August is one of the warmest months of the year in Cornwall, although conditions can vary more than many visitors expect. While some days feel truly summery, others can be cooler or breezier, particularly along the north coast.
Average daytime temperatures usually range between 19°C and 22°C, with warmer days occasionally reaching the mid 20s during settled weather. Evenings are generally mild, often sitting between 13°C and 16°C, which makes outdoor dining and coastal walks comfortable.
Rainfall is possible in August, but it tends to arrive in short spells rather than prolonged wet periods. Many weeks include a mix of sunny days, light cloud, and occasional showers. Compared to July, August often feels slightly less stable, but still very suitable for outdoor activities.
Sea temperatures are at their warmest of the year, usually around 17°C to 19°C. While still cool compared to Mediterranean destinations, this is one of the best months for swimming in Cornwall, particularly on calm days and in sheltered bays.
August is the busiest month of the year in Cornwall. UK school holidays, summer weather, and peak travel demand all contribute to high visitor numbers across the county.
Popular coastal towns, well known beaches, and major attractions are noticeably busier than earlier in the summer. Traffic on main routes such as the A30 can be heavy on changeover days, and parking near beaches often fills early.
The areas that tend to feel the busiest in August include:
Large family friendly beaches such as Fistral Beach, Watergate Bay, and Perranporth
Coastal towns including St Ives, Padstow, and Newquay
Easily accessible beauty spots and short coastal walks
That said, how busy Cornwall feels depends heavily on timing and location. Early mornings are often calm, even at popular beaches, while evenings tend to feel relaxed and sociable rather than overwhelming. Inland areas, lesser known coves, and longer coastal walks remain much quieter throughout the day.
With thoughtful planning and a flexible daily routine, Cornwall in August can still feel enjoyable rather than overcrowded.
Choosing the right area to stay in Cornwall plays a major role in shaping your experience, particularly during peak summer. Different parts of the county offer very different atmospheres, and some cope with August crowds better than others.
North Coast Cornwall
The north coast is one of the most popular areas to stay in August. Long sandy beaches, reliable surf, and dramatic coastal scenery attract families, surfers, and active travellers. Towns such as Newquay, Perranporth, and Polzeath are busy during peak summer but are well equipped to handle higher visitor numbers.
The Headland Hotel, Newquay
Set above Fistral Beach, The Headland Hotel is one of Cornwall’s most iconic coastal hotels. It offers sea views, direct access to coastal walks, and a full spa, making it a comfortable base during August. The size of the property and its facilities help it cope well during peak season.
South Coast Cornwall
The south coast tends to feel calmer and more sheltered than the north. Harbours, coastal paths, and gentler sea conditions make this area appealing for couples and travellers looking for a slower pace. Fowey, Mevagissey, and the Helford area are particularly popular in August.
The Old Quay House, Fowey
Located directly on the harbour, The Old Quay House offers a relaxed and refined stay in one of Cornwall’s most attractive coastal towns. Its central location suits visitors who want to explore on foot, enjoy boat trips, and spend evenings dining along the waterfront.
West Cornwall
West Cornwall is home to some of the county’s most scenic coastline, from the beaches around St Ives to the quieter stretches near Sennen and Mousehole. While St Ives itself can feel very busy in August, staying slightly outside the town often provides a more balanced experience.
Carbis Bay Hotel, Carbis Bay
Just outside St Ives, Carbis Bay Hotel offers direct beach access, sea facing rooms, and a quieter setting than staying in the town centre. It works well in August for travellers who want coastal scenery without being in the busiest areas during the day.
Inland Cornwall
Inland Cornwall is often overlooked during summer, but it can be an excellent base in August. Countryside locations offer quieter evenings, easier parking, and a more relaxed pace after busy days at the coast. This works particularly well if you plan to explore multiple areas of the county.
Bodmin Jail, Bodmin
Bodmin Jail offers a unique stay in the heart of inland Cornwall. This historic property combines heritage charm with modern amenities and is within easy reach of both north and south coast destinations. Its central location makes it a great base for exploring the county while avoiding the busiest coastal towns.

August is one of the best months for beach time in Cornwall, but choosing the right beach and visiting at the right time makes a big difference, especially if you prefer a quieter beach over the main popular beaches.
Beaches that work well in August
Long, wide beaches tend to cope better with peak season crowds. These include:
Perranporth Beach, which has space to spread out even on busy days
Gwithian Towans, offering extensive sand dunes and multiple access points
Watergate Bay, with plenty of room and good facilities
Family friendly beaches
Beaches with lifeguard cover, facilities, and calmer water are particularly popular in August. Crantock Beach, Summerleaze Beach, and Polzeath Beach are all strong options for families.
Quieter alternatives
Smaller coves and less developed beaches are often quieter, especially early or late in the day. Portheras Cove, Porth Nanven, and parts of the Lizard Peninsula offer a more peaceful experience.
