Glad to hear from you. For the first day at begging, it will be warm during the day, with a temperature of about 15 to 20 degrees Celsius. And at the high point in Poon Hill (3,210 m), Ghorepani, Tadapani will be 10 to 15 degrees Celsius during daytime and night and early morning will be 0 to -10 degrees Celsius. But it will depend on the following day's weather conditions too. Normally, during this time weather is perfect. But the high Himalayan weather condition is unpredictable. It might be rain or snow sometimes. Let’s, think well then everything goes perfectly. Every tea house has a heater in the dining room, so you won’t feel cold while in the tea houses.
