Canberra Airport record low min temp/first sub-0C summer min temp

[Ken Kato]

Looks like the Canberra Airport site's min temp this morning of -0.3C has broken its record for lowest summertime min temp (previous record was 0.3C set back in Dec 2012), albeit still near the start of summer when the odd cool or cold snap can still occur.

Apparently it's also its first sub-0C summertime min temp on record as well.

Some of the cool air (by summer standards) has also started to spread up here into Southern QLD, with pleasant midday temps of 17.3 degrees in Applethorpe and a feels-like of 11.1.... and 19.3 degrees in Toowoomba, with a feels-like of 11.5

Apparently the previous site was colder on average though.

Hi Ken.

 

That is a damn cold start for December. The last few weeks here have been as windy as, and quite cool. Good for me as I don't go real well in the consistent heat.

 

Regards Bussy

The current site is colder for mins than its predecessor and that shows up particularly on cold nights in the warm season. Still impressive though.

Ah yes, I got it mixed up the other way around.

Hi Ken, Bussy and all,

I have just had a chance to look through my observations, having heard of the record minimum on the media.

The readings for Canberra Airport, Tuggeranong AWS and my PWS site at Gilmore North are as follows.

!st ; Canberra A/P; Min 7.4 Max 19.0

       Tuggeranong AWS; Min 6.8 Max 18.5

       Gilmore Nth.; Min 7.8 Max 19.4

2nd. Canberra A/P; Min -0.3 Max 21.9

        Tuggeranong AWS; Min. 1.2 Max 21.9

         Gilmore Nth.; Min 3.5 Max 23.2

3rd, Canberra A/P; Min 4.4

        Tuggeranong AWS; Min, 3.2

        Gilmore Nth; Min, 5.9

Looking at my records here since 1991 for December, our record coldest minimum was 1.3 degrees on December 27th, 2001.We have recorded six mornings at or below Monday's Minimum temperature since 1991.

 I must add that we are located on the urban fringe on the northeastern side of the Tuggeranong Valley, with the summit of Gilmore Hill at 690 metres located about 500 metres to our northeast. Our elevation is 660 metres while the Airport and Tuggeranong AWS are around 560 metres, the airport on a wide plain and Tuggeranong AWS adjacent to Tuggeranong Creek, both prone to cold air drainage, which is rare or nonexistent at our location.

There was a very light WSW to SW breeze between 2-3 km /hr for the period to 0520 then calm from 0530 to 0620 with the Minimum Temperature at 0540hours.

Regards,

Gavin
