Record Heat
Record Cold
As 100°+ heat persisted through August, it became apparent that south-central Texas was approaching an all-time summer heat record. That trend was confirmed last night when the June-August meteorological summer closed out with a record-smashing average of 88.4° at Austin Mabry, 1.7° above the previous high in one of the longest official records in the U.S. dating back to 1854. The 3 highest average summer temperatures have now been recorded at Austin since 1998. This was also the warmest June-August ever at San Antonio and Del Rio. It was the hottest August on record at Corpus Christi.
Here is the National Weather Service statement issued near midnight last night:

At he other end of the world climate and weather have been strange too.
Australia's winter has been very warm. See this post for details: http://bravenewclimate.com/2009/09/03/australias-weird-winter/ .
It is partly climate but climate has also a role.
I didn't check the post, the last sentence should read"
"It is partly weather but climate also has a role."
Wow, those temperature departures are huge for a monthly average. (U.S. readers should bear in mind that they're in °C, so they range as high as 11°F). As you say, any given day, month, or year is weather, but eventually it accumulates to be climate. Thanks for the link.
