Interestingly, all seasons except SPRING got warmer. Spring instead became more extreme, March/April/early May actually became COLDER, with increased likelihood for late April/early May snow, while late May and beyond got hotter with a more abrupt transition from cold weather to hot weather.
The other seasons got much warmer from what I recall in the early 2000s. December and January were always known for those very cold mornings with low windchills and none of this mild rainy stuff. 2000 was the only cool and dry summer of the century, any other summer is either hot and dry, OR cool with rain and thunderstorms almost every day. Autumn feels like it has warmed up to the most extreme extent. For 4 years in a row we had long stretches of warm weather in October or November. 2020 saw 7 days in a row of 20+C in a time of the year in November which normally has 10C average, and 2022 saw 25C in November. 2023 saw 30C in October.

Since I live under El Niño and La Niña, these weather forces make contrasting results. In El Niño, we are getting hotter, drier and sunnier, like 2018-2020 (and blimey, bloody bushfires!). In La Niña, we get dumped by monsoonal easterlies, like 2022, with lots of cloud and cooler summers.

All seasons got hotter, especially the min temps. In the 1960s, it was said that by the end of September you have to wear a blanket at late night to avoid getting cold. But now 30+ nights continue into October.
Also, summer rain has been increasing in frequency, though still exceedingly rare. I remember 28 July 2022 when we got 74.9 mm of rain. Some climate models suggest that global warming may allow the Indian summer monsoon to extend into south-eastern Arabian Peninsula. It would be really interesting to experience a monsoonal southern Persian Gulf even if it's a relatively weak one.

Global warming is affecting min temps more than max temps.

I live in Seattle, WA, USA and I have noticed: Hotter summers with more 90°F+ days. Spring and fall with more hot days as well. As for winter, we're not getting the extreme cold we got in the 20th century but El nino/la Nina impact our winters heavily. We've gotten decent snowfall and some winter months below normal temperature-wise for the past 3 (la Nina) years. But I think that overall winters are getting milder, and even more so with el nino. More extreme atmospheric rivers resulting in a large amount of precipitation in a short amount of time also seem to be a trend Yes the number 90F+ weather has increased a lot in past decade, some of it can be attributed to urban heat island effect, but there is definitely a lot more going on. Average number of days >= 90F by decade in Seattle. 2014-2023: 8 days 2004-2013: 4 days 1994-2003: 2 days 1984-1993: 4 days 1974-1983: 3 days 1964-1973: 3 days 1954-1963: 3 days 1944-1953: 1 day Weather station moved from Dowtown to SeaTac. 1934-1943: 2 days 1924-1933: 1 day 1914-1923: 0 days 1904-1913: 1 day 1894-1903: 1 day Source: www.weather.gov/wrh/Climate?wfo=sewHowever the duration of our extreme Arctic blasts hasn’t changed all that much. Average number of days <= 20F by decade at SeaTac 2014-2023: 1 day 2004-2013: 1 day 1994-2003: 0 days 1984-1993: 2 days 1974-1983: 2 days 1964-1973: 1 day 1954-1963: 2 days 1944-1953: 2 days Weather station moved from Dowtown to SeaTac. 1934-1943: 1 day 1924-1933: 3 days 1914-1923: 2 days 1904-1913: 2 days 1894-1903: 1 day |

Weather in the Midwest is so volatile that it's impossible to say what's caused by climate change and what is just typical variation. As I like to say "Welcome to the Midwest, where the seasons are made up and the months don't matter!"
The only thing I've noticed is that winters aren't as cold as they used to be, we have more days in the 40s in DJF and snowpack isn't constant anymore.

All seasons got warmer, but seems like March and August-September got affected the most. Monsoon seasons are getting more severe. Either lasting extremely long, or having periods of intense rain.
Minimums are definitely more affected than the highs. Extremely humid temperatures are starting to last deep into September. 2023 set a record for the warmest September on record by quite a bit, then 2024 came along and somehow completely OBLITERATED the previous year's temperatures

Aside from all seasons being warmer, our precipitation pattern has changed a bit. Rainfall in the cooler months has decreased over time as a result of fewer fronts from the Southern Ocean. Meanwhile, warm season rainfall has remained similar or increased slightly. In the eastern suburbs of Melbourne, we’ve always had evenly distributed rainfall with a semi-Med aspect to it, but it’s becoming less distinct. After all, November and December are our wettest months in the 1991-2020 normals.
