London's lengthy streak of temperatures averaging above normal finally came to an end on Tuesday, but that does not mean that summer warmth is over for 2013.
With a high of 21.5 degrees C (71 degrees F) and a low of 10 degrees C (51 degrees F), temperatures averaged 1.3 degrees C (2 degrees F) below normal on Tuesday.
That makes Tuesday London's first below-normal day since July 2, when temperatures averaged 1.9 degrees C (3 degrees F) below normal.
Between Tuesday and July 2, temperatures averaged as much as 8.1 degrees C (15 degrees F) above normal on both July 22 and Aug. 1. The latter date holds the distinction of London's hottest day of the year with a high of 34.1 degrees C (93 degrees F).
Tuesday's cool weather however, is not a sign that summer is over for London.
Temperatures will remain closer to normal through the remainder of this week and early next week before a warm surge likely follows for next Wednesday through Friday.
"Temperatures could spike to 30 or 31 degrees C (the upper 80s F) on the hottest day during that stretch," stated AccuWeather.com Expert Senior Meteorologist Jason Nicholls.
