Does London Have High Humidity?

By Alice Nichols

London is one of the most popular cities in the world, known for its rich history, iconic landmarks, and beautiful architecture. However, one thing that often gets overlooked is the humidity levels in London.

So, does London have high humidity? Let’s take a closer look.

Understanding Humidity

Before we dive into whether London has high humidity or not, it’s important to understand what humidity actually is. Humidity refers to the amount of moisture present in the air. The more moisture there is, the higher the humidity level.

Humidity is typically measured using a device called a hygrometer, which measures the percentage of water vapor in the air. Humidity levels can range from very low (less than 20%) to very high (over 80%).

London’s Climate

London has a temperate maritime climate, which means that it experiences mild temperatures throughout the year and relatively high levels of precipitation. The city receives an average of 23 inches of rain per year, with most of it falling between October and January.

Summer Humidity Levels

During the summer months in London (June-August), humidity levels tend to be higher than other times of the year. This is because warm air holds more moisture than cold air, and during summer months temperatures can reach up to 25°C (77°F).

According to data from Weather Atlas, average humidity levels in London during summer range from around 65% to 75%. While this may seem quite high, it’s not considered overly oppressive or uncomfortable.

Winter Humidity Levels

During winter months (December-February), temperatures in London are much cooler and therefore humidity levels tend to be lower. Average humidity levels during winter range from around 70% to 80%, again according to data from Weather Atlas.

It’s worth noting that while London’s humidity levels may seem high compared to other parts of the UK, they are relatively low compared to other major cities around the world.

Conclusion

So, does London have high humidity? While humidity levels in London can be higher during summer months, overall they are not considered particularly high. However, it’s important to note that everyone’s tolerance for humidity is different, and what one person considers comfortable another may find uncomfortable.

Whether you’re planning a visit to London or you’re a resident curious about your city’s climate, understanding humidity levels can help you prepare and stay comfortable. With its mild temperatures and moderate humidity levels, London is a city that can be enjoyed year-round.
