== Climate ==
{{See|Climate of Sydney}}
Parramatta has a [[humid subtropical climate]] ([[Köppen climate classification]]: ''Cfa'') with mild to cool, somewhat short winters and warm to usually hot summers, alongside moderate rainfall spread throughout the year.

Summer maximum temperatures are quite variable, often reaching above {{cvt|35|C|F}}, on average 13.1 days in the summer season, and sometimes remaining in the low 20s, especially after a [[cold front]] or a [[sea breeze]], such as the [[southerly buster]]. Northwesterlies can occasionally bring hot winds from the [[Australian desert|desert]] that can raise temperatures higher than {{cvt|40|C|F}} mostly from November to February, and sometimes above {{cvt|44|C|F}} in January severe heatwaves. The record highest temperature (since 1967) was {{cvt|47.0|C|F}} on 4 January 2020. Parramatta is warmer than [[Sydney CBD]] in the summer due to the [[urban heat island effect]] and its inland location. In extreme cases though, it can be {{cvt|5–10|C-change|0}} warmer than Sydney, especially when sea breezes do not penetrate inland on hot summer and spring days. For example, on 28 November 2009, the city reached {{cvt|29.3|C|F}},<ref>{{Cite web |title=Daily Maximum Temperature – 066062 |publisher=Bureau of Meteorology |url=http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=122&p_display_type=dailyDataFile&p_startYear=2009&p_c=-872833047&p_stn_num=066062 |website=bom.gov.au| access-date=2016-02-03}}</ref> while Parramatta reached {{cvt|39.0|C|F}},<ref>{{Cite web |title=Daily Maximum Temperature – 066124 |publisher=Bureau of Meteorology |url=http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=122&p_display_type=dailyDataFile&p_startYear=2009&p_c=-874472154&p_stn_num=066124 |website = bom.gov.au |access-date=2016-02-03}}</ref> almost {{cvt|10|C-change}} higher. In the summer, Parramatta, among other places in western Sydney, can often be the hottest place in the world because of the [[Blue Mountains (New South Wales)|Blue Mountains]] trapping hot air in the region, in addition to the UHI effect.<ref>{{cite news |url=https://www.theguardian.com/australia-news/datablog/2023/may/23/which-australian-city-has-the-best-weather-climate-most-sunny-days-where-should-i-live-interactive |title=Which Australian city has the weather that suits you best?

Rainfall is slightly higher during the first three months of the year because the anticlockwise-rotating [[subtropical high]] is to the south of the country, thereby allowing moist easterlies from the [[Tasman Sea]] to penetrate the city.<ref>[https://www.bioregionalassessments.gov.au/assessments/11-context-statement-sydney-basin-bioregion/1123-climate Context statement for the Sydney Basin bioregion – Climate] by Bioregional Assessments from the [[Australian Government]].

Snow is virtually unknown, having been recorded only in 1836 and 1896<ref>{{cite web|url=http://www.blackheathweather.com/bmsnowhistory1.html|title= NSW NON ALPINE SNOW FALL EVENTS 1808 TO 2017|website=blackheathweather.com}}</ref> Parrammatta gets 106.6 days of clear skies annually.

Depending on the [[wind direction]], summer weather may be [[humid]] or [[Drought|dry]], though the humidity is mostly in the comfortable range, with the late summer/autumn period having a higher average humidity than late winter/early spring.
