The highest number of rainy days usually falls in March, October, and December. According to the provided data, the total monthly rainfall is low (2-3 mm), which may indicate frequent but predominantly light rain or drizzle, typical of British weather. This creates a typically damp atmosphere, especially in the autumn-winter period, so light waterproof clothing may be useful at any time of the year.

In Swindon, precipitation falls throughout the year, yet the total amount remains surprisingly low. Only 2-3 mm of precipitation is recorded monthly. This suggests that intense downpours are unlikely; rather, it is a matter of frequent but very light rain or drizzle. A clearly defined rainy season with heavy rainfall is not observed in Swindon.

Despite the small total amount, precipitation in Swindon is a quite frequent phenomenon. The number of rainy days per month ranges from 11 to 16. The highest number of days with precipitation occurs in March (on average 16 days), followed by December (15 days) and October (14 days). Thus, although the total rainfall in these months is not significantly higher (2-3 mm), wet weather is more likely. The fewest number of rainy days (about 11) is characteristic of January, February, April, and June.

Given the nature of precipitation – frequent but very insignificant in volume – travellers to Swindon should carry light rain protection. Although the months with the most precipitation (3 mm) are September, October, and December, the difference with other months (2 mm) is minimal. In the winter months, with temperatures close to freezing, the probability of mixed precipitation or very light snow cannot be completely ruled out, but the main weather character, according to the provided data, remains predominantly rainy and drizzly.

When planning a trip to Swindon, it is important to consider the changeable weather typical of the UK and frequent precipitation. Regardless of the season, the key is layering your clothing. A light waterproof and windproof jacket or raincoat, as well as a compact umbrella, will become your faithful companions, as even with a small total amount of rainfall (2-3 mm per month), rainy days are not uncommon here (11-16 days per month). Comfortable, preferably waterproof walking shoes are also a must to comfortably explore the city.

In the colder months, roughly from October to April, when the average temperature ranges from 4.6°C to 11.6°C, it is worth bringing warmer clothing. Sweaters, fleece tops, warm trousers, as well as a hat, scarf, and gloves will help keep you warm, especially considering the potential wind. In the coldest months, January and February, average temperatures stay around 4-6°C, so do not forget a warm coat or jacket.

In the warmer season, from May to September, the weather becomes more pleasant, with average temperatures from 12°C to 17°C, and maximums reaching 20-21°C in July and August. You will need T-shirts, light shirts, shorts, or skirts. However, even in summer, evenings can be cool, and sudden showers are still possible, so a light jumper or cardigan and that same waterproof jacket will not go amiss. Do not forget sunscreen and sunglasses for clear days, as the British sun can be deceptive.
