In Falmouth, precipitation falls quite regularly throughout the year, and there is no distinct dry season. The weather is rather characterized by frequent but not overly heavy rains, especially if judged by the ratio of rainy days to the total volume of rainfall.

The greatest amount of precipitation usually falls during the autumn-winter period. Thus, October and November are the wettest months in terms of rainfall volume, averaging 4 mm in each. December stands out with the highest number of rainy days — about 18, followed by March and November, which account for approximately 17 days with precipitation each.

This indicates that Falmouth is characterized by frequent but light rains or drizzle. Given the mild temperatures throughout the year, precipitation predominantly falls as rain.

When planning a trip to Falmouth, it is important to consider its maritime climate with moderate temperatures and a high probability of precipitation throughout the year. The key principle when packing your suitcase should be layering. An indispensable item will be a waterproof and windproof jacket or raincoat, as rains here are a frequent occurrence, especially from October to March, when the number of rainy days reaches 15-18 per month. Don't forget a sturdy umbrella, although in windy weather, a good jacket with a hood may prove more practical.

In the cold season, which lasts roughly from October to March, be prepared for low temperatures. Especially in the period from December to February, when the average temperature is around 7-9°C, you will need warm sweaters, fleece tops, perhaps thermal underwear, as well as a scarf, hat, and gloves. In October, November, and March, it is usually slightly warmer (average temperatures around 8.5-13°C), but warm layered clothing will still be relevant. In the warmer months, from May to September, when daytime temperatures are most often in the 15-19°C range, t-shirts and light trousers or shorts will suffice. However, even in summer, evenings can be cool, so a light jacket or cardigan will be very useful. Considering that maximum temperatures rarely rise above 19-20°C, you should not rely exclusively on summer clothes.

Regardless of the season, comfortable waterproof footwear for walking is an absolute necessity, as you will surely want to explore the picturesque surroundings of Falmouth. Even in the summer months, despite the lower amount of rainfall in millimeters, there are still quite a few rainy days (12-13 days). On sunny days, especially in summer, do not forget sunscreen and headwear, as the British sun can be deceptive.
