Climate Overview

Hamilton Island enjoys a tropical climate, characterized by warm temperatures and relatively high humidity. The year is typically divided into two main seasons: the wet and the dry.

  • Summer (Wet Season) - December to March: During this time, the weather in Hamilton is hot and humid, with average temperature ranging from 25°C to 30°C (77°F to 86°F). The wet season brings heavy rainfall, often in the afternoon, along with the potential for tropical storms and cyclones. Despite the wet weather, the warm sea temperatures are perfect for beach lovers and those keen on exploring the lush, rain-soaked landscapes of the Whitsundays.

  • Winter (Dry Season) - April to November: The dry season is marked by cooler, more comfortable weather, with average temperature ranging between 18°C and 25°C (64°F to 77°F).

It also coincides with the peak tourism season, especially between June and August when holidaymakers flock to the Whitsundays for their dream island holiday.

Best Time to Visit

The best time to visit Hamilton Island is during the dry season, from April to November, when the weather is at its finest. With lower humidity and less rain, this period is perfect for outdoor activities such as snorkeling, diving, sailing, and exploring the Great Barrier Reef.

Sun, Humidity, Cyclones, and Stingers: What to Expect on Hamilton Island

Hamilton Island, like much of Queensland, experiences significant exposure to sunlight year-round, with a particularly high UV index during the summer months. This intense sun exposure requires visitors to take proper precautions, such as wearing sunscreen, hats, and protective clothing to avoid sunburn and long-term skin damage. The sun is most intense between 10 a.m. and 2 p.m., making this period crucial for sun protection.

The humidity on Hamilton Island peaks during the wet season (December to March), contributing to a hot, sticky atmosphere. High humidity can make outdoor activities more strenuous and affect comfort levels, especially during the hottest part of the day. Staying hydrated and seeking shade or air-conditioned areas is essential during this period.

Hamilton Island is also located within the cyclone belt, with cyclone season running from November to April. Although cyclones are not frequent, the island can experience strong winds and heavy rain during this time. It's important to stay updated on weather forecasts and follow any safety advice provided by local authorities.

During the warmer months, particularly from November to May, marine stingers like box jellyfish and Irukandji are present in the surrounding waters. These stingers can cause painful and potentially dangerous stings, making it necessary to wear protective stinger suits when swimming or snorkeling. Beaches are often patrolled, and stinger nets may be used to create safe swimming areas.


Hamilton Island is an all-year-round destination that caters to every type of traveller, from those in search of a relaxing beach holiday to adventurers exploring the Great Barrier Reef. Whether you're interested in the best weather Hamilton has to offer or the island wildlife, the Whitsundays, and particularly Hamilton Island, deliver a memorable and luxurious tropical experience in Australia.
