Ik wist niet eens wat het was een Indian Summer, eerlijk gezegd 
Even gegoogeld en nu weet ik het wel dus..
The generally accepted use of the term is when the weather is sunny and clear, and above 21 °C (70 °F), and all of the leaves of the trees have turned but before the first snow has fallen; a period normally associated with mid-October to late-November in the northern states of the U.S. Traditionally, Indian summer can only be a true Indian summer after the first frost, generally a killing frost, of the season.
