What the data actually tells you

Guest comfort

July keeps seated guests at 26°C in the afternoon and around 20°C after sunset — the closest Cairns gets to a ceremony that needs neither shade structures nor patio heaters.

Rain backup risk

Rain falls on roughly 1 days in July (very low risk, 22mm). A simple marquee-on-standby is usually enough.

Photography light

July gives 11.1 hours of daylight and about 8 hours of direct sun per day, so a late-afternoon ceremony puts portraits inside golden hour rather than after it.

Month to avoid

February scores 26/100 for weddings in Cairns: 31°C highs, 440mm of rain and 26°C evenings make a fully outdoor plan fragile.

Ceremony timing in July

Wedding score, factor by factor

Wedding weather is scored differently from travel weather: seated guests in formalwear tolerate a narrower band than sightseers, and the ceremony hour matters more than the daily average. Each month in Cairns is scored 0–100 on the weighting below.

FactorWeightWhat it measures
Dry conditions 38% Share of days with measurable rain — the single factor most likely to force a backup plan.
Guest comfort 27% Distance from a 22°C daytime ideal, with an extra penalty for humid heat above 24°C.
Evening temperature 20% Modelled reception-hour temperature against an 18°C ideal for an outdoor evening.
Photo light 15% Sunshine hours and daylight length, which set the length and quality of the golden hour window.

Based on long-run climate averages rather than a forecast. Plan the ceremony around the golden hour — see golden hour times for Cairns linked below.
