Gulmarrad’s subtropical climate means mild winters and warm, humid summers, with the live forecast above showing today’s conditions. The best months to visit are September–November and March–May, when temperatures are pleasant and rainfall is lower, avoiding the peak summer humidity.
What is the weather like in Gulmarrad year-round?
Gulmarrad, in northern NSW, sits near the coast between Grafton and Yamba, so its weather is shaped by sea breezes and inland valleys. Summer (December–February) averages 19–29°C with frequent showers and thunderstorms. Winter (June–August) is mild at 8–20°C, with clear, crisp days. Spring and autumn offer the most comfortable conditions for outdoor activities, with lower humidity and stable skies.
When should I visit, and what should I pack?
Plan your trip outside the NSW school holidays (April, July, September–October) to avoid crowds and higher accommodation prices. For a winter escape, June–August brings sunny days perfect for exploring the Clarence Valley. Pack light layers, a rain jacket for summer storms, and sunscreen year-round. The nearby Brisbane weather and Sydney weather patterns often influence regional conditions, so check those for broader travel plans.
Is Gulmarrad weather similar to Yamba weather?
Yes, both share a coastal subtropical climate, but Gulmarrad is slightly inland, so it can be a degree or two warmer in summer and cooler overnight. Yamba weather is more moderated by the ocean breeze.
Does Gulmarrad get severe storms like Grafton weather?
Gulmarrad can experience summer thunderstorms and occasional east coast lows, similar to Grafton weather. Check the Severe Weather Warning page before travelling in wet season.
What is the UV index like in Gulmarrad?
UV levels are high from October to March, often reaching extreme (11+) in summer. Wear SPF50+ sunscreen, a hat, and sunglasses, even on overcast days near the coast.
