Disclaimer: Not my thread title idea! 2020 so far for me: warmest ever winter → so-so spring → hot summer??? Stealing the JMA stats from Karuizawa observatory which is the closest and probably most relevant "proper" observatory to me... Monthly average temperatures: So far every month except April (which was randomly quite cold) has made the top 10 warmest for the respective month. Records go back to 1925 for this location, so just shy of 100 years... Jan: warmest ever (beating previous record by 0.5C) Feb: 3rd warmest Mar: 4th warmest Apr: Actually not warm!! May: 8th warmest Jun: currently 3rd warmest - may end up 2nd depending on how today and tomorrow pan out... The JMA long range forecast is for the warm trend to continue... would love to see a return to "normal" temperatures, ie months not in the top 10th percentile! The trend seems pretty clear though :'( Nights in particular have struggled to cool down - here are June's temperatures against the 30 year average. You can see it barely dips below average all month: Also look at the plot for the last 8(?) years for july... daily lows consistently sticking above average. Not sure what has fundamentally changed to create this effect - maybe higher humidity than in the past? On a positive note, over the last week the rainy season has retreated a couple of times to give lovely spring-like days with cool (even chilly) evenings and early mornings. Making the most of them before summer proper kicks in. *I'm not a weather expert in any way, shape, or form, although I would like to be... just addicted to the stats. Here's where I get them: JMA site http://www.data.jma.go.jp/obd/stats...hp?prec_no=&block_no=&year=&month=&day=&view= That whole site is a treasure trove... don't know if any other countries publish their data so generously??
