Weather in Geraldton in June

Prime time. If you get to pick your dates, June is the one. Highs average 20.7 °C, lows 17.6 °C, and rain falls on 9 days — nothing in the month is working against you.

June ranks 10 of 12 — near the bottom of Geraldton's year. January is the month that works, and the swing between the two is 19 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: June is the weakest month of Geraldton's year and it is still a perfectly good one. The downside here is small.

Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average June reaches 30 °C; the day barely swings — 3.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 25.2 °C and the coldest night fell to 13.5 °C, and the wettest single day dropped 39 mm — roughly 56% of the month's rain in one day.

June is moderately variable: 8 mm in the driest year against 145 mm in the wettest, around an average of 70 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind sits around 20.1 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 67%.

How June sits in the year

Temperatures hold steady either side: 22.4 °C in May, 20.7 here, 19.4 in July. Nothing about the timing within the month matters much.

Daylight in June

June sits at the dark end of Geraldton's year — 10.3 hours of daylight against 14 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 22.3 °C in June — comfortable for a proper swim. The sea peaks at 23.7 °C in March and bottoms out at 19.9 °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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

June in Geraldton versus nearby

If Geraldton is one option among several, the nearby comparison is worth making. Perth is the weaker option in June — within a degree on temperature, 3 days more rain. Bunbury is the weaker option in June — 2.8 °C cooler, 6 days more rain.

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