The climate in Blackburn, like much of the United Kingdom, can be described as temperate maritime. This means there are no extreme temperatures—neither sweltering heat in summer nor severe frosts in winter. The weather is quite changeable, with rainfall distributed more or less evenly throughout the year.

Blackburn experiences four distinct seasons. Winters (December–February) are cool, with average temperatures around 4–5°C and frequent rain. Spring (March–May) brings gradual warming, with average temperatures rising to 8–11°C; rainfall decreases slightly, especially in April and May. Summer (June–August) is the warmest time of year, though not hot, with average temperatures around 14–15°C and highs rarely exceeding 19°C. Autumn (September–November) is characterized by a gradual drop in temperature and an increase in rainy days, particularly in October.

One of the key features of the weather in Blackburn is high humidity and a significant number of rainy days throughout the year. Even in the summer months, you should be prepared for rain, as the number of "wet" days remains high (16–20 days per month). The highest rainfall and number of rainy days occur in July, August, and October. Therefore, when planning your trip, be sure to bring an umbrella and waterproof clothing, regardless of the season.

Blackburn has a temperate climate with distinct seasons but no extreme temperatures. The annual temperature cycle shows that the coldest month is typically January, with an average temperature of about 4.2°C, followed by December and February with averages around 5.2°C. The warmest period is July, when the average temperature reaches 15.4°C, and August with an average of 15.3°C. Overall, the climate can be described as mild, with cool winters and pleasantly warm, comfortable summers.

The summer months in Blackburn, such as June, July, and August, offer pleasantly warm weather. Average maximum temperatures in July and August reach 18.3–18.7°C, which is ideal for outdoor activities and sightseeing without the sweltering heat. At night, temperatures drop to a comfortable 10–12°C. Daily temperature fluctuations in summer can be noticeable, with a difference of about 6–7°C between the daytime high and nighttime low, especially in June. This means evenings can be quite brisk.

Winter in Blackburn is characterized as cool but without severe frosts. In January, the coldest month, the average minimum temperature is about 2.1°C and the average maximum is 6.4°C. Similar conditions are seen in December and February, when daytime temperatures rarely rise above 7–8°C, and nighttime temperatures can approach 2–3°C. The difference between daytime and nighttime temperatures in winter is usually smaller than in summer, at around 4–5°C, creating a more even and consistently cool feel.

In Blackburn, precipitation is distributed fairly evenly throughout the year, and there are no distinct dry or rainy seasons. A characteristic feature of the climate is frequent but usually very light drizzle or light rain. This is evidenced by the high number of days with precipitation (from 13 to 20 per month) despite a relatively small total monthly volume, which ranges from 2 to 5 mm.

The highest rainfall, around 5 mm, typically occurs in October, which is also one of the months with the highest number of wet days—averaging 20 days. A similar situation regarding the number of rainy days is seen in August (also 20 days), although the total rainfall there is about 4 mm. Relatively "drier" months include April and May: during this period, only 2 mm of rain falls, and the number of rainy days drops to 13–14, which still means nearly half the month has some form of precipitation.

Precipitation in Blackburn mostly falls as rain. Given the low average monthly temperatures in winter, such as January (average minimum 2.1°C), February (2.7°C), and December (3.2°C), when the thermometer can approach or drop below freezing, snow is possible. In the summer months, such as July (19 rainy days) and August (20 rainy days), rain is also frequent, but like the rest of the year, it is mostly light.

When planning a trip to Blackburn, it's important to consider its changeable weather, typical of the UK. Regardless of the time of year, being prepared for rain is key. The average number of rainy days per month is quite high (from 13 to 20), so a waterproof jacket or raincoat and a sturdy umbrella are suitcase essentials. Comfortable, ideally waterproof walking shoes are also highly recommended, as you will likely be getting around the city in wet weather. Dressing in layers is your best friend in Blackburn, allowing you to easily adapt to temperature changes throughout the day.

During the summer months (June–August), when average temperatures hover around 14–15°C, you'll need light clothing such as T-shirts, long- and short-sleeved shirts, trousers, or jeans. However, don't forget to pack a light sweater or fleece for evening strolls or cooler days, along with the aforementioned rain protection. In colder periods, from late autumn to early spring (October–April), when temperatures can drop to 2–8°C, warmer items are necessary. Pack warm sweaters, fleece jackets, heavy outerwear (a coat or jacket), as well as a hat, scarf, and gloves, especially for the winter months (December–February). Even in the warmest months, rainfall remains significant, so a raincoat is useful all year round.
