昨天涼了一天，今早氣溫已回升，下週初又回到25度以上。甚麼時候才真正冷？ 上表顯示過去三十年（1991－2020）秋冬季香港天文台氣溫首次降至15度或以下（左）及12度或以下（右）的日期。左表顯示，十一月下旬（小雪節氣）天氣開始轉涼。今年轉涼的時間（11月23日）稍早，但屬正常。 右表則顯示寒冷天氣出現的時間。多數在十二月中旬（大雪至冬至節氣）出現。有趣的是，有四年的首次寒冷天氣都在12月17日出現。另外，2000年以前寒冷天氣出現的時間比較遲，有些年份要到翌年一月。而最遲的一年是2019年，要到翌年的1月27日。 今年如何？拭目以待。<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[51],"tags":[],"class_list":["post-3595","post","type-post","status-publish","format-standard","hentry","category-51"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3595","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/comments?post=3595"}],"version-history":[{"count":7,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3595\/revisions"}],"predecessor-version":[{"id":4518,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3595\/revisions\/4518"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=3595"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=3595"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=3595"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
