With an annual average high of 23.6°C and mild lows hovering around 17°C, Byron’s got that perfect balance of sunny beach days, refreshing ocean breezes, and crisp winter mornings made for coffee runs.

Mid-September through early May, when the water’s warm, skies are clear, and the coast really shines.

Summer in Byron Bay brings hot, beach-perfect days averaging 27°C and balmy lows around 20°C. The ocean is at its warmest, so it’s prime time for endless swims, surfing sessions, and long days on the sand. Afternoon showers are common, cooling things down and keeping the hinterland lush.

This is also Byron’s busiest season with school holidays in full swing — so expect buzzing beaches, packed markets, and plenty of live music in town. Don’t forget the sunscreen, a hat, and maybe a post-beach smoothie bowl to keep cool.

Autumn serves up warm, comfortable weather in Byron Bay, with highs in the mid-20s and lows of around 15°C. The ocean stays swimmable in the earlier months, perfect for squeezing in a few last salty dips before winter. With the end of daylight savings, mornings feel warmer and the crowds thin out as school resumes, making it easier to snag a quiet spot on the beach.

Note that Autumn has the highest amounts of rainfall in the year, with March bringing in an average of 202.9 mm of rain.

If you're planning a trip for the Easter Long Weekend, the Byron Bay Bluesfest is a must; it features world-class live music, over 100 food and market stalls and plenty of family-friendly entertainment.

July is the chilliest month with average highs of 19°C and lows of 11°C. However, the mild weather is still great for coastal walks, lighthouse strolls, and whale watching from the headlands. Pack a hoodie or light jacket for evenings and enjoy Byron without the summer crowds. It's a quieter, more relaxed vibe that’s just as special.

For the creatives out there, the Byron Writers Festival happens every August.

Spring in Byron Bay (Sep–Nov)

It also coincides with Byron's Sample Food Festival. Talk about foodie heaven! October, on the other hand, will bless your ears with the Nimbin Roots Festival. If you’re planning a Byron Bay holiday, spring is a guaranteed good time; you’ll get that summer feeling without the peak-season hustle.
