditions; rain is frequent throughout the year, especially in autumn and winter, so a waterproof layer is often useful.
What is the typical weather pattern in Lostwithiel?
Lostwithiel sits inland on the River Fowey, which means it can be slightly warmer than the coast in summer but cooler and foggier in winter. Rainfall is spread fairly evenly, with October to January being the wettest months. Snow is rare, but frost occurs on clear winter nights. The prevailing south-westerly winds bring moist air from the Atlantic, so cloud cover is common.
How does the weather affect local activities?
The town’s historic centre and riverside walks are best enjoyed in late spring (May–June) or early autumn (September), when temperatures are pleasant and rainfall lower. Summer highs typically reach the low 20s °C, while winter lows hover around 2–4 °C. Flooding can occur after prolonged rain, especially near the river, so it’s worth checking the live forecast above and local flood warnings before planning a visit.
Is Lostwithiel prone to flooding?
Yes, parts of Lostwithiel near the River Fowey can flood after heavy or prolonged rain. The Environment Agency issues flood alerts; check the live forecast above and local warnings if you’re planning to stay near the river.
What is the best time to visit Lostwithiel for fine weather?
Late spring (May–June) and early autumn (September) offer the best balance of mild temperatures and lower rainfall. July and August are warmer but can be busier and more humid, with occasional thundery showers.
How reliable are 10‑day forecasts for Lostwithiel?
