My personal coldest wet dive was 32 degrees F in a 1/4" farmer john suit with hood and gloves.
A friend of mine did a dive in a 1/4" farmer john into 10 degrees F.
It was a very short and shallow dive as it was in a brine tank and was a simple repair job. Using the wet suit got the job done in minutes rather than taking the few hours to get the dry gear. The customer said that the down time was costing him about $4000/hour. The fast repair saved more as it prevented the need for a shutdown/startup that cost even more.
