How the day is laid out
The swim is held in a bay. An average of 29 °C is warm. Wetsuit use is commonly restricted above this point, and the swim becomes a question of heat more than of cold.
The bike leg is labelled flat.
The run is labelled flat, over 2 laps.
A flat bike followed by a flat run is the most predictable combination on the calendar. It removes climbing and the descents that come with it, so power output stays constant for the whole bike leg and wind becomes the main variable.
Expect air between 25 °C and 31 °C on race day. A spread of 6 degrees across the day matters as much as the peak, because what you wear at the swim exit is rarely what you want at the far end of the bike.
