Best time to visit Mount Gambier

January is the best month in Mount Gambier, scoring 91 out of 100, with July the weakest at 48. The 43-point spread means timing is worth planning around without being decisive. 5 of the twelve months sit within ten points of the best, so there is more than one right answer.

January is the warmest month at 22 °C and July the coolest at 13.2 °C — a 8.8 °C spread across the year.

There is a real wet season here. June to September carry the rain — up to 17 wet days in a month — while January to March drop as low as 5. That 12-day gap is the biggest single difference between a good month and a bad one in Mount Gambier, and it moves further than the temperature does.

The sea peaks at just 17.9 °C, which is wetsuit territory even at its warmest — a coast to look at rather than swim in. Daylight runs from 9.6 hours in winter to 14.8 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are January, February, March. The one to think twice about is July. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
