Weather Overview for Llandudno

Llandudno has a mild temperate climate with all four seasons and no extremes of temperature. Rainfall is quite high year round. While the resort sits on the northwest coast of Wales, it is protected from the brunt of the cool, wet weather carried by the southwest prevailing winds that come off the Atlantic by The Ormes, two rocky headlands. The resort is popular year round; in the summer for its Victorian waterfront and long bay and in the winter for skiing and tobogganing (of sorts).

Summer, from mid June till mid September, is quite a tepid affair with average highs peaking in July and August at 18°C. It can get into the low 20s and is generally warmer than other Welsh resorts to the south of the Great Orme. Night time temperatures are typically cool with an average low of 11°C in the warmest months. It can often be overcast so sunshine levels are not exceptional; June can expect six hours of sunshine per day, July and August five and September four. It rains frequently and showers are not always light. Rainfall increases towards the end of the season.

Nationalism is not particularly strong in the UK, though perhaps more so in Scotland, Wales and Northern Ireland than in England. But it comes out when on holiday. If holidaying in the UK, this generally manifests itself in a stubborn belief that there is absolutely nothing wrong with the British sea. It gets up to a peak temperature of 16°C in August; that is what’s wrong with the British sea. But no doubt you will choose to grin and bear it.

Llandudno’s North Beach is a favourite with windsurfers when a northwest wind blows. Climbing is also popular on the Great Orme and nearby Snowdonia.

Autumn, from mid September till mid November, is cool and wet. The average high temperature drops to 14°C in October and 10°C in November while night time lows drop to 8°C and 5°C respectively. Grey blankets the sky, spitting rain relentlessly. Sunshine hours reduce to three per day in October and four in November. It rains on around twenty days in each month; this is the wettest time of year. But fell walking would not be the same without losing a shoe or two in the mud and having your map dissolve and disintegrate between your fingers.

Winter, between mid November and mid March, is technically mild but actually quite cold and gloomy. The average high temperature quickly drops below 10°C at the end of November and down to the yearly low of 7°C for January and February. The night time average low does not fall below 2°C. Of course, this is nowhere near as cold as in other places of similar latitudes, for instance central Newfoundland and the far north of the Netherlands, but this does not make winter in Llandudno cheery. Sunshine levels cling to one hour per day until February when they jump to three. It continues to rain steadily though showers become lighter as the season progresses and rainfall reduces quite a bit in February. There is a dry ski slope on the Great Orme and snowfall is sometimes thick enough on Snowdonia to provide a brief ski season.

Spring, from mid March till mid June, is cool but quite bright. The average high temperature gets up to 9°C in March, 11°C in April and 14°C in May. Night time temperatures remain very chilly. The sun comes out for longer and longer, jumping to five hours per day in April and six in May. Rainfall drops slightly but it generally rains on around half of the days in each month. As it warms up people return to walking and climbing in the hills.
