People are likely to look at your invitation and make a quick first impression -- you want that first impression to be informative and fun. 1  If your party doesn't have a theme, have the invitation mirror the formality of the party.
September weather in Amsterdam. As mentioned, the weather in Amsterdam tends to be quite mild all summer, and by September itâs usually on the cool side. The highest temperature ever recorded in September is 83Â°F/28Â°C and the daily peak will almost always be fairly close to the 64Â°F/17Â°C? average.
Best time to visit. Thereâs never a promise of good weather in Amsterdam, but you can expect milder temperatures and longer days between April and September. April is especially lovely -- those famous tulips will be blooming, and you can celebrate Hollandâs biggest holiday of the year, Kingâs Day.
