Wetsuit outlook
Will you need a wetsuit at Chester Triathlon?
Water temperature at river in June has typically been 12.4°C, ranging from 10.5°C to 13.4°C in eight of every ten years. Against British Triathlon's thresholds for this race's 1500m swim, that means:
Wetsuit mandatory
Below 14°C a wetsuit is compulsory for a 1500m swim under rule 4.2(a).

What the organiser says
A full 1500m swim needs water above 13°C; below 13°C the swim is shortened, and below 11°C the event converts to a duathlon (5km run/40km bike/10km run).
Estimated from air-temperature history — no direct measurement of this water exists, and small, shallow venues tend to run a degree or two warmer than shown. The official temperature is taken an hour before the start, and only that reading decides the rule on the day.
Transitions
Transition is at Grosvenor Park, opening 05:45 on race morning; bikes are racked 05:45-09:00 with sequential (unmarked) racking.
