The climate of Saint Austell can be described as mild and temperate maritime, which is typical for the south-west coast of the United Kingdom. Thanks to the influence of the ocean, extreme temperature fluctuations rarely happen here: winters pass without severe frosts, and summer delights with comfortable warmth without stifling heat. This makes the town a pleasant destination to visit, where the weather is rarely too harsh.

Precipitation falls quite regularly throughout the year, so an umbrella or raincoat will be important companions on your journey. The highest number of rainy days occurs during the autumn-winter period, peaking in December. Summer, conversely, brings more dry days; however, even in the warmest months, such as July and August, short-term showers are possible, maintaining the famous lush greenery of the local landscapes.

The most favourable time for a visit is considered to be the period from late spring to early autumn. In July and August, the air warms up on average to a comfortable +16...+19°C, which is ideal for walks and excursions. The temperature in Saint Austell remains quite stable, without sharp spikes, allowing tourists to easily plan their wardrobe, giving preference to layered clothing.

Typical British weather is characteristic of the climate in Saint Austell, with frequent but, as a rule, not overly intense precipitation. Rains occur here quite regularly throughout the year, so an umbrella or raincoat will become your faithful companions in any season. Thanks to mild temperatures, even in winter, precipitation falls primarily in the form of rain, and snowfall happens extremely rarely.

The wettest period is considered to be winter and the beginning of spring. The rainiest month, according to statistics, is December, when precipitation is recorded on average 19 days per month. A high probability of rain also persists in March (about 18 days with precipitation) and in the late autumn months, for example, in October and November, when the sky is often overcast with clouds.

A relatively dry season arrives in summer, however, one cannot completely rule out rain even at this time. The "driest" month can be called July, when the number of rainy days decreases to 12. In the period from April to August, rains occur slightly less often, approximately 13 days per month, making this time the most favourable for walks and sightseeing.

Setting off for Saint Austell, it is important to remember the mild but changeable maritime climate of Cornwall. It is rarely extremely hot or cold here, however, high humidity and wind from the Atlantic require a special approach to your wardrobe. The main principle of packing is layering: a combination of a t-shirt, a fleece jumper, and a light jacket will allow you to feel comfortable during any change in weather, which can happen several times a day.

Since precipitation falls here regularly throughout the year (from 12 to 19 rainy days per month), definitely take a high-quality waterproof raincoat or a windbreaker with a hood. An umbrella may not always be practical due to gusty winds, so reliable water-repellent outerwear will be your best solution. Also critically important are comfortable, preferably waterproof, flat shoes: you will have to walk a lot along hilly streets and the famous gardens of the region.

In summer, when the temperature holds around a comfortable 16–19°C, light items made of natural fabrics will come in handy, but do not forget a warm jumper for cool evenings and sunscreen. In winter, despite the absence of strong frosts (average temperature around 7–8°C), the dampness makes the cold feel sharper, so an insulated jacket, scarf, and gloves will be indispensable for comfortable walks.
