3-11-14, Monday: Using the shorter term data from Mt Boyce, as Katoomba missed too many reporting days, October average temperatures were +1.2C above average for minimums and 2.8C above average for maximums, being 8.7C and 20.4C respectively. Rainfall for the month was 62.6mm which is close to the long term average of 68.6mm. The warmest day was 28.4C on the 25th and the coolest morning was -0.6C on the 15th with about 6cm to 8cm of snow on the ground. The coolest maximum was 9C on the 14th.

9-10-14, Thursday: Using the longer term data from Katoomba, September average temperatures were +0.6C above average for minimums and 1.1C above average for maximums, being 6C and 15.7C respectively. Rainfall for the month was 44.4mm which is significantly below the long term average of 72.1mm. The warmest day was 25.1C on the 30th and the coolest morning was 2C on the 19th. The coolest maximum was 8.4C on the 6th.

4-9-14, Thursday: Using the longer term data from Katoomba, August average temperatures were +0.2C above average for minimums and right on average for maximums, being 3.5C and 11.4C respectively. Rainfall for the month was 204.2mm which is way above the long term average of 77.3mm. The warmest day was 16.4C on the 31st and the coolest morning was -1.2C on the 2nd. The coolest maximum was 5.4C on the 12th. Mt Boyce AWS (2km north of Blakcheath) average temperatures for August were 2.8C for minimums and 10.8C for maximums, which is -0.2c and -0.5C below average, respectively. Rainfall for Mt Boyce AWS was 169.6mm, well above the average of 52.5mm. Coldest maximum at Mt Boyce was 4.9C on the 12th and coldest morning was -2.4C on the 2nd. Warmest day was 15.5C on the 31st.

6-8-14, Wednesday: Using the longer term data from Katoomba, July average temps were +0.2C above average for minimums and +2C above average for maximums, being 2.8C and 11.6C respectively but the average minimum includes an anomolous -7C minimum on the 6th that has been taken out of the official recordings. Rainfall for the month was 14mm which is way below the long term average of 83mm. The warmest day was 16.7C on the 3rd and the coolest morning was -2.2C on the 12th. The coolest maximum was 5.6C on the 18th. I'm concerned that perhaps a number of these readings have been taken incorrectly as some of the readings seem wrong on certain days, compared to Mt Boyce AWS, near Blackeath. For example, the coldest day on the 18th was 2.7C milder than the same day in Blackheath and the minimum on the 12th of -2.2C was 3C colder than Blackheath. I have spoken to the BoM about this and they are looking into it.

Mt Boyce AWS July observations, with a much shorter history of around twenty years (but in recent years, perhaps more reliable than the Katoomba obs station) had 2.5C for average monthly minimums and 10C for average monthly maximums which was -0.2C and +0.5C above average, respectively. Coldest morning was -1.4C on the 8th, 13th and 18th and the coldest day was 2.9C on the 18th. Bear in mind that in certain frost hollows in Blackheath (Frog Hollow, the pool area etc) the minimums on those coldest, calm days, could have been 2C to 3C colder as cold air drains into the lowest areas during radiative cooling. Mt Boyce's warmest day was 15.3C on the 3rd. Rainfall for July was 11.6mm, well below the average of 44.2mm.

23-7-14, Wednesday: Sorry for the delay in getting the June observations up, this is a community site run in my spare time.

I'm quite concerned that a number of these readings have been taken incorrectly as some of the minimums seem way too cold on certain days, compared to Mt Boyce AWS, near Blackeath.

9-2-14, Sunday: This prolonged drought has got many people scratching their heads as the usual indicators generally suggest we shouldn't be in such a strong drought. A good article by The Land, see more here.
