Milford Sound Weather
Expect rain, and lots of It
Milford Sound is one of the wettest inhabited places on Earth. It receives over 6,000 mm of rain each year — sometimes more — spread across around 182 days annually. That means rain isn’t the exception; it’s the rule.
But here’s the secret: rain makes Milford Sound more spectacular. After just a few hours of rainfall, hundreds of waterfalls appear, tumbling down sheer cliffs in silver ribbons. The more it rains, the more dramatic the landscape becomes. Stirring, moody, and alive with movement — this is when Milford Sound really shows off.
The sun still shines
Clear, blue-sky days do happen — and when they do, Milford Sound sparkles. The water glows deep green and blue, the cliffs stand sharp and defined, and the tops of the peaks (including iconic Mitre Peak) are often visible in full. It’s a different kind of beauty, but just as memorable.
These days are also ideal for scenic flights and kayaking, when calm conditions let you explore the fiord in total stillness.
Four seasons in a day
It’s not unusual to experience sunshine, heavy rain, gusty wind, and a rainbow — all within an hour. Milford Sound weather can change quickly and dramatically due to its location and geography.
Summer (Dec–Feb): Warm, humid days with frequent afternoon showers. Daytime highs around 18–25°C, but always bring a waterproof layer.
Autumn (Mar–May): Often clear and crisp, with cooler mornings and stunning late light. A great time to hike or take a cruise.
Winter (Jun–Aug): Cold and dramatic, with snow-dusted peaks and misty mornings. Temperatures can dip to 0°C overnight. Fewer crowds, more atmosphere.
Spring (Sep–Nov): Waterfalls run strong with snowmelt. A mix of sunshine and showers, with temperatures slowly warming up.

What to Pack
Layers are key. Regardless of the season, visitors should come prepared for cool temperatures, strong sun, and sudden downpours. Essentials include:
A high-quality rain jacket
Warm layers, even in summer
Quick-drying clothes
Good walking shoes or hiking boots
A beanie and gloves (yes, even in summer if you’re hiking or boating)
Insect repellent — especially in warmer months
Why Staying Overnight Matters
The weather is one of the best reasons to stay in Milford Sound, not just visit for the day. With more time, you get to experience the full range of conditions - misty mornings, moody evenings, bursts of golden light between showers.
But perhaps the most rewarding moments are the ones most day visitors never get to see: sunrise and sunset. When the sky catches fire behind the peaks, or soft morning light spills into the fiord through the mist, Milford Sound becomes otherworldly. These are the moments that linger long after the trip ends - and they only happen if you’re here to see them.
When the crowds leave and the weather changes by the hour, Milford Sound becomes something truly special. Whether you catch a clear sunrise, a fiery sunset, or fall asleep to the sound of rain on the roof, the atmosphere is always unforgettable.
