I am not a weatherman but the saying here is that if there is a huge difference in the afternoon and night time temperature then you will get fog. This normally happens in December and Feb end. But Jan and most of Feb the temperature is more or less cold daytimes and night times. Hence no fog.

Maybe its a old wives tale but trust me it works. I have very rarely come across fog in Feb.

Yep I managed to book the ticket at 9pm last night. But the website is a lot smoother then it was last year.
