April has warm daytime averages followed by cooler nights. A light racing outfit and a removable layer for waiting cover the difference between those conditions. Average daily highs are 25.3°C and overnight lows 16.1°C. Average precipitation totals about 84 mm over the whole month. Rain preparation is sensible, but the total does not give the chance or timing of rain during the race. These are historical regional averages, not a forecast or race-hour temperatures; the coast, hills and start line may differ.
