Cornwall Weather & Falmouth Weather: What to Expect Year-Round

Introduction

If you’re planning a trip to Cornwall, one of the first things you’ll want to check is the Cornwall weather forecast. With its dramatic coastline, golden beaches, and lush countryside, Cornwall’s climate plays a key role in shaping the visitor experience. But what about Falmouth weather specifically? As one of Cornwall’s most popular coastal destinations, Falmouth benefits from a milder, maritime climate, making it an appealing year-round destination.

So, whether you’re wondering “What is Cornwall’s weather like in summer?” or “Does Falmouth get snow in winter?”, this guide will help you understand what to expect and how to plan your trip accordingly.


Cornwall’s Climate: A Quick Overview

Cornwall, located in Southwest England, enjoys a temperate oceanic climate, meaning it experiences mild winters and warm summers. Thanks to its location jutting out into the Atlantic, the county often benefits from milder conditions than the rest of the UK.

Key Features of Cornwall’s Weather:

  • Mild Winters: Rarely dropping below freezing.
  • Moderate Summers: Warm but rarely too hot.
  • Coastal Influence: Higher humidity, frequent sea breezes.
  • Changeable Conditions: Sun, rain, and mist can all appear in a single day!

  • Winter (Dec–Feb): 4°C – 9°C
  • Spring (Mar–May): 9°C – 15°C
  • Summer (Jun–Aug): 15°C – 20°C
  • Autumn (Sep–Nov): 11°C – 17°C

Falmouth Weather: A Microclimate Worth Noting

While Cornwall weather is generally mild, Falmouth weather has its own microclimate, thanks to its position on the south coast. Sheltered from the harsher Atlantic winds that batter the north coast, Falmouth enjoys some of the sunniest weather in Cornwall.

How Falmouth Weather Compares to the Rest of Cornwall:

  • Warmer Winter Nights: The sea retains heat, keeping temperatures slightly higher.
  • Less Rain than the North Coast: Coastal showers pass quickly, with more sunshine overall.
  • Cooler Summer Afternoons: Thanks to sea breezes, Falmouth rarely experiences extreme heatwaves.
