I reply:
 
That isn't only in direct contradiction to what I said. It's also in direct contradiction to everything I've found written on the subject. The U.S. government publishes a book of climate information for the U.S. I don't remember the title. Its figures are consistent with my claim of .75 month to 1.75 month being the usual range of variation of the seasonal timelag in the north and south temperate zones. In other words, the govt publication agrees with the Timesbooks publication.
 
In the Timesbooks tables, I looked at daily maximum and daily minimum, averaged over each month. Their lags were consistent with the about .75 month to 1.75 month usual range of seasonal timelag that I've described here.
 
As every source seems to agree, the land and the ocean have heat capacity. It takes time to heat and cool them. As a result, when the sun's declination changes, temperatures tend to lag behind those changes.
 
No, not always. At the equator, probably due to cloudiness, I didn't notice a consistent relation. In the tropics away from the equator, in the high-declination season for a particular tropical place, the .75 to 1.75 relation likewise wasn't evident to me. I noticed that, in many places in temperate South America there does seem to be little or no seasonal timelag. Of course that's possible--the timing of cloudiness could do that.
 
But, in general, in the temperate zones, all the record books that I've looked at show a lag that nearly always varies between about .75 months and 1.75 months.
