Generally, we're unable to provide answers via our support desk to questions regarding specific places or locations, e.g. when is the best time to shoot X, or when is the best time to visit Y.
But, that's exactly what The Photographer's Ephemeris is for!
So, please go ahead and use the app to research your location and the light conditions you would like to photograph. Remember: what constitutes 'best' will vary based on the location, type of shot you're looking for, your photographic style, equipment etc.
