So no where in Tasmania has a summer ? ( well they don't when I'm there....8c and pissing rain at Cradle Mountain on 30th Dec 2014 was not 'summery' haha Mind you Hobart had a 38c day in Jan 1997 when I was doing a job there...and 32c the day before. I got sun burnt to buggery....next day was 18c. I would say Launceston has a decent-ish summer. But no place in Tasmania has long summers for sure! Lmao Even Sydney doesn't have long summers to me (apart from El Nino years) |

Yep, whoops. I meant to put Brisbane's winters. But on a second thought, Brisbane doesn't really have a true winter. Their winters are like springs by world's standards. I'm guessing New Delhi will be a better contender here for having "short winters". No Brisbane has winters, they’re just warm. Highs are 8.5 c cooler than in January, that’s a sizable difference. You certainly wouldn’t say it’s spring or fall in July as it’s the coolest time of year and has the shortest days, it’s clearly winter. Exactly. Not sure why this is so hard for people to understand. |

My arbitrary definition is having average highs of 80 F (26.7 C) or above for more than three months, or means above 70 F (21.1 C) for three months or more. Somewhere like Omaha, Nebraska would be the northern limit of this. Never realized how hot Omahas summers are. 84.4/63.4 88.1/68.0 and 85.8/65.6 (means 73.9/78.1/75.7). So you wouldn't consider pittsburgh to have long summers? JJA of 79.4/59.3 82.9/63.4 and 81.7/62.0 (means 69.4/73.2/71.8). I'd say we do, but obviously preference |

I'd say we do, but obviously preference I think I focused too much on temperatures and not enough on how long and close the means stay to the warmest part of the year. I'd say Pittsburgh has pretty solidly warm summers, and a solid warm season in general, but I wouldn't call them long honestly. I'd still likely find Pittsburgh too warm of a climate for my tastes though. |

I would say that the mean temp being within 15% of the max avg mean would be summer. Phoenix's means range from 12.8°C to 35.3°C, which is 22.5°C range. 15% of that would be 3.4°C, which would make summer the period where the average mean is 32°C or higher.
For Phoenix, that is June 10th through September 15th, which is 98 days, or 26.8% of the year

Definitely not the UK - that would be the place with the longest Cocktober.

Miami, FL is in their hottest 15% of the year from June 2nd to October 8th, which is 129 days or 35.3% of the year

A short summer would be Salt Lake City. They're only in their hottest 15% from June 22nd to September 4th, which is only 75 days, or 20.5% of the year

I would say that the mean temp being within 15% of the max avg mean would be summer. That metric would make winter November 23rd to February 27th, a length of 96 days. Summer would be June 15th to September 2nd, a length of 79 days. Similarly 107 days for spring and 82 for fall. Pretty good for winter and captures that spring takes longer than fall but I’d make summer at least a week longer on either end. Average highs <50 and >80 for here seems like it would capture the seasons well here and that would pretty much line up with the period where there’s never been snow for summer. |

Coldest mean here is 11.2 F (-11.6 C) and warmest mean is 70.6 F (21.4 C). 15% warmest would be means of 61.7 F (16.5 C) or warmer. That would make summer here June 1 through September 10. Winter would be a mean 20.1 F (-6.6 C) or lower. That would make winter December 9 through February 25.
Seems about right for summer, but winter seems like too late of a start and too early of an end. I'd definitely say early March is still winter here.
Using my method (warmest 25% and coldest 25%) would give us really long summers (mean of 55.8 F or higher; May 15 - September 24) but would be about right for winter (mean of 26.1 F or lower; November 25 - March 10). So maybe warmest/coldest 20% would be happy medium for here?

The coldest and warmest mean here is 44.1°F and 71.5°F respectively. Using the 15% threshold would give means of 67.4°F for summer, and 48.2°F for winter; therefore, by that logic, summer would span from June 15th to September 8th, and winter December 13th through February 21st, which sounds a bit short for here. I like the 20% threshold better, though, then again it's relative.

Average highs <50 and >80 for here seems like it would capture the seasons well here and that would pretty much line up with the period where there’s never been snow for summer. I feel top 15% is right for summer, but winter I feel bottom 25% is more accurate. That would make Spring and fall 25th percentile to 85th percentile. So translated to Phoenix (aside from summer, which I already covered), Spring and Fall would be 18.6°C-31.7°C, and winter would be the period 18.3°C and lower. So Winter=Nov 15th to Mar 12th/118 days or 32.3% Spring=Mar 13th to Jun 9th/89 days or 24.4% Summer=Jun 10th to Sept 15th/98 days or 26.8% Fall=Sept 16th to Nov 14th/60 days or 16.4% The other reason I chose those percentiles is because there are more intrusions of cold air on the shoulders of winter than there is consistent heat in summer. And actual fall is really short most places |

For Shitchester:
Winter=Nov 28th to Mar 19th/112 days or 30.7%
Spring=Mar 20th to Jun 6th/79 days or 21.6%
Summer=Jun 7th to Sep 11th/97 days or 26.6%
Fall=Sep 12th to Nov 27th/77 days or 21.1%

So maybe warmest/coldest 20% would be happy medium for here? They're not equal percentiles. Summer is a smaller percentile of the year, due to sun position in relation to daylength. In summer, lower sun means longer days; while in winter, higher sun means longer days (we all know this). So it makes winter a much higher percentile of the year. I feel 25% is accurate for winter, while I stand by 15% for summer |

Winter and summer are long with shorter shoulder seasons. Summer longer than winter in the south winter longer in the north. |
