Mississauga covers {{convert|288.42|km2}} of land,<ref name=census>{{cite web |url=http://www12.statcan.ca/english/census06/data/profiles/community/Details/Page.cfm?Lang=E&Geo1=CSD&Code1=3521005&Geo2=PR&Code2=35&Data=Count&SearchText=Mississauga&SearchType=Begins&SearchPR=01&B1=All&Custom= |title=Community Profile, City of Mississauga |work=[[Statistics Canada]], 2006 Census of Population |date=13 March 2007 |access-date=2007-03-14 |archive-date=12 September 2007 |archive-url=https://web.archive.org/web/20070912163313/http://www12.statcan.ca/english/census06/data/profiles/community/Details/Page.cfm?Lang=E&Geo1=CSD&Code1=3521005&Geo2=PR&Code2=35&Data=Count&SearchText=Mississauga&SearchType=Begins&SearchPR=01&B1=All&Custom= |url-status=dead }}</ref> fronting {{convert|13|km}} of shoreline on [[Lake Ontario]].

Mississauga is bounded by [[Oakville, Ontario|Oakville]] and [[Milton, Ontario|Milton]] to the west/southwest, [[Brampton]] to the north, Toronto to the east, and Lake Ontario to the south/south-east. [[Halton Hills, Ontario|Halton Hills]] borders Mississauga's north-west corner. With the exception of the southeast border with Toronto (Etobicoke Creek), Mississauga shares a land border with all previously mentioned municipalities.

Two major river valleys feed into the lake. The [[Credit River]] is by far the longest with the heaviest flow, it divides the western side of Mississauga from the central/eastern portions and enters the lake at the [[Port Credit, Ontario|Port Credit]] harbour. The indented, mostly forested valley was inhabited by first nation peoples long before European exploration of the area. The valley is protected and maintained by the Credit Valley Conservation Authority (CVCA).<ref name="Mississauga's Natural Areas">{{cite web|title=Mississauga's Natural Areas|url=http://www5.mississauga.ca/rec&parks/pdfs/MississaugaNaturalAreas.pdf|website=5.mississauga.ca|access-date=26 September 2014}}</ref>

[[Etobicoke Creek]] forms part of the eastern border of Mississauga with the city of Toronto. North of there it passes through the western limits of [[Toronto Pearson International Airport|Pearson Airport]]. There have been two aviation accidents, in 1978 and 2005 where aircraft overshot the runway and slid into the Etobicoke creek banks. In 1954, heavy flooding resulted in some homes along the riverbank being swept into the lake after heavy rains from [[Hurricane Hazel]]. Since that storm, houses are no longer constructed along the floodplain. The creek and its tributaries are administered by the [[Toronto and Region Conservation Authority]] (TRCA).<ref>{{cite web|last1=Campion-Smith|first1=Bruce|title=Air France sues over crash|date=4 June 2008|url=https://www.thestar.com/news/canada/2008/06/04/air_france_sues_over_crash.html|publisher=Toronto Star|access-date=26 September 2014}}</ref>

Most land in Mississauga drains to either of the two main river systems, with the exception of the smaller Mary Fix and Cooksville Creeks which run roughly through the centre of Mississauga entering the lake near Port Credit. Some small streams and reservoirs are part of the [[Sixteen Mile Creek (Ontario)|Sixteen Mile Creek]] system in the far north-west corner of the city, but these drain toward the lake in neighbouring Milton and Oakville.

The shoreline of former [[Glacial Lake Iroquois]] roughly follows the Dundas Street alignment, although it is not noticeable in some places but is more prominent in others, such as the site of the former brickyard (Shoreline Dr. near Mavis Rd.), the ancient shoreline promenteau affords a clear view of downtown Toronto and Lake Ontario on clear days. The land in Mississauga in ranges from a maximum elevation of 214&nbsp;m (699&nbsp;ft) ASL in the far western corner, near the Hwy. 407/401 junction, to a minimum elevation at the Lake Ontario shore of 76&nbsp;m (249&nbsp;ft) above sea level.

