Geraldton is mainly a cooling job. Summers average 32 to 33 degrees with some days over 40, and at Geraldton Airport February runs hotter than January. Winters are mild, so heating is lighter work, and near the surf, salt on the outdoor unit is the other thing to plan for.

Geraldton's heating and cooling facts

Temperatures

Wikipedia's table for Geraldton Airport at Moonyoonooka (1981 to 2020 normals, with temperatures from Weatherzone rather than the Bureau of Meteorology) gives a mean maximum of 31.6 degrees in January and 32.8 in February, and a July mean minimum of 9.5. The airport's record high is 49.3 degrees.

Humidity

Average 3 pm humidity at the airport is 44% in January and 56% in July.

Coast and inland

Afternoon sea breezes cool the coastal suburbs, which generally run cooler in summer than the inland ones. In winter the wind swings mainly easterly, off the land.

Climate zone

NCC 2016 puts Geraldton in zone 5, warm temperate, like Perth. Carnarvon to the north is zone 3, and inland Northam and Meekatharra are zone 4.

Salt

The GAA's corrosion guide rates the first 200 m back from rough seas and surf beaches as C5, 200 m to 1 km as C4, and 1 to 10 km along ocean fronts with breaking surf and salt spray as C3.

Housing and gas

At the 2021 Census, 86.3% of the City of Greater Geraldton's occupied homes were separate houses, 10.6% townhouses or semis and 1.6% apartments, and 29.6% were rented. ATCO's gas distribution systems serve Geraldton.

The jobs that come up most in Geraldton

Cooling first. Split systems for the rooms you use and ducted reverse cycle for whole houses make sense here, sized for February afternoons and the odd 40-degree day. Inland suburbs carry a bigger load than the coast, so the quote should reflect where you live.

Evaporative, case by case. CHOICE rates evaporative as most effective in hot, dry climates with low humidity. At 44% in January, Geraldton's afternoons are a little more humid than Perth Metro's 39%, so get an installer's honest view for your suburb.

Servicing near the surf. Salt works on coils and casings within reach of the ocean. See air conditioning service in Geraldton.

Light heating. A reverse cycle system handles mild July nights, and gas is on the network if you'd rather.

Who does the work

WA asks for two things on a new install: an ARC licence for whoever handles the refrigerant, and a licensed electrical contractor, with an EC number on their business materials, for the switchboard and fixed wiring. The WA licence page explains how to check both.

Each job is shown to licence-checked local installers near Geraldton who specialise in it, where we have them. If no one near Geraldton takes it within 48 hours, installers elsewhere in Western Australia may see it too. The installer who takes yours is the only one given your contact details.

What we'd do

What we'd do in Geraldton

We'd size the cooling for February, not January, and tell the installer whether we're on the coast or inland, because the load differs. Within a kilometre or so of the surf, we'd want coastal coil protection and a yearly service that includes the outdoor unit. Heating we'd keep simple: the reverse cycle system we were already putting in.

Questions people ask

Why does February matter more than January in Geraldton?
At Geraldton Airport, February's mean maximum (32.8 degrees) is higher than January's (31.6). It's the month to size and service for.
Do I need heating in Geraldton?
Some. July nights average 9.5 degrees at the airport, and the record low there is just under 0 degrees. A reverse cycle system usually covers it.
Does salt from the ocean reach inland suburbs?
It can. The GAA rates up to 10 km back from ocean fronts with breaking surf and salt spray as C3. The closer you are, the more it matters. Our coastal homes guide explains what to ask.
Is evaporative cooling worth it in Geraldton?
On dry days it can work, but it only cools and loses ground as humidity rises. Our evaporative or refrigerated guide helps you decide.
