Exactly, 100% humidity with a temp of 36c implies a dew point of 36c. Yeah, nah...

I'm not sure how you could get an apparent temp of 47C in February 2015 if the highest recorded actual max for the month was only 36C. But then I'm not clear on how the apparent temp is arrived at.

Sunday still looking good. Southerly comes through with good strength and timing, upper low over SEQ, 24 degree dewpoints and low 30s temperature, slow steering, 1500+ CAPE. Looks like a very nice set-up for torrential downpours.

36C forecast here from Thursday to Sunday with no real rain in sight apart from Sunday's possible storms, which usually never make it up this far anyway. I hate this summer.

According to the noaa website's heat index calculator, a temperature of 36 degrees with humidity of 70% gives a heat index reading of 54 degrees, and a dewpoint of 29.6 degrees. Sounds plausible on a really sticky day.

High Max Temps and dewpoint to go with it? Then its not just Sunday that has potential for storms? From Thursday instability looks to creep in and with those surface temps. Kinda interesting..

Well that day back at emerald at 47c in shade was before any such thing as apparent temp existed , but the reality is , in areas like that , when it's 47c in shade , real hum is bugger all. However , it doesn't matter , it's simply bull$hit hot.

The rain is coming, when it starts I think we will be praying for it to stop.

I am praying for it to start.
After it starts, then we might hope it stops...., after about a couple of weeks, maybe.

But all these 'heatwaves', really, is it not just the normal hot spells we get every summer? The temps aren't anything different to what I've seen here every year, why are they going on about it like it's abnormal? What am I missing?

Just the no rain bit Lani, about half normal for the year, year before was't much better i think. For my area anyway.

Heatwaves aren't as exciting and obviously dangerous as say a cyclone, but they kill significant numbers of people, perhaps quite a few more. I think I remember reading some discussions somewhere pushing for stronger warnings on heatwaves due to this fact.

According to wikipedia the 2009 heat wave caused between 2 and 374 deaths. The 2 being from news reports close to the event and the 374 figure being based on an analysis of an increase in death rates.

I have to agree, a stretch of temperatures into the mid-30s is hardly unusual. The dryness continuing into January isn't unheard of either - February and March tend to be when we have the best chance of getting the big rain events.

My understanding of heat wave is not so much the day time temps but where the night time gets down to for body recovery.
Check this out from BOM and have a look at the table towards the end, Thargomindah staying at 35 for min temp

While summer is no stranger to these kinds of upcoming temps, they're still significantly above what's more typical for this time of year e.g. the current official Brisbane forecast calls for max temps ranging between 34 and 36C across the next 5 days which puts them well within the hottest 10% of Jan max temps (threshold for the current site is 33C). Afternoon seabreezes often temper the max temps in Brisbane before they get too high so anything reaching the mid 30's or higher for a number of days is significant.

But perhaps more importantly (and as Mike mentioned), a heatwave and its effects isn't just about how hot it gets during the day - it's the duration, how hot the nights are, what's typical for that place and time of year and what recent conditions have been like prior to the heatwave that are just as important. These have been shown to have a big effect on the ability of more vulnerable people (elderly, pregnant women, infants, those with certain medical conditions, those who have to work outdoors/in ceilings/on roofs all day, etc) to cope with them.
It might be fine if you're healthy and sitting inside an office all day but that's not always the case if you're in one of those categories.

Many people often refer to heatwaves as a silent killer because the deaths they cause don't grab anywhere near as much media attention as the more dramatic weather events like floods, TC's and fires.
But in reality, heatwaves are one of the biggest killers of all weather hazards.

The Black Saturday bushfires in VIC in 2009 are often quoted as an example. The fires themselves killed 173 people but the prolonged extreme heatwave leading up to and during the fires, claimed 374 lives.

37.5C max today just past 1500hrs.
Natures heater gonabget cranking next few days, expecting 40C+ around here. Bit of rain on the cards Sunday to GFS & AccessG scenarios, sure hope so.
All this rain lately sent the grass growing mad. Love the green.
You'd be feeling it a bit Ken, all this frosty weather you enjoyed last few weeks & back to real life in a sauna.
