Best time to visit Whyalla

October is the best month in Whyalla, scoring 95 out of 100, with January the weakest at 74. The 21-point spread means timing is worth planning around without being decisive. 6 of the twelve months sit within ten points of the best, so there is more than one right answer.

There is a real wet season here. May to August carry the rain — up to 7 wet days in a month — while January, February, March, October and December drop as low as 2. That 5-day gap is the biggest single difference between a good month and a bad one in Whyalla, and it moves further than the temperature does.
