I expect John meant that the land takes longer to warm up, than it would
if there were no chill onshore air systems?? - but faster than the oceans
This is an interesting map of the Hottest Day.

Notice the ribbon of delayed hot days along the Pacific coast?Not the Atlantic coast though.

If the winter solstice occurs on December 21, that may put the coldest day 75 to 80 days later? 
 That would be March 4th to 9th?
