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.
