Why is Sydney not humid?
Sydney, the largest city in Australia, is known for its iconic landmarks, beautiful beaches, and vibrant culture. However, one thing that often surprises visitors is the lack of humidity in the city.
Despite being located in a subtropical climate zone, Sydney’s humidity levels are relatively low compared to other cities in the same region. In this article, we will explore the reasons behind Sydney’s low humidity and how it affects the city’s climate.
Before we dive into the reasons for Sydney’s low humidity, let’s first take a look at the city’s climate. Sydney has a temperate climate, which means that it experiences mild to warm summers and cool winters. The city’s average temperature ranges from 18°C (64°F) in winter to 26°C (79°F) in summer. Rainfall is spread fairly evenly throughout the year, with the wettest months being March and June.
The Influence of the Pacific Ocean
One of the main reasons for Sydney’s low humidity is the influence of the Pacific Ocean. The city is located on the east coast of Australia, and the prevailing winds blow from the ocean towards the land. As the air moves over the ocean, it picks up moisture, which can lead to high humidity levels in other coastal cities. However, in Sydney’s case, the ocean acts as a natural dehumidifier, reducing the amount of moisture in the air.
The Effect of the Mountains
Another factor that contributes to Sydney’s low humidity is the presence of the Blue Mountains to the west of the city. The mountains act as a barrier, preventing moist air from reaching the city. As a result, the air that reaches Sydney is drier and has lower humidity levels.
The Urban Heat Island Effect
While the ocean and the mountains play a significant role in reducing humidity levels in Sydney, the city’s urban heat island effect can have the opposite effect. The urban heat island effect is a phenomenon where urban areas experience higher temperatures than surrounding rural areas. This is due to the absorption and retention of heat by buildings and pavement. Higher temperatures can lead to increased humidity levels, especially during the summer months.

The Benefits of Low Humidity
Sydney’s low humidity levels have several benefits, especially for travelers. Low humidity levels make the city more comfortable to explore, even during the summer months. It also makes outdoor activities such as hiking, beach-going, and sightseeing more enjoyable.
