It used to to 40+ degrees in Sydney once or twice a year... but with relatively low humidity. So some days it would feel like a fan forced oven outside. Temps higher than 37-38, are another thing altogether...
I suppose I'm accustomed to hot weather (I relish it and it's my favourite time to go out for a ride

). So this climate seems milder for me.
EDIT: Actually Australians are bombarded with scare-campaigns about sun tanning and the risks of getting skin cancer (cause I think OZ has once of the highest rates of skin cancer in the world). They'll say "there's no such thing as a healthy tan", and that you need to apply suncream, wear a shirt, a hat, and sunglasses. BUT WE NEED SOME EXPOSURE TO SUNLIGHT! I reckon that the 100% humidity which the tropics/equator experiences is far worse than high temperatures...
But I disgress...
It's been ages since I went for a sunbake here in Tenerife... I think I might have to go this week down to El Lago and soak up some rays.
You came for the sunshine - I don't know why you'd whinge about it now!?
