Florida Major Hurricane Strikes: Still No Trend
October 11th, 2018 by Roy W. Spencer, Ph. D.
Note: The first plot had Michael’s wind speed plotted incorrectly, which has been fixed.
I’ve updated a plot of Florida major hurricane strikes since 1900 with Hurricane Michael, and the result is that there is still no trend in either intensity or frequency of strikes over the last 118 years:

Nevertheless, the usual fearmongers are claiming Hurricane Michael is somehow tied to climate change.
After all, the Gulf of Mexico is unusually warm, right?
Yes, but if you look at the history of Jul-Aug-Sept average sea surface temperature (SST) anomalies over the eastern Gulf (available here, 25N-30N, 80W-90W), you will see that since 1860, this summer is only the 9th warmest in the eastern Gulf of Mexico.
Even more astounding is that out of the top 10 warmest Gulf years since 1860, 7 occurred before 1970, which is before we experienced any significant warming.
