Weather in Rockhampton in May

Prime time. May is about as good as Rockhampton gets. Highs average 26.2 °C, lows 15.9 °C, and rain falls on 6 days — nothing in the month is working against you.

May ranks 3 of 12 in Rockhampton. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest May day reached 32.9 °C and the coldest night fell to 7.2 °C, and the wettest single day dropped 42 mm — roughly 131% of the month's rain in one day.

May is moderately variable: 8 mm in the driest year against 119 mm in the wettest, around an average of 32 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 10 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 70%.

How May sits in the year

The month is on the way down: 2.6 °C cooler than April, with June dropping another 2.4 °C. The first week and the last are not the same trip.

Daylight in May

May sits at the dark end of Rockhampton's year — 11 hours of daylight against 13.6 at midsummer, losing 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 24.8 °C in May — warm enough to stay in as long as you like. The sea peaks at 28 °C in February and bottoms out at 21.3 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

May in Rockhampton versus nearby

If Rockhampton is one option among several, the nearby comparison is worth making. Bundaberg is close enough to be a coin toss — 2.1 °C cooler, 5 days more rain. Mackay is close enough to be a coin toss — 2 °C cooler, 5 days more rain.

So: May is effectively as good as it gets here — 5 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
