Most years, Amsterdam weather in September is nice — very nice, indeed.
Meteorologically, weather professionals consider September 1 to be the start of fall or autumn, but for you and me it starts — in Holland at least — on either the 22nd or 23rd of September. In 2017, autumn officially begins on September 21.
But in the Netherlands September tends to turn into somewhat of an extension of summer.
More often than not September — or at least the first three weeks of the month — has many days of summer-like weather with on average of 145 hours of sunshine for the whole month.
Then again, there may also be some hail- and thunder storms, especially in the coastal areas — and then particularly at night.
Still, whenever people ask us “what is the best time to visit Amsterdam?” we say “September.”

What to Wear in Amsterdam
Mind you, as always the weather in Amsterdam, as in the rest of Holland, can be rather changeable. That can make it hard to know what to pack.
Make sure you bring light rain gear, but by all means dress in layers. For one thing, the weather can (and often does) switch back and forth between bright and sunny one moment and brief showers (light or heavy) the next.
Usually the climate remains quite mild.
By the way, if you plan on bringing an umbrella make sure yours is windproof.
Some day someone (you?) will create a coffee table book with oodles of colorful pictures of discarded umbrellas along the streets, squares and canals of Amsterdam…
