Editing Portland, Maine (section)

===Climate===
Portland has a [[humid continental climate]] ([[Köppen climate classification|Köppen]]: ''Dfb'', closely bordering on ''Dfa''), with cold, snowy, and often prolonged winters, and warm to hot, yet relatively short summers. The monthly average high temperature ranges from roughly {{cvt|30|°F|0}} in January to around {{cvt|80|°F|0}} in July. Daily high temperatures reach or exceed {{cvt|90|°F|0}} on only four days per year on average, while cold-season lows of {{cvt|0|°F|0}} or below are reached on 10 nights per year on average.<ref name="Portland weatherbox NOAA"/> The area can be affected by severe [[nor'easter]]s during winter, with high winds and snowfall totals often measuring over a foot. Annual liquid precipitation (rain) averages {{cvt|47.2|in|sigfig=3}} and is plentiful year-round, but with a slightly drier summer. Annual frozen precipitation (snow) averages {{cvt|69|in|cm|0}} in the city. However, this number can fluctuate seasonally from as little as 30 inches to as much as 150 inches, depending on a multitude of factors. In Southern Maine, snowstorms can be intense from November through early April, while warm-season thunderstorms are somewhat less frequent than in the Midwestern, Mid-Atlantic, and Southeastern U.S. (although their frequency has increased in recent years).<ref>{{Cite web |title=Changing Thunderstorm Potential {{!}} Climate Central |url=https://www.climatecentral.org/climate-matters/changing-thunderstorm-potential |access-date=2023-02-28 |website=www.climatecentral.org |language=en}}</ref> Direct strikes by hurricanes or tropical storms are rare, partially due to the normally cooler Atlantic waters off the Maine coast (which usually weaken tropical systems), but primarily because most tropical systems approaching or reaching 40 degrees North latitude recurve (due to the Coriolis force) and track east out to sea well south of the Portland area. Extreme temperatures range from {{cvt|−39|°F|0}} on February 16, 1943, to {{cvt|103|°F|0}} on July 4, 1911, and August 2, 1975.<ref name="Portland weatherbox NOAA"/><!-- defined by template: Portland, Maine weatherbox --> The [[hardiness zones]] are 5b and 6a.
