Most years, Amsterdam weather in September is nice — very nice, indeed.
And with the summer crowds gone, many think this is the best time to visit Amsterdam.

Usually Many Days of Summer-like Weather
Weather professionals say September 1 marks the metrological start of fall or autumn,
But for you and me, in the Netherlands fall starts on either the 22nd or 23rd of September. In 2021, autumn begins on September 22.
However, September often turns into somewhat of an extension of summer.
On average, the month enjoys 145 hours of sunshine. Of course, you cannot always expect summer-like weather. But on many days the temperature is rather mild.
Then again, hail- or thunderstorms are not unusual either. Yet, they usually occur at night.
To sum up: September sees smaller crowds, and usually has nice weather.
So 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…
