1. 香港幾時打風？點解年年都要掛風球？ 地理、命名與天氣 · 答案見 /questions#typhoon-season

   熱帶氣旋可以全年影響香港，但最集中在夏末秋初；實際影響以天文台發出的熱帶氣旋警告信號為準，信號分為1、3、8、9、10號。

   Tropical cyclones can affect Hong Kong at any time of year but cluster in late summer and early autumn. In practice, what matters is the Observatory’s warning signal — 1, 3, 8, 9 or 10.

2. 香港點解咁熱、咁濕、成日落雨？ 地理、命名與天氣 · 答案見 /questions#why-is-hong-kong-hot

   香港屬副熱帶氣候：全年平均氣溫約23.5°C，平均全年雨量約2,431.2毫米，夏季受海洋、季候風和高密度城市建築三重影響，所以悶熱、多雨、雨勢集中。

   Hong Kong has a subtropical climate: the annual mean temperature is about 23.5°C and annual rainfall about 2,431.2 mm. Summer heat comes from the ocean, the monsoon and the density of the built city.

3. 香港有冇夏令時間？ 人口、語文與自然 · 答案見 /questions#daylight-saving-time

   冇。香港現時全年採用香港時間（UTC+8），不實施夏令時間；歷史上曾在二十世紀中至1970年代末多次實施，之後取消。

   No. Hong Kong uses Hong Kong Time (UTC+8) all year with no daylight saving. Summer time was observed intermittently from the mid-twentieth century until the late 1970s and then discontinued.

4. 「香港腳」點解叫香港腳？ 文化、飲食與日常 · 答案見 /questions#hong-kong-foot

   「香港腳」是足癬（真菌感染）的俗稱。名稱源自十九世紀至二十世紀初，來港的英國士兵與僑民在潮濕悶熱環境下普遍患上足癬，回國後同類症狀被稱為「香港腳」；與香港的氣候及當年駐軍生活條件有關，唔係香港獨有病症。

   “Hong Kong foot” is the Chinese colloquial name for athlete’s foot (tinea pedis). It dates to the nineteenth and early twentieth centuries, when British troops and residents in Hong Kong’s hot, humid climate commonly developed the infection — the name followed them home. The condition is not unique to Hong Kong.

5. 香港天氣最熱係幾多度？歷年最熱年份係邊年？ 地理、命名與天氣 · 答案見 /questions#hong-kong-hottest-year-weather

   香港天文台的 1885 年起逐日序列顯示，近十年酷熱日數與平均氣溫顯著上升。2023 年平均氣溫 24.6°C 為歷年最高之一；單日最高氣溫錄得 36.1°C 或以上的高溫，天文台均以酷熱天氣警告提醒市民。

   The Hong Kong Observatory daily series since 1885 shows a clear rise in both mean temperature and hot nights in recent decades. The annual mean of 24.6°C in 2023 was among the warmest on record; very hot days reach 36.1°C or above and trigger the Very Hot Weather Warning.

6. 香港一年幾時最多雨？降雨量同颱風點樣由天文台統計？ 地理、命名與天氣 · 答案見 /questions#monthly-weather-rainfall-pattern

   香港降雨主要集中於春末至初夏同夏季，受季候風同颱風影響。香港天文台每年公布月雨量、年雨量、颱風路徑同熱帶氣旋統計，全部有明確統計時期。

   Hong Kong rainfall concentrates in late spring, early summer and the summer months under the monsoon and typhoon seasons. The Observatory publishes monthly and annual rainfall, typhoon tracks and tropical-cyclone statistics with explicit reporting periods.

7. 香港最熱／最凍試過幾多度？有冇試過40度？ 地理、命名與天氣 · 答案見 /questions#hong-kong-temperature-records

   市區天文台最高氣溫紀錄係 2022 年 7 月 22 日嘅 39.0°C，最近但尚未觸及 40 度；最低氣溫紀錄係 1957 年 1 月 18 日嘅 0.0°C。新界高地同郊區分站氣溫或更低，屬分站紀錄，唔同市區天文台數字。

   The Observatory’s record maximum is 39.0°C on 22 July 2022 — the hottest yet, but still below 40°C; the record minimum is 0.0°C on 18 January 1957. Countryside and highland sub-stations can read lower, which are separate station records, not the urban Observatory figure.

8. 香港幾時係雨季？ 地理、命名與天氣 · 答案見 /questions#hong-kong-rainy-season

   香港全年平均雨量約2,431毫米（1991–2020年正常值），雨季集中在五至九月，以七月雨量最多；冬季（十二至二月）較乾燥。天文台的颱風季同西南季候風喺夏日帶來暴雨。

   Hong Kong’s mean annual rainfall is about 2,431 mm (1991–2020 normal), concentrated from May to September with July the wettest month; winter (December–February) is drier. Summer typhoons and the south-west monsoon bring heavy rain.

9. 點解香港咁焗／咁潮濕？ 地理、命名與天氣 · 答案見 /questions#why-hong-kong-humid

   香港屬亞熱帶季風氣候，初夏至夏末受西南季候風影響，連埋高溫同大雨，令濕度長期偏高。全年平均氣溫約23.5°C（1991–2020年正常值），夏季尤其潮濕悶熱。

   Hong Kong has a sub-tropical monsoon climate; from early to late summer the south-west monsoon brings high temperature, heavy rain and persistently high humidity. The annual mean temperature is about 23.5°C (1991–2020 normal), so muggy heat is common in summer.
