In Nepal this Monsoon is started very late and monsoon stops also very late. Trekkers are all targeted middle of October because last year weather is very good. This is Annapurna base camp trekking is very busy. Because of Lukla flight cancellation. This year middle of the October also raining like monsoon. Lukla weather is very worst. Almost trekking company changes plan. The send tourist Annapurna base camp instead of Everest base camp. Pleas see this picture I think you will feel it.
