Summer is pleasant. However, winter is quite cold. Best time to visit the park is September to November and March to June. Average annual temperature in the last 10 years is little over 11°C. Monthly maximum and minimum mean temperature is 27°C and 4°C in June and December respectively. From December to February, the temperature drops down below to freezing point, and occasional heavy snowfall accumulates up to 3-4 feet high. Pretty rain fall occurs in June to August and the park looks more beautiful in this season due to flowering plants. April normally sees the start of the warmer season which steadily increases to a pleasant temperature until September.
