Cairns is waking to a warm, humid morning typical of the wet season, with the live forecast above showing a high chance of showers and storms building through the afternoon as the monsoon trough lingers over the far north.
What is driving Cairns weather this week?
The monsoon trough remains active across the tropical coast, pulling in deep tropical moisture that fuels daily storms and heavy rainfall. Cairns sits on the edge of a broad low-pressure system, so while mornings can be partly sunny, the heat and humidity will trigger afternoon downpours. The live forecast above captures the unsettled pattern that defines this time of year.
How does the wet season shape Cairns weather year round?
Cairns weather year round splits into two distinct halves. The wet season, from November to April, brings high humidity, frequent storms and the highest rainfall totals, often exceeding 400mm per month. The dry season, May to October, offers stable blue skies, lower humidity and comfortable daytime temperatures around 26°C, making it the most popular window for visitors.
Is it safe to swim at Cairns beaches today?
Stingers and crocodile warnings are active year-round. Check the live forecast above for storm activity; rain can wash debris and increase currents. Always swim between the flags at patrolled beaches.
When is the best time for a clear view of the Great Barrier Reef?
The dry season, June to October, offers the calmest seas and lowest rainfall. The live forecast above shows cloud cover now, but winter mornings often deliver glassy conditions ideal for reef tours.
Does the Cairns weather radar show cyclones?
The local radar picks up heavy rain bands, but for cyclone tracking you need the Bureau’s broader satellite. Cairns weather warning today is for storms, not cyclones, though the season runs until April.
