Weather in Griffith in August

Prime time. August is about as good as Griffith gets. Highs average 16.5 °C, lows 4.4 °C, and rain falls on 6 days — nothing in the month is working against you.

August ranks 6 of 12 in Griffith: past the worst of the year but short of April, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 16.5 °C days and 4.4 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest August day reached 28.2 °C and the coldest night fell to -2 °C, and the wettest single day dropped 26 mm — roughly 84% of the month's rain in one day.

August is moderately variable: 6 mm in the driest year against 70 mm in the wettest, around an average of 31 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How August sits in the year

The month is on the way up: 1.7 °C warmer than July, and September adds another 4.4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in August

10.8 hours of daylight, gaining 0.9 hours across the month. That is between Griffith's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 31.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Griffith versus nearby

If Griffith is one option among several, the nearby comparison is worth making. Wodonga is the weaker option in August — 2.8 °C cooler, 5 days more rain. Canberra is the weaker option in August — 3.2 °C cooler, 3 days more rain.

So: August works, with April the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
