Newquay sää — syyskuu

Regulars are specific the local saying here is "we get a lot of weather," genuinely capable of turning warm and sunny or wet and cool within the same week, settled spells the exception rather than the rule. Our row backs that mild, genuinely wet read, 18C over 12.7C nights feeling 11C, with a substantial 99.5mm of rain across 14.5 days and a real 25.7 kph wind. Regulars are consistent if one coast of the peninsula looks poor, the other side can look completely different, with several long-time residents specifically rating this month as more reliably pleasant than June despite that reputation. Forecasting more than a few days out here is treated as genuinely pointless. The sea sits at 16.8C. The record: 8 hours of sun, humidity 82 percent and AQI 44.

Regulars are specific that this month suits surfers of every level, with genuinely fewer people in the water than a typical Tuesday in the busy summer months - a real trade for the colder water. Our row backs the cold spring read, 13.1C over 6.9C nights feeling 3C, with 63.5mm of rain across 11.9 days and a real 24.7 kph wind, against a properly cold sea at 10.8C, wetsuit territory regardless of the air. Regulars also flag that Cornwall's weather is notoriously localized, recommending checking a dedicated local forecast or radar rather than a generic regional one before planning a surf session. The record: humidity 78 percent, 10.1 hours of sun and AQI 45.

Regulars put April and May among the best weeks here and warn in the same breath that Cornish weather is local and unreliable - two beaches a few miles apart can have different days, and the forecast is pot luck. Our row gives 16C afternoons that feel like 14C in a 23 kph wind, 9.5C nights, and 54.1mm across 9.7 days. The water is the part visitors misjudge: the sea reaches 12.4C this month and rarely passes 18C even in summer, so a wetsuit is not optional at Fistral, it is the equipment. What May does have is light, 15.5 hours of it with 11.3 of sun, and beaches that are not yet full. The record: humidity 79 percent and AQI 45.

June is the month Newquay regulars name for coming before the crush: the schools break up in mid-July, so this is the last stretch of summer weather without them, and September after they go back is the other one. It is already peak season for booking, though, so beds go early. On surf they are positive - mid-June waves can be properly rough and the water busy with surfers - and the local habit is to check a surf forecast rather than a weather one, magicseaweed or windguru alongside the usual. Our row's 18.4C reads as 17C and the sea is 16.6C, so this is a wetsuit month whatever the sky does. The record: 12.4C nights, 74.3mm across 12 precipitation days, 11.2 hours of sun, a 22.8 kph wind and 16.4 hours of daylight.

July in Newquay is Cornwall's usual bargain: unpredictable weather in exchange for the best of the coast. Regulars will not promise beach heat - some Julys are boiling, others are not - and the sea is cold enough that hiring a wetsuit at Fistral is normal rather than cautious. Our row puts it at 16.6C. On crowds the split is by hour and by term: school holidays fill the town and the parking, and early morning is the time regulars name for clean conditions and space. Fistral's summer surf is a consistent one-to-four-foot break, which is why every learner in the county is on it. The record: 19.9C days that feel like 19C, 14C nights, 11.8 precipitation days carrying 63mm, 11.2 hours of sun and a 23 kph wind.
