===Monsoons===
====Period====

In mid-June or early July, the monsoon season starts.

====Temperature====

In most places, the temperature drops as cloud cover increases. This is less true for the mountains and the Terai Dooars plains, where temperature gradually increases until August.

The maximum temperature of South Bengal's plains and western highlands is 32 °C,<ref>{{cite web|url=https://eisamay.indiatimes.com/west-bengal-news/others/july-2019-is-warmest-july-on-record-for-south-bengal/amp_articleshow/70222353.cms|title=১০ বছরে উষ্ণতম জুলাই, শহরে ৩৭ ডিগ্রি!|accessdate=5 November 2020}}</ref> 31 °C in North Bengal plains and around 19–20 °C in mountains. Sometimes when the sky gets clear, the temperature rises suddenly. This is known as a '''monsoon break'''. This occurs mostly in North Bengal plains and in mountains in July and August when the temperature soars over 36 °C and 24 °C respectively.<ref>{{cite web|url=https://www.anandabazar.com/state/siliguri-facing-trouble-in-scorching-heat-damaging-tea-leaves-in-doors-1.184013|title=গরমে নাকাল শিলিগুড়ি|accessdate=30 October 2020}}</ref><ref>{{cite web|url=https://www.anandabazar.com/district/north-bengal/siliguri-burning-in-scorching-heat-1.1028383|title=ঘড়িতে সাড়ে বারোটা, পারদে ৪০ ডিগ্রি|accessdate=30 October 2020}}</ref><ref>{{cite web |url=https://www.aajkaal.in/news/state/state-mercury-rises-9fjm|archive-url=https://web.archive.org/web/20201102071805/https://www.aajkaal.in/news/state/state-mercury-rises-9fjm|url-status=dead|archive-date=2 November 2020|title=দার্জিলিঙে ঘুরছে পাখা, সমতলে ৩৯ ডিগ্রি!|accessdate=30 October 2020}}</ref><ref>{{cite web |url=https://www.anandabazar.com/district/north-bengal/weather-update-temperature-is-41-degree-even-in-the-rainy-season-1.1031124|title=রেকর্ড ভেঙে ৪১ ডিগ্রিতে জলপাইগুড়ির পারদ|accessdate=30 October 2020}}</ref><ref>{{cite web|url=https://www.marinetoalpine.com/news/mercury-up-in-sikkim-tour-operators-fear-drop-in-flow-of-visitors-to-hills-20180821115856.html|title=Many parts of Sikkim is feeling above 30 degrees temperatures|accessdate=1 November 2020}}</ref>

===Autumn===
====Period====

Autumn lasts for two months, October and November.

====Temperature====

In autumn, the southwest monsoon wind returns and clears the sky. So, the state gets enough sunshine to be warm in the day and releases a lot of heat to be cool at night.

At this time, a maximum temperature of 30–33 °C is felt over the plains and 17–19 °C in mountains. The minimum temperature is normally around 19–22 °C in plains and 6–11 °C in mountains.<ref>{{cite web|url=http://www.imdkolkata.gov.in/|title=Regional Meteorological Department, Kolkata |accessdate=9 November 2020}}</ref> Sometimes, cold waves blow over the state in autumn.<ref>{{cite web|url=https://bangla.asianetnews.com/kolkata/weather-update-on-8-november-in-kolkata-and-west-bengal-rtb-qjgjbm|title=শহর-শহরতলির তাপমাত্রা নামল স্বাভাবিকের ৩ ডিগ্রি নীচে, দেশজুড়ে শৈত্যপ্রবাহের সতর্কতা |accessdate=8 November 2020}}</ref><ref>{{cite web|url=https://www.smritinews.in/rain-possibilities-in-this-districts/|title=রাজ্যের ৫ জেলায় বৃষ্টির পূর্বাভাস, শৈত্যপ্রবাহ নিয়ে বিশেষ সতর্কবার্তা দিল হাওয়া অফিস|date=6 November 2020|accessdate=8 November 2020}}</ref><ref>{{cite web|url=https://www.kolkata24x7.com/north-bengal-weather-update-5/|title=উত্তরে যেমন নামছে পারদ, সঙ্গে মিলছে বৃষ্টির পূর্বাভাস|accessdate=8 November 2020}}</ref>

====Rainfall====

In autumn, the southwest monsoon wind returns, and the northeast monsoon wind enters West Bengal. Due to their collision in [[Bay of Bengal]], some cyclones are created.<ref>{{Cite web|url=https://economictimes.indiatimes.com/topic/Cyclone-Bulbul-in-West-Bengal/amp|title=Cyclone Bulbul in West Bengal: Latest News & Videos, Photos about Cyclone Bulbul in West Bengal | the Economic Times - Page 1}}</ref><ref>{{Cite web|url=https://timesofindia.indiatimes.com/topic/Bay-of-Bengal-Cyclone/ampdefault|title=Bay of Bengal Cyclone: Latest News, Videos and Bay of Bengal Cyclone Photos | Times of India|website=[[The Times of India]]}}</ref> The cyclones cause some rainfall in the state.
