It’s endless summer here with a very uncomfy 94 high at KSAV. I haven’t had significant rains at my place since way back on July 14th! However, Mon into the evening is looking promising. If that weren’t to deliver, it would be sprinklers time again.

This image shows well that ‘97 was much more E based on July 19th:

Chris put out this yesterday. I hate his confrontational juvenile behavior, which is totally unnecessary. Ignoring that and acknowledging that 1936 was made much worse due to very dry soils/drought, does he have a valid point about a possible double standard in the treatment of 1936 and 2026 European heatwaves? After all, they were both regional and 1936 covered a much larger area I believe: This is the 2nd part: The recent European heatwave was also regional. But for whatever reason, that is supposedly “incontrovertible proof” of catastrophic, rapid global climate change. I really want to know how any person can have this level of mental retardation. *Also, I’ve been reading some things regarding the magnitude of the Obs Time Bias possibly being exaggerated. I’ll probably post some of this later to get your thoughts.

Out of 36 mod+ Ninos since 1850s, only 2 didn’t have NOAA +PDO by Nov: 1994/5 & 2023/4!

Through July 24th, it’s the wettest on record since way back in 1941!

To compare to the prior Nino, July was similarly strongly -PDO and it hit most neg ~Oct 1st. Then it rose to a more moderate -PDO:

WCS PDO is still dropping and is now down to -1.81, lowest since early Oct:

Thanks, Don. It will be interesting to see if 2026 beats 1998’s 100 days! As you said, the record of the daily SOs goes back only to 1991. I wonder if there’s any way to find dailies pre-1991. Based on the monthlies, I’d say that 1982-3 would have a 50% or higher chance of having a streak exceeding 100 days if the dailies could be found. Why? These monthlies, especially Nov-Mar: 1982 8 -22.2 1 1982 9 -20.0 1 1982 10 -20.5 1 1982 11 -30.0 1 1982 12 -22.6 1 1983 1 -31.4 1 1983 2 -35.7 1 1983 3 -25.7 1 Another good candidate per the monthlies is 1905, especially Mar-June: 1905 2 -18.5 3 1905 3 -27.7 1 1905 4 -38.2 1 1905 5 -34.3 1 1905 6 -27.7 1 1905 7 -19.8 1 One last good possibility is 1896, especially May-Aug: 1896 5 -38.8 3 1896 6 -27.0 1 1896 7 -19.1 1 1896 8 -21.0 1 1896 9 -18.2 1 1896 10 -19.2 1

Yep, extent is doing worse than area as compared to recent years.

-SOI has reached 74 straight days! That will continue supporting robust warming of Nino 3.4.

Parts of Houston metro received significantly more rainfall from Bertha than models had with up to ~5” vs mist progs of ~0.75”. Here’s the final advisory: BULLETIN Remnants Of Bertha Advisory Number 19 NWS National Hurricane Center Miami FL AL022026 1000 PM CDT Thu Jul 23 2026 ...BERTHA HAS DEGENERATED INTO A TROUGH... ...THIS IS THE LAST ADVISORY...

Most Senators were alive during the 1974 year-round DST disaster that was thus quickly reversed. And can you imagine not getting the Euro til 2AM during the crucial winter season?

The current -SOI streak has now surpassed the 72 day streak of 1997 and is now at 74 days. Only 1998’s 100 days has been longer as far back as daily records go at Long-Paddock: https://data.longpaddock.qld.gov.au/SeasonalClimateOutlook/SouthernOscillationIndex/SOIDataFiles/DailySOI1887-1989Base.txt

Chris, June-July 1991 also didn’t get the memo (Also, May of 1991 was very warm): In addition, June-July of 1877 wasn’t cool.

Thanks, Don! This is the first time I can recall becoming aware of this observation time bias potentially causing overcounting of high max temps due to double counting of these highs as a result of observers getting 24 hour max prior to 1940s during late afternoon, near the time of most very hot highs, as opposed to mainly doing it near sunrise 1940s+. Do you have a source with more details on this? How widespread was this practice of getting 24 hour max late in afternoon? Do you by chance know how often this would result in double counting hot highs?
