8月19日: 熱帶氣旋海高斯橫過南海北部,於登陸珠海前增強為颱風並吹襲珠江口,香港天文台於凌晨發出九號烈風或暴風風力增強信號,而澳門更一度發出十號風球,三條大橋均錄得持續颶風風速。

Aug 19: Tropical cyclone Higos traversed northern South China Sea. It intensified into a typhoon and struck the Pearl River Estuary before making landfall in Zhuhai.

All three major bridges there recorded sustained hurricane force winds.

111 78.72

12月31日: 一股強烈寒潮影響華南,香港天文台氣溫下降至全年最低的 8.1 度,是自 2018 年 2 月以來氣溫首次跌穿 10 度,而凌晨大帽山溫度曾下降至冰點以下。

Dec 31: A strong cold surge affected southern China. The mercury at the HK Observatory dipped to 8.1 degrees, the lowest this year.

89 63.12

10月13日: 熱帶氣旋浪卡橫過南海,雖然距港超過 400 公里,但由於有東北季候風疊加影響,天文台發出八號烈風或暴風信號,該信號於當天整段日間時間生效。

Oct 13: Tropical cyclone Nangka crossed the South China Sea. Although it maintained a distance of over 400 km from Hong Kong, the HK Observatory issued the #8 Gale or Storm Signal due to the combined effects of the storm and the northeast monsoon. The #8 Signal remained in force throughout daytime.

86 60.99

11月1日: 熱帶氣旋天鵝以相當於五級超級颱風的巔峰強度登陸菲律賓東部,聯合颱風警報中心估計其強度達 170 節,與 2013 年熱帶氣旋海燕看齊。天鵝於菲律賓造成嚴重破壞,亦加劇越南的水災。

Nov 1: Tropical cyclone Goni made landfall in eastern Philippines as a category-5 equivalent super typhoon. The Joint Typhoon Warning Center estimated its wind speed as 170 knots, tying with tropical cyclone Haiyan in 2013.

全年: 香港多個月份氣溫較正常高,其中冬季 (2019 年 12 月至 2020 年 2 月) 的平均高溫 21.5 度,夏季 (6 至 8 月) 的平均高溫 32.6 度、平均氣溫 29.6 度及平均低溫 27.7 度,以及秋季 (9 至 11 月) 的平均高溫 26.4 度均為歷來最高。此外,由於副熱帶高壓脊長期盤據華南,7 月成為有紀錄以來最熱的月份,該月平均溫度為 30.2 度。全年酷熱 (高溫達 33 度) 及熱夜 (低溫達 28 度) 日數分別為 47 及 50 天,均打破紀錄。

Whole year: Temperatures in various months were warmer than usual in Hong Kong. The mean maximum temperature of 21.5 degrees in winter (Dec 2019 to Feb 2020), mean max/average/min temperatures of 32.6/29.6/27.7 degrees in summer (Jun to Aug), mean maximum temperature of 26.4 degrees in autumn (Sep to Nov) were all the highest on record. In addition, due to the dominance of the subtropical ridge in southern China, July became the hottest month on record with a mean temperature of 30.2 degrees. There were 47 very hot days (max temperature reaching 33 degrees) and 50 hot nights (min temperature reaching 28 degrees) in the year, breaking their respective records.

6月21日: 非洲東部、華南及台灣等地出現日環食。由於香港頗為接近環食帶,當天下午可見食分達 0.89 的日偏食,至 2070 年前亦不會再有食分如此大的日食重臨。日食期間天文台氣溫下跌約 2 度,食甚時紫外線指數曾降至 0.4。

Jun 21: An annular solar eclipse was visible in areas such as eastern Africa, southern China and Taiwan. As Hong Kong was situated quite close to the path of annularity, a partial eclipse of magnitude 0.89 could be observed in the afternoon.

The HK Observatory recorded a 2-degree drop in temperature during the eclipse, and the ultraviolet index dropped to 0.4 at maximum eclipse.
