After a slight false start to winter, there’s no denying the chill and rain are here. However, there’s an end in sight. Last Sunday marked the halfway point of winter, so let’s take a look at the stats so far, courtesy of our Weather Ferret, JR.

Halfway there

With half of winter done and dusted, we can look at some of the numbers. For those rain fans, the news is bad. Statistically the first half of winter is usually wetter. The average is 257.6mm over the period of June 1 to July 16. We’ve had a grand total of 160.0mm, so there’s a bit of catching up to do in order to reach the average total of 473.5mm. However, we’re relatively on track to reach the total rainfall received last year, which was 372.2mm. While that may seem like a lot, it’s still below average. In fact, the last time Perth exceeded the average was 17 years ago in 2000, when we recorded 497.2mm.

This week

Looking more short term, it looks like we’re in for some solid rain this week, with the chance of a thunderstorm and 8 to 25mm on Thursday. This may seem like a fair drenching, but it’s a fair way short of the record for the wettest July day in Perth. On the 29th of July 1987 Perth received 95.0mm of rain in one day.

Up north

Overnight the Kimberly recorded both the coolest and warmest minimum temperatures for the state. Mandora dropped to just 5.7°C, their coldest night since July 26 last year, when the mercury dropped to 4.1°C. In contrast, Troughton Island only dipped to 23.0°C overnight, making for a fairly toasty winter sleep.

On this day

On this day in 1976 Perth recorded it’s equal warmest July day on record. The temperature peaked at a balmy 26.3°C. Just for good measure, this temperature was repeated the following day. It’s a fair step above the usual July average of 18.4°C.