Apart from the embankments of Credit River valley, it tributaries and the Iroquois shoreline, the only noticeable hills in Mississauga are actually part of the former [[Britannia Landfill]], now a golf course on Terry Fox Way.

On August 17, 2024, heavy rainfalls caused localized flooding in areas across the city. The floods caused many traffic disruptions as well as dangerous road conditions and road closures. All creeks and rivers throughout Mississauga were either at full capacity or flooded into parks and greenspaces.<ref>{{cite web|url=https://www.gtamoldremoval.com/mississauga-flooding.html|title=Severe Thunderstorms and Heavy Rain Cause Local Flooding and Closures|work=gtamoldremoval.com|accessdate=17 August 2024}}</ref>

===Climate===
Mississauga's climate is similar to that of Toronto and is considered to be moderate,<ref name= weather>{{cite web|url = http://www.mississauga.ca/portal/discover/weather |title = About Mississauga: Weather |publisher = City of Mississauga |access-date = 20 September 2015}}</ref> located in [[plant hardiness zone]] 6b.<ref name=hardiness>{{cite web |url=http://www.planthardiness.gc.ca/?m=22&lang=en&prov=Ontario&val=M |title=Plant Hardiness Zone by Municipality |work=Plant Hardiness of Canada |publisher=Natural Resources Canada |access-date= 6 April 2016}}</ref> Under the [[Köppen climate classification]], Mississauga has a [[humid continental climate]] (''Dfa/Dfb'').<ref name=Peel>{{cite journal | author=Peel, M.

During snowfalls when temperatures hover close to freezing, northern parts of the city, such as around Derry Road, including Pearson Airport away from warmer Lake Ontario usually get more snow that sticks to the ground because of the lower temperatures, often when rain transitions into snow or mixed precipitation.{{citation needed|date=April 2024}} The reverse occurs when a strong storm approaches from the south kicking up [[lake effect snow]], bringing higher snowfall totals to south Mississauga. 
The city usually experiences at least six months of snow-free weather; however, there is the odd occurrence where snow does fall either in October or May, none which sticks to the ground.{{citation needed|date=April 2024}} The Port Credit and Lakeview areas have a micro-climate more affected by the proximity of the open lake, warming winter temperatures as a result, but it can be sharply cooler on spring and summer afternoons, this can also be the case in Clarkson, but with much less consistency.{{citation needed|date=April 2024}}

Most thunderstorms are not severe but can occasionally bring violent winds. The last known tornado to cause significant damage touched down on 7 July 1985, when an F1-rated tornado struck an industrial park in the Meadowvale area (Argentia Road), heavily damaging some buildings and some parked tractor trailers. A relatively strong tornado tore a path across Mississauga (then part of Toronto Township) on 24 June 1923, cutting a swath from present-day Meadowvale to near Cooksville, killing four people and causing massive property damage in a time when most of Mississauga was still rural farmland dotted with fruit orchards.<ref name="1985 tornado record meteo">{{cite web|title=Tornado F0, Ontario 1923-6-24 #23|url=http://www.recordmeteo.com/tornado-canada/Tornado-Ontario-1923-6-24-en-23.html|archive-url=https://web.archive.org/web/20140714132911/http://www.recordmeteo.com/tornado-canada/Tornado-Ontario-1923-6-24-en-23.html|url-status=dead|archive-date=14 July 2014|access-date=7 June 2014}}</ref><ref name="Climate History">{{cite web|title=Mississauga Climate History|url=http://www.myweather2.com/City-Town/Canada/Ontario/Mississauga/climate-profile.aspx|access-date=26 September 2014}}</ref><ref name="Tornado F0">{{cite web|title=Tornado F0, Ontario 1923-6-24 #23|url=http://www.recordmeteo.com/tornado-canada/Tornado-Ontario-1923-6-24-en-23.html|archive-url=https://web.archive.org/web/20140714132911/http://www.recordmeteo.com/tornado-canada/Tornado-Ontario-1923-6-24-en-23.html|url-status=dead|archive-date=14 July 2014|access-date=26 September 2014}}</ref>
