I am just curious about people SAC rates and how much they change from warm waters to cold.
I was at 17l/min while on holiday in Malta but now I seem to be hanging around 29l/min and it just seems a bit high.

Does it matter provided you know what it is?

Mine is 15 but I still plan off 20. Cold water only.

SAC after a lot of diving was at 25 on the bottom, 20 on deco. I found out quite early on that worrying about my sac put it up to 30-35. I started planning my dives for gas consumption on V planner and adding 1/3rd as reserve (even single cylinder no deco dives). Once I knew I had plenty of gas and I wasn't worrying about it then my SAC leveled out at the current figure.

I'd imagine experience can have implications on SAC rate too, so don't take it out of context. I've had a similar experience to you in that mine dropped to 17 in Malta when i was there in Feb, 15C in water. Got home, jumped to 22. After another 10 dives at home it started coming down to about 19. I always plan with 20.

I've 80+ dives. Dry suit, mostly UK diver, all seasons. ;)

12 and 13 is amazing, i can't imagine that at all. Gits.

I only got reliable sac rates on my last 30 odd dives all in cold water. It seems to be much more influenced by the stress encountered during the dive than anything else. I was changing a lot in my kit during these dives and for a while 30+ lpm was quite normal. As I'm getting grips with the kit and the last 8 dives were all around 19-20. I still plan for 25 l in ideco.

Obviously I do a eck of a lot of single cylinder diving, and my SAC is 7.5lpm, but when I throw a twinset on it goes up to 10lpm - don't know why as I feel just as comfy.

When I'm teaching PADI OW students I look into their SAC rate and if its over 20lpm I try to work with them to get it down as I think thats a little high.

world of difference in warm water, no drysuit etc
my sac rate is about 11 in the red sea.
in UK, drysuit, cold, twinset, about 17.
i used to worry about it, and was told to stop worrying and it will look after itself, they were right!

My sac seems to be hovering around 11l/min for cold water diving. Never worked it out when in warm water but it was something stupidly low but then i was diving everyday at the time. Ive found as soon as i stopped worrying after my sac and just breated normally dueing a dive it dropped massivley. I plan dives for a sac of 15, used to do it with 25 but got sick of using twins when a single 12 was more than enough

In warm, clear waters, mine is about 9. It is about 15 on 'normal' dives, but rises on deco, which is apparently unusual.

I gave up worrying about what it was, and it fell :)

Mine was about 10/12, my buddies was about double

Not sure why, and never did find out

We just put it down as "your SAC is your SAC"

I am not really worried about it, I was more curious. I have just seen a few changes to my set up and I was wondering how it compared with the experiances of others.
I carry alot of stress from work, learning a new language and new house, new country new equipment (New drysuit, wing, doubles....hell, even my torches and reals are new) so maybe in time as my bouyancy gets better and I relax a bit more I will see my rates fall.
