Two Beaches for Swimmers

Llandudno's two beaches offer rather different swimming experiences. North Shore, the main beach, faces north across the Irish Sea and can experience choppier conditions when the wind is onshore. The beach shelves gradually and the Blue Flag designation reflects consistently good water quality. On calm, sunny days in summer it is an excellent swimming beach, and the backdrop of the promenade and the Great Orme adds considerably to the pleasure of the occasion.

West Shore faces east across the Conwy estuary, which means it is generally more sheltered and the water calmer. The tidal estuary character means conditions can vary depending on the state of the tide, and the water quality, while good, has a different character from the open-sea beaches. For a quieter swim with mountain views rather than open sea, West Shore is a very pleasant option. Dogs can also accompany you to West Shore year-round, which North Shore does not allow in summer.

Water Temperature and the Swimming Season

The Irish Sea is not the warmest of Britain's coastal waters. Sea temperatures at Llandudno peak in August at around 16 to 17 degrees Celsius, which most experienced swimmers would describe as refreshing rather than warm. The water temperature drops through the autumn and winter to as low as 7 or 8 degrees in February and March, making cold-water swimming genuinely demanding outside the summer months. The season for casual sea bathing is roughly June to September, with July and August the warmest.

Wild swimming and cold-water swimming have grown enormously in popularity in recent years, and both Llandudno beaches attract year-round swimmers who embrace the cold as part of the experience. If you are new to cold-water swimming, the relatively sheltered conditions at West Shore make it a good place to acclimatise. A wetsuit extends the comfortable swimming season considerably, bringing conditions in October and May into the range that most recreational swimmers can enjoy. The key at any time of year is to know your limits, check conditions before entering, and never swim alone.

Safety Information

Neither North Shore nor West Shore has permanent lifeguard cover; swimming safety is the swimmer's own responsibility. The beaches are generally safe for competent swimmers in calm conditions, but as with any tidal water, conditions can change. Check the weather forecast and the wind direction before your swim; an offshore breeze at North Shore means the sea surface may appear calm from the shore while currents are running strongly further out. If in doubt, don't go in.

Tide times are freely available online and are worth checking before you visit, particularly at West Shore where the tidal range affects the extent of the beach and can influence currents in the estuary. At North Shore, the main safety consideration is the state of the sea rather than tidal currents, but incoming tides can cut off sections of the beach at the foot of the Great Orme on the western end; be aware of where you are relative to the tide.

The water quality at North Shore is consistently good — the Blue Flag designation involves regular testing throughout the season — but heavy rain can temporarily affect water quality near stormwater outflows, as at any beach. Local notifications are posted when conditions fall below the excellent standard. For the most up-to-date water quality information, check the Bathing Water Quality monitoring service before your swim.

After Your Swim

One of the pleasures of sea swimming at Llandudno is the proximity of good places to warm up afterwards. The West Shore Beach Cafe is perfectly positioned for post-swim coffee and cake, with dogs welcome and views across the estuary. On North Shore, the promenade cafes and the town centre are a few steps from the beach, offering the full range of warming options from fish and chips to barista coffee at Providero on Mostyn Street.

For those who prefer their swimming to come with a roof and heating, the Empire Hotel & Spa has an indoor pool, sauna and steam room, available to non-residents as well as hotel guests (check the hotel for current access arrangements). This makes it a particularly good option for winter and rainy-day swimming when the sea looks less inviting.
