Like much of the world, weather has become less predictable in Hong Kong in recent years. Historically, mid-December weather could be expected to be relatively low (~50%) humidity and in the 12-25℃ range during the day, with temperatures possibly falling below 10℃ at night on the highest peaks. In recent years, we have seen December days above 25℃ with high humidity, though that is not the most likely case scenario. Rain is infrequent in December, but when it does rain, temperatures on the mountains can be quite chilly. Thunder and lightning are rare. Please check weather forecast before the race and make sure to wear appropriate clothing to protect yourself.

近年香港的天氣與世界各地一樣，變幻莫測。以往，12月中都是比較乾爽，日間溫度在攝氏15至20度之間，晚間最低有機會在攝氏10度以下。最近幾年，我們嘗試過日間溫度在攝氏25度以上，加上頗高的濕度，十分反常。 下大雨的情況也有機會發生，如遇著這情況天氣會變得更寒冷，請選擇合適的裝備進行比賽。目前難以估計當時天氣，待較接近比賽時，我們會發電郵通知有關香港天氣情況。
與世界大部分地區一樣，香港的天氣近年來變得難以預測。從過往氣象紀錄，預計 12 月中旬的天氣濕度相對較低 （~50%），日間氣溫在 12-25°C 範圍內，但夜間溫度可能會降至 10°C 以下。近年來，我們看到 12 月的日子高於 25°C，濕度很高，儘管這不是最有可能的情況。12 月很少下雨，但下雨時，山上的氣溫可能會很冷。 雷電很少見。請在比賽前查看天氣預報，並確保穿著合適的衣服以保護自己。
