Same here. Currently getting temps in the 20s and the winds have dried everything out nicely, but the big chill will be back for August.

Thursday 25th of July 1p.m. Overcast and windy. Failed to reach 23C forecast yest 
22.2 / 25.9kph NE, Hg 45%, 17.9C / 64.2F top of 21C / 70F. Possible late shower.
Moon is 82.1%
This is summer for parts of the northern hemisphere right now.
The searing heat has claimed many lives, from Crete to California, and New Delhi to Mecca, as temperature records have tumbled over the past month.
Sunday July 21 was the hottest day since at least 1940, according to the Copernicus Climate Change Service.
But while Greece shuts the Acropolis and people suffer third-degree burns from footpaths in Las Vegas, it's all blankets and heaters in parts of Australia.
We're having a frosty winter, with a few Antarctic polar blasts, and many Australians from chillier regions will seek a temporary reprieve from the cold and head overseas for a "Eurosummer" or US vacay in July and August.
But the extreme temperature change between take off and landing is a huge test for the body, so preparing ahead of your trip may help you to stay safe in the heat.
That's a huge shock to the body, says Harry Brown, a post-doctoral researcher at the University of Canberra who specialises in seasonal acclimatisation.
Coming from winter, you will have a low tolerance to heat, and the physiological adaptations the body uses to stay cool, such as sweating more profusely, won't instantly activate when you touch down.
"It means a normal task like just a bit of sightseeing in Italy will increase our heart rate a lot more than if we were just walking around Canberra," Dr Brown says.
While it's a myth your blood gets thinner when you swap cold weather for hot, your blood vessels do need to change size to cope with the temperature change.
Instead of constricting to minimise heat loss, they dilate, bringing more blood to the skin and releasing heat.
Humans can acclimatise — we do it every time the season changes — but it normally happens slowly over several months.
We can, however, build up our tolerance more quickly through repeat exposures to heat, and safely pushing ourselves to increase our physical activity, which raises our core temperature and blood flow to the skin.
It's a bit like what the Olympians have been doing in preparation for Paris.
"This constant disruption to our core temperature will prompt the body do things differently," Dr Brown says.
Special heat adaptions will be "turned on" and allow us to endure high temperatures with less risk of heat stroke and death.
The key signs someone is acclimatised include:
having a lower heart rate and core temperature when active
improved sweating (earlier onset of sweating, loss of more millilitres per hour, and reduced loss of electrolytes)
a higher volume of blood plasma, meaning the heart doesn't need to work as hard to pump blood around the body.
But Dr Brown says it can take up to three months for someone to fully acclimatise if they aren't doing a specific regime for heat acclimatisation.
And even if you're a physically fit person, meaning you're more heat tolerant to begin with, acclimatisation can still take 14 days.
By then, it's possible your Euro trip will be coming to an end.
When my best friend moved to Queensland from New South Wales (1988) it took her and hubby 14yrs to fully acclimate. The children born in QLD needed heating in winter while my friends sat outside melting in the winter heat lol

Heading off for 'Eurosummer'? How to help your body adapt to the heat when you travel

Making the switch from cold to hot
If you live in southern Australia and travel to southern Europe or some parts of the US around this time of year, you can expect up to a 30-degree difference in maximum daily temperature.That's a huge shock to the body, says Harry Brown, a post-doctoral researcher at the University of Canberra who specialises in seasonal acclimatisation.
Coming from winter, you will have a low tolerance to heat, and the physiological adaptations the body uses to stay cool, such as sweating more profusely, won't instantly activate when you touch down.
