    Cornwall Weather for March 2023

    What's The Weather Like In Cornwall In March

    As the calendar moves from winter into spring, a slow warm up begins in and around Cornwall. While not as warm as other areas in and around Europe, there is a small tick upward in temperatures as they begin a slow march toward their warmest numbers of the year. March is also a wet month, but a significant drying trend is just around the corner beginning in April. This can be a great time to travel to the region as most tourists won't arrive until later in the year and there can be deals found for hotels and flights.

    Because this is still a rainy time of the year, it is important to examine an extended forecast before leaving home. Since over two-thirds of the month experiences rainy conditions, be sure to pack rain boots as well as other rain gear. 


    Rain is expected on an average of 22 days out of the month and some of it can be heavy at times. The heavier rain will be associated with thunderstorms produced by passing frontal systems. In all, 100mm of precipitation is expected over the course of the month.

    Sunshine Hours

    There is still very little sun during this time of the year and the region only experiences an average of 2 hours of sunshine per day.


    As a result, temperatures remain on the chilly side for one more month with an average daily temperature of just 7°C (45°F). Be sure to bundle up first thing in the morning with an average overnight low of 5°C (41°F). Temperatures will not be much warmer later in the day with highs of just 9°C (48°F).

    Sea Temperature

    It is also still too cold to enjoy a dip in the local waters, but it may be possible to stroll along the beach on a drier day. The water temperature during this time of the year is still a very chilly 9°C (48°F).
