Race Day Weather

Average Temperature	18°C / 64°F
Humidity	68%
Wind	12 km/h
Rain Chance	15%
Typical Conditions	July is Cairns' dry-season tropical winter - the single most comfortable racing month of the year. The 5:45am start sees a mild ~17-18°C (64°F) dawn, warming toward ~26°C (79°F) by late morning. Humidity sits around 65-70%, low for the tropics, with rainfall a near non-issue at ~15% chance. The catch is UV: the tropical sun is intense once it clears the horizon, even when air temperature feels pleasant.

What to Prepare: Race in shorts and a singlet - the dawn start is cool but you will warm fast. Apply high-SPF sunscreen before the gun and reapply if you are a slower finisher, since UV climbs sharply after 8am. Carry or plan fluid early; the heat builds over the back laps. Check our Weather Score tool to gauge conditions against your goal pace.

Wind Impact on Race Day

Wind at 12 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

Frequently Asked Questions

When and where is the 2026 Cairns Marathon?

The 7Cairns Marathon Festival is held on Sunday, July 12, 2026, with the full marathon starting at 5:45am from Fogarty Park on the Cairns Esplanade. The festival also includes a half marathon plus 10km, 5km and 2km events across the morning.

Is the Cairns Marathon course flat and good for a PB?

Yes. The marathon is a flat, four-lap loop along the Esplanade waterfront with only about 40m of total elevation gain. The AIMS/World Athletics certified course is one of Australia's flattest, making it a strong choice for a personal best.

Is the Cairns Marathon a Boston-qualifying race?

Yes - the course is AIMS/World Athletics certified, so a qualifying time run here is valid for Boston Marathon entry. Check the standard for your age and gender with our Boston Qualifying calculator before you set a target.

How do I register, and is it sold out?

Entries open through the official site at cairnsmarathon.com.au, with a fee schedule that steps from AUD 200 (super-early-bird) up to AUD 260 (late entry, closing 11 July 2026). As of research date the general full-marathon places for 2026 are sold out, but charity places remain available through partner charities such as Ronald McDonald House Charities North Australia.

What is the time limit and field size?

The full marathon has a cutoff of about 5 hours 45 minutes, comfortable for most runners. It is a mid-sized event with a marathon field of roughly 390 finishers, so the start is relaxed rather than congested.

What is the weather like, and what should I wear?

July is Cairns' dry-season winter - the most comfortable racing month, with a mild ~18°C dawn start warming to ~26°C and low humidity. Wear shorts and a singlet, and prioritise high-SPF sunscreen; the tropical UV is strong once the sun is up despite the pleasant air temperature.

How do I get to Cairns for the race?

Cairns Airport (CNS) has direct domestic flights from Sydney, Melbourne and Brisbane, plus some international links across Asia-Pacific. The Esplanade course, Fogarty Park start and most accommodation sit within a walkable central strip, so no car is needed on race weekend.
