All of July, rather than just the 1st, which looks like it was just
short of 20 C and only F2 to F3 gusting just over 10 mph, so very
little wind chill. It would have been a calm, warm and pleasant day.
Compared to the 3rd or 4th with that F5 gusting 30 mph, air temp
below 15 C and windchill to 5 C. That's "getting a bit windy" and it
wouldn't have been very nice out. "Windy" doesn't kick in until the
upper end of F6 around 30 mph sustained.
