It reaches its highest monthly mean in July, at 2.79 mm/day, so rain preparation is especially relevant for travel then.

Best Travel Time Guide for Adelaide, Australia: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, July is the relevant option, with a monthly mean temperature of 11.1 °C; this is not a daytime maximum and cannot describe every day. If lower average rainfall is the main criterion, March records 0.63 mm/day of mean daily rainfall. That average does not guarantee rain-free days or indicate rain frequency, so keep plans flexible. Rain preparation is worth considering for July, when mean daily rainfall reaches 2.79 mm/day. For daylight outdoor planning, mean daily sunshine is highest in December at 12.06 hours/day, and lowest in June at 7.33 hours/day. These are separate criteria rather than a combined best-time ranking; sunshine duration does not measure day length or promise clear weather.
