Tyre sliding around under straight line acceleration.
Discussion
So as per topic, getting a bit more comfortable with my bike (2012 CBR600F) and the tyre slides out under hard acceleration. Not flat out acceleration, just anything a bit brisk.
Tyres are in good condition, and are Bridgestone S20 evo's so they shouldn't be a problem. I'm guessing it's the walley behind the controls (me)?
However it just seems a bit odd as I really don't feel like I'm accelerating that harshly, and it really seems to spin out quite a bit. Any other possibilities or I'm just an idiot?
Tyre pressure I should add is the correct manual (and bridgestone) stated 36/42. However I do live in Gibraltar where it's 30+ degrees and road temps are hot. Could this be making that temp too much perhaps?

You'll be hard pushed to ever get a rear to spin in dry on a straight road
You bike has circa 100bhp. If its its revving up look at other area's like clutch slip etc
Tyre pressure at 32-42 wont make that much of a difference as mentioned earlier ideal pressure will get it handling better
Unless the ground is loose, wet or there is another underlying issue I would be very surprised that its wheel spin (Not doubting you but as you said you are new to it)

Girlfriend was walking past (hadn't seen her and wasn't showing off lol) and literally messaged me straight away saying that I drove past her fast and the back was swinging from side to side
And yeah, normal tarmac and not aware of any loose gravel. Clutch was totally out already. I had gone alongside a bus so was in first going slowly, clutch out totally, once I got past it I began to give it some revs (quite a lot, but nothing crazy) and that happened.
I'll drop it down sometime and take it for a spin, and then check pressures once warm. I'm guessing for road use I'd like them to be around that 36/42 but hot?

Also thanks for all the help! I lurk this forum ALL the time since I got my bike but never post. I'll get some pics up in the pic a day thread etc to say hi
Edit: I should add that I mentioned this to a friend and he said that there's building works alongisde where I was so it's possibly it was dusty etc and I didn't notice. Just never had this before until summer hit, and suddenly it seems to happen to me every few days.

Measure your pressures cold as they will always vary when warm, use 36 for the rear tyre, I lived abroad for quite a few years and ran lower rear pressures because of the very slippery road surfaces everywhere, and didn't die once, or have any unintentional wheelspin, on a 135bhp bike, never mind a 95bhp 600

Hey MCN says 101bhp haha. Gotta be triple digits haha. Thanks though will definitely try lower pressures. Something is wrong.
Standard tyre pressures shouldn't make that kind of difference until the the tyre gets hot, even at 30deg.
So either the roads are slippery or something is broken.
I suggest you check your rear damping.
A lack of damping will result in the tyre bouncing and losing traction.

Having owned and ridden the same bike, on 36, 42 tyre pressures, in far war warmer conditions than the OP's, I've never experienced the poblems he's highlighted. I would say you can rule out tyre pressures as the cause!
Other than dust on the road, the only thing that caused wheelspin for me, was riding over those tarmac snakes that seem to be the norm for repairing cracked road surfaces, in hotter climes!
