Sufficient exposure protection will vary from person to person, the above recommendations are a guide on where to start. Summer short suits 3mm thickness is usually enough, for full suits
in the Spring 5mm or up to 7mm may be needed. Another option is to where a shorty under a full suit. 5mm Full suits are usually OK for the Autumn as the water is warmer than the spring. A couple of
points....if you are bring a drysuit you can usually wear these without overheating from November through to May - membrane or trilaminate recommended. For neoprene drysuits use is recommended only from December through until March to avoid overheating.
Whatever the exposure protection you bring with you remember that a hood can make a huge difference in the cooler months (also protection for the head in overhead environments!) and in the warmer months a skin suit or lycra body suit can protect you from stings in midwater from various plankton or stuff that other divers
have inadvertently stirred up! If you are tec diving with us remember that the long dive times usually between 1 and 2 hours will require more exposure protection than the average recreational dive. Temperature differential at depth is never more than a couple of degrees, even at trimix depths!
