It’s been an up-and-down month in terms of weather. One day it’s sunny, the next it’s pouring down. However, there’s only one week left, so let’s take a look at some of the stats for this month. Our resident rain-gauge guru JR the Weather Ferret hooked us up with the news.

A brief taste of spring

Last Tuesday Perth got a bit of a teaser of what’s coming up later this year. We had a warm sunny day, with a very spring-like maximum of 25°C. It was Perth’s warmest July day since 1999, when we hit 25.4 on July 24. However, it was a fair way short of the warmest July day on record, a balmy 26.3°C recorded on the 17th and 18th of July 1976.

Despite the one day warm spell, we’re spot on average maximum temperature for July so far, which is 18.4°C. Last year we were below that average, with a mean maximum of 17.3°C, the coolest average since July 1998, which had an average of 16.7°C.

Wet days, warm nights

We’ve had 19 rain days this July, and many cloudy days, which has meant that we’ve experienced some warmer than average July nights. The mean minimum temperature this month so far is 10.0°C, which is a bit warmer than the average of 7.8°C. this is the warmest night time average Perth has experienced since 2000, when the average was 10.9°C.

Despite the warm nights, we’re still experiencing a dull July. We’re sitting on an average of 5.0 hours of sunshine per day, compared to the average of 6.1. This is the lowest average since we experienced a low of 4.3 hours in 1996. That’s nothing compared to the dark and dreary July of 1926, when Perth had an average of just 3.2 hours of sun per day.

Second best

We’ve had a fair amount of rain this month, 118.6mm on 19 rain days. Despite this, July is still not the wettest month of the year. This honour is still surprisingly held by February. The 137.2mm of rain recorded in February is mostly due to the 114.4mm recorded on the 10th of February.
