Weather in Geraldton in January

Prime time. January is about as good as Geraldton gets. Highs average 24.7 °C, lows 21.3 °C, and rain falls on 2 days — nothing in the month is working against you.

January is the highest-scoring month of the twelve. The nearest rival is February, and the month at the other end of the year is July.

Rain falls on only 2 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

Averages flatten a month, and this one hides a few things: the day barely swings — 3.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 36.1 °C and the coldest night fell to 17.4 °C.

This is the volatile part. January rainfall has ranged from 0 mm to 36 mm across the twenty years measured — a 36 mm spread around an average of 9 mm. The average is real but almost no individual January looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind sits around 24.7 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 23.6 °C in December, 24.7 here, 25.8 in February. Nothing about the timing within the month matters much.

Daylight in January

January is at or near the longest days of Geraldton's year: 13.8 hours of daylight, losing 0.5 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 22.4 °C in January — 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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, September is the trade worth considering — 10 points weaker on weather, and materially quieter.

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

January in Geraldton versus nearby

If Geraldton is one option among several, the nearby comparison is worth making. Perth is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Bunbury is the weaker option in January — 6.3 °C warmer, the same number of rain days.

So: January is the answer for Geraldton. If it is booked out or priced out, February is the next best thing at 0 points behind, and July is the month to keep off the shortlist.
