Oh and it's "only" 22degs and, I assume, probably one of the warmest places in the country. So I would think Bolton would be unlikely to make it's way to 24.
I've heard the figure of 10% being banded around, but I think that if it is hot and sunny too then maybe you need to take into account the effects of dehydration and over heating so maybe a little less than that.
It also depends on the swimmer. It doesn't make much difference with me as I have good form without a wetsuit, and the wetsuit tends to make my form worse as I have too much bouyancy.
My river was 24.5 degrees on Thursday. Rivers are generally thought to be cooler than lakes so I don't think you can make generalisations across the country.
How much a wetsuit saves depends on the swimmer, their technique, how good the wetsuit is and how well it fits, how flexible the arms are etc. I swim 3.8K open water about 15 minutes quicker in a wetsuit than without so with a wettie im about 20% quicker. Im probably a more extreme case.
My advice to anyone would be don't rely on a wetsuit or training with a pull-buoy, ive said this to Seren a number of times. We all have time to learn how to improve our technique, relying on a pull-buoy is like someone saying they have to stop to eat on the bike, sort it out! You only have to do a very gentle flutter kick to keep the legs up.
I cant understand the concern over Ironman races being sanctioned non wetsuit but it will be what it is, you've still 2.20 to complete the swim which is loads of time.
It does depend on the person. My times aren't too much different with or without a wetsuit and in fact seem to be a bit quicker without the added restriction of a wetsuit. Like caz I have a certain amount of natural buoyancy and often find my feet kicking thin air instead of water with a wetsuit!

Good point. My technique isn't bad and I have a bottom end wetsuit that does restrict my arms a little.
I shall dip my toe tomorrow and make the decision. It'll be fun to do a non-wetsuit though! Really enjoyed my session on Thursday without
