What's The Weather Like In Cornwall In January

While January is the heart of winter in Cornwall, temperatures rarely get below the freezing mark. However, that doesn't mean that visitors can leave the jackets at home as the wind blowing off the sea can make it feel much colder than the actual temperature. Clouds and rain are likely during this time of the year, so it is wise to check an extended forecast before leaving home to make sure the right clothing is packed.


This is also one of the wettest times of year with an average of 110mm of precipitation. Because temperatures are likely to stay above freezing, there is little chance of seeing the rain turn into snow. However, the rain falls over an average of 25 days out of the month. As a result, it is a good idea to pack plenty of rain gear and plan for some indoor activities. Much of this precipitation comes from showers and thunderstorms associated with frontal systems moving from the west to the east across the Atlantic Ocean.


With the rain and an 80 percent chance of experiencing a windy day, temperatures don't get too much of a chance to warm up throughout the daytime hours. In fact, the average daily high temperature only reaches 8°C (46°F). Meanwhile, temperatures will bottom out with an average overnight low of 4°C (39°F). Overall, the average daily temperature is a cool 6°C (43°F).

Sunshine Hours

Additionally, there is not much of a chance of the sun helping to warm things up as the area only experiences an average of 2 hours of sunshine per day.

Sea Temperature

Meanwhile, this is not the best time of the year to visit the local beaches as water temperatures are too cold to enjoy. The average surface temperature for this time of the year is a chilly 10°C (50°F).
