The best time to go to Cadgwith is during the late spring (May to early June) and early autumn (September to early October) when the weather is pleasant and the crowds are smaller.During late spring, the Cornish countryside is in full bloom, making for beautiful coastal walks and vibrant scenery. The days are long, and the temperatures are mild, typically ranging from 12°C to 18°C. This period is ideal for couples who enjoy exploring the South West Coast Path, with its stunning views of the Lizard Peninsula, or simply relaxing by the harbour.Early autumn offers similar advantages with comfortable temperatures, usually between 10°C and 16°C, and fewer visitors after the main summer holidays. The sea remains warm enough for some water activities.
