What a month of weather it’s been. We’ve had out fair share of rain, but not without the odd glimpse of spring. To keep us clued up on all the weather stats from July, our reliable Weather Ferret JR has the numbers hot off the presses, as some hints on what to expect in August.

Wet, wild, and… Warm?

In good news for our dams, we exceeded our July rainfall average for the first time in nine years. Our 172.6mm was just above the average of 167.7mm, and we recorded it over 24 rain days. July was in fact our wettest month in general since July 2008, and it included the most rain days in one month since 1974. However, we still fell short of our all time record of 29 rain days for July, which was set in 1946. Despite besting the July average, we still didn’t reach the average rainfall over the seven months from January to July. Our 537.6mm was just short of the average of 543.0mm.

Despite the higher than usual amounts of rain, we had some unseasonably warm nights. Our mean minimum temperate for night time was 10.2°C, which is a fair way above the average of 7.8°C. July’s nights were our warmest in 17 years, and are a far cry from last year’s average of only 7.5°C. The good news for those opposed to blankets is that we only had one officially cold night this July. A cold night is anything below 5°C.

Spot on

While the night time temperatures were a bit all over the place, we hit the nail on the head for day time averages, with a mean max of 18.4°C. Despite the standard temperatures, we still had a dull July. We only had an average of 5 hours of sunshine per day, below the average of 6.1 hours. Still, it doesn’t compare to 1926, when the average was just 3.2 hours.

What to expect

Here’s some quick tips on what to expect for the rest of August:

  • The average rainfall for August is 132.9 mm 15.8 rain days
  • Last August (2016), Perth recorded 123.2 mm on 19 days
  • The warmest day in August is 27.8°C on 21st August 1940
  • On 15th August 2015, Perth recorded a max temp of 27.0°C.