Tide times are important in August. Some beaches are best visited at low tide, while others disappear almost entirely at high tide. Checking tide charts helps avoid disappointment and ensures your safety as the tides in Cornwall are extreme.
August in Cornwall is best enjoyed at a relaxed pace, planning activities around the weather, tides, and crowds. Long days and warm sea temperatures make it ideal for outdoor adventures, coastal exploration, and summer events.
Coastal walks and scenery
Early mornings and evenings are the best times for coastal walks in August. Sections of the South West Coast Path offer dramatic cliff views, sea breezes, and quieter conditions outside the hottest part of the day. Popular walks include Bedruthan Steps, St Agnes Head, and around St Ives Bay.
Boat trips and water activities
August is peak season for boat trips. Wildlife watching, coastal cruises, and short ferry crossings run frequently from harbours such as Fowey, Padstow, and St Ives. Kayaking, paddleboarding, and swimming are also popular thanks to warmer sea temperatures. Hiring a small boat or joining a guided tour is a great way to access quieter coves and beaches.
Towns, gardens, and attractions
Historic towns, gardens, and heritage sites are best visited early or later in the day to avoid crowds. Highlights include:
The Lost Gardens of Heligan – perfect for morning exploration
Trebah Garden – enjoy the subtropical plants and sheltered valley setting
St Ives and Padstow – wander galleries, harbours, and shops when the midday crowds are lighter
Festivals and events
August brings a wide range of food, music, and local festivals with Boardmasters being the largest and busiest. Many are centred around harbours and town centres, adding seasonal atmosphere and opportunities to sample local produce and crafts. Notable events often include seafood festivals, Cornish fairs, and music and surf festivals such as Boardmasters.
Other popular August activities
Surfing lessons on Fistral Beach or Polzeath
Cycling coastal and inland routes
Exploring hidden coves and quieter beaches like Porthcothan Bay or Kennack Sands
With thoughtful timing, August allows visitors to enjoy Cornwall’s natural beauty, culture, and coastal activities without feeling rushed or overwhelmed by peak season crowds.
August can be a great time to visit Cornwall for couples, depending on the kind of experience you are looking for. Long summer evenings, coastal dining, and warmer sea temperatures create a relaxed setting for slow days and sociable nights.
Couples who enjoy beach time, scenic coastal walks, and exploring smaller towns will still find quieter moments, especially by starting days early or staying just outside the busiest resorts.
If you are looking for complete tranquillity and empty beaches, August may feel overwhelming at peak times. However, for couples who enjoy an energetic summer atmosphere and are happy to plan around crowds, August can be a very enjoyable month to visit Cornwall.
For couples seeking a more peaceful experience, the shoulder seasons outside of school holidays such as late May, June, or September often offer milder crowds, easier parking, and calmer beaches while still providing good weather for outdoor activities and coastal exploration. These months are ideal for those who want to enjoy Cornwall’s scenery at a slower pace.
Cornwall is very family friendly in August and it is one of the most popular months for visiting with children. UK school holidays, lifeguarded beaches, and a wide range of family focused attractions make it an easy and reliable choice for summer trips.
Beaches, coastal walks, wildlife parks, and water based activities are all well suited to families, while many towns offer child friendly restaurants and facilities.
Family accommodation fills quickly in August, particularly self catering cottages and places close to beaches or major attractions. Booking accommodation and activities well in advance is strongly recommended to secure the best options.
August is one of the most expensive months to visit Cornwall. Accommodation prices peak during UK school holidays, and availability becomes limited the closer you get to travel dates.
While hotels and holiday rentals cost more than in June or early July, everyday expenses such as food, attractions, and activities remain fairly reasonable compared with many other popular UK summer destinations.
Overall travel costs in August are higher, particularly for accommodation and car hire. Booking places to stay, transport, and popular experiences well in advance helps secure better value and a wider choice.
Packing for Cornwall in August requires a bit of flexibility. While days can be warm and sunny, coastal weather can change quickly, and evenings often feel cooler, especially near the sea.
Alongside summer clothing, it is worth packing layers that can be added or removed throughout the day.
Recommended items to pack for Cornwall in August include:
Lightweight clothing such as t shirts, dresses, and shorts for warm days
A warm layer such as a jumper or light fleece for evenings and coastal walks
Comfortable walking shoes or trainers for exploring towns and coastal paths
Sandals or flip flops for beaches and short walks
Swimwear for beach days and wild swimming
A light waterproof jacket or windbreaker for sudden showers and sea breezes
Sun protection including sunscreen, sunglasses, and a hat
A small day backpack for beach gear, water, and layers
A reusable water bottle, particularly for long summer walks
Windbreak for occasional windy beach days
If you plan to spend a lot of time in the sea, a wetsuit can be useful even in August, especially on cooler or windier days. Beach towels, picnic blankets, and a portable phone charger can also make long beach days more comfortable.
