Newquay’s maritime climate means mild winters and cool summers, with the best chance of settled weather between May and September – but expect rain in any month.
When is the best time to visit Newquay?
July and August bring the highest temperatures (averaging 19–20°C) and longest days, but also the largest crowds and peak accommodation prices. For a quieter trip with still-pleasant conditions, aim for late May, June or early September. Pack a waterproof jacket and layers year-round; even a summer afternoon can turn breezy and damp. School holidays in Cornwall fill up fast, so book early if travelling with children in late July or August.
What is the typical weather pattern in Newquay?
Prevailing south-westerly winds push Atlantic weather systems ashore, so Newquay sees frequent cloud and rain – about 800–900 mm annually. Winter lows hover around 4–5°C, and frost is rare near the coast. Spring often brings a mix of bright spells and showers; autumn can be stormy but also offers calm, golden days. The live forecast above gives the most up-to-date picture for the next few days.
Where can I find a reliable Newquay weather forecast for 14 days?
The Met Office and BBC Weather both provide 14-day outlooks for Newquay. The BBC’s forecast includes a daily breakdown of wind, UV and rainfall, helpful for planning beach days or coastal walks.
Is the sea warm enough to swim in Newquay in spring?
Sea temperatures off Newquay reach about 10°C in April and 13°C in May – cold for most without a wetsuit. Tolerable swimming usually starts in June when the water warms to 15°C and above.
What should I pack for a weekend in Newquay in October?
October averages 12–14°C with frequent rain. Bring a waterproof coat, warm jumper, sturdy footwear and a windproof layer. Sunscreen is still useful on clear days, and a hat will help against the Atlantic breeze.
