Good question. You don’t get all that stunning rainforest and striking landscape without some weather and you may have heard that it rains from time to time in Milford too. Which is true, Milford Sound has an annual average rainfall of 6,813 mm. (268 inches)
Yes it rains sometimes but we’ve been going into Milford Sound since the 1970s and we’ve never had a bad day in there. When it rains, the waterfalls, streams and rivers are amazing - you can even see waterfalls tumbling off cliff tops only to be blown away into the wind! Milford Sound is an amazing place, no matter what the weather, even our Kiwi Guides who have been visiting for years tell every day at Milford is different.
