What is the difference between the wet and dry season in Cairns?
The dry season (May-October) is the ideal time for outdoor activities. If you are checking a cairns weather forecast 7 days or a weather in cairns 10 days forecast during winter, you will see mostly sunny days and low humidity. Clear skies are typical for the cairns weather tomorrow forecast during this period. The wet season (November-April) brings daily afternoon storms and high humidity. It is also stinger season, so swimming on the beaches is not recommended.
How do I check the latest radar and warnings?
The cairns weather radar loop is the best tool for tracking local rainfall and storms. The Bureau issues cairns weather warning today alerts for cyclones, severe thunderstorms, and heavy rainfall events. Always check the live radar before heading out for the day.
Is it safe to swim year round in Cairns?
No. Marine stingers are present in the water from November to April. The safest swimming conditions are in the dry season (May-October) when stingers are not active and beaches are patrolled.
Does it rain every day in the wet season?
Generally, yes, but it usually comes as a short tropical downpour followed by sunshine. A cairns weather forecast 14 days during summer often shows daily rain icons, but the total accumulation varies between showers.
Does it get cold in Cairns in winter?
Nights and early mornings can drop to around 17°C in July. It feels cooler with the breeze. It is advisable to pack a light jacket for evenings, but winter days remain warm and sunny.
