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 I it starts — in Holland at least — on either the 22nd or 23rd of September. In 2013, autumn officially begins on September 22.
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.
Saturday (24) A sunny day — partially cloudy until about 4 pm, and abundantly sunny from then until about 7:30 pm. Today’s high temperature of 23° Celsius (73.4° Fahrenheit) will occur around 4 pm, and it will remain pleasantly warm until well into the early evening.
Sunrday (25) Sunny until about 2 pm, after which clouds will move in. Possibly some scattered, light rain (or drizzle) in the late afternoon or early evening. It won’t get warmer than 22° Celsius (71.6° Fahrenheit) at around 2 pm.
Monday (26) More clouds than sun, along with a mid-afternoon high of around 19° Celsius (66.2° Fahrenheit).
Tuesday (27) Depending on which weather forecast service you believe, it will either by dry and quite sunny all day — with a late afternoon high temperature of 20° Celsius (68° Fahrenheit), OR very cloudy, with some light rain or drizzle in the afternoon, OR cloudy but dry with a sunny period from the late morning through the late afternoon. Your guess is as good as ours. Just visit this page on the day itself to look at the weather graphic.
Wednesday (28) Cloudy with some partial sun, and an early afternoon high of 21° Celsius (69.8° Fahrenheit). Possibly a spot of light rain around 8 pm.
Thursday (29) Mostly overcast, but dry. It will be 19° Celsius (66.2° Fahrenheit) pretty much throughout the day, but the feels-like temperature will be two or three degrees lower.
Friday (30) Sunny in the early morning and late afternoon. Sunny intervals the rest of the time, with a possible light shower in the late morning. Count on a high temperature of 19° Celsius (66.2° Fahrenheit) around 2 pm.
Long-term forecast: Saturday, October 1 through Saturday, October 8 Initially rather changeable (read: expect scattered rain showers from time to time), along with mid-day temperatures around those normal for the time of year.

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…
