Editing Sylhet (section)

== Geography and climate ==
Sylhet is located in the northeastern region of Bangladesh within the Sylhet Division, the Sylhet District, and Sylhet Sadar Upazila. Sylhet has a typical Bangladeshi [[tropical monsoon climate]] ([[Köppen climate classification|Köppen]] ''Am'') bordering on a [[humid subtropical climate]] (''Cwa'') at higher elevations. The rainy season runs from April to October, and is generally hot and humid with heavy showers and thunderstorms almost every day. The shorter dry season runs from November to February, with very warm and fairly clear weather. Nearly 80% of the annual average rainfall of {{convert|4200|mm|in|-1}} occurs between May and September.<ref>[http://weather.msn.com/monthly_averages.aspx?wealocations=wc:BGXX0010&q=Sylhet%2c+BGD+forecast:averagesm Monthly Averages for Sylhet, BGD] {{Webarchive|url=https://web.archive.org/web/20190701141245/https://www.msn.com/en-us/weather/ |date=1 July 2019 }} MSN Weather.

The city is located within a topographically distinctive region of Bangladesh characterized by dramatic hills and basins. The [[physiography]] of Sylhet consists mainly of hill soils and encompasses a few large depressions known locally as "[[beel]]s," which are frequently [[oxbow lake]]s caused by tectonic subsidence during [[1762 Arakan earthquake|the earthquake of 1762]].

Geologically, the region is complex and diverse; higher-elevation regions date partly to the Plio-[[Miocene]] age. Available limestone deposits in different parts of the region suggest that the whole area was under the ocean in the Oligo-Miocene. In the last 150 years, three major earthquakes have hit the city with magnitude of at least 7.5 on the [[Richter Scale]], most recently in 1918.<ref name="ds10Feb2006">{{cite news |last=Siddiquee |first=Iqbal |date=10 February 2006 |title=Sylhet growing as a modern urban centre |url=http://archive.thedailystar.net/suppliments/2006/15thanniv/ourcities/ourcities24.htm |work=Our Cities: 15th Anniversary Special |publisher=The Daily Star |access-date=25 May 2009 |archive-date=21 July 2018 |archive-url=https://web.archive.org/web/20180721161221/http://archive.thedailystar.net/suppliments/2006/15thanniv/ourcities/ourcities24.htm |url-status=dead}}</ref>
