Conclusions

As you can see, there is not a perfect time (sunny, warm and dry months). You have to compromise according to your desires, if the rain bothers you more or if you are sensitive to cold.

Howerver, we can say that (from the worst to the best time of year):

February is excluded because the Inca Trail is closed for maintenance the whole month.
January and March are to avoid if possible because of the rain.
April, November and December are a good compromise between an almost warm temperature and a nice weather.
May and October offer a nice weather with fresh temperatures.
June, July, August and September are, to us, the best time of year because the weather is very nice even if nights are cool but there is almost no rain.
