Coral Bay weather in brief
Summers are very hot and winters are mild. The climate figures below come from the Bureau of Meteorology (BoM) station at Learmonth Airport, station 005007, at 22.24 degrees south and 114.10 degrees east, 5 m above sea level. Learmonth is a regional comparison station. It is not a measurement taken in Coral Bay. Treat the values as a guide to the typical season, not as a forecast.
The figures are long-term monthly averages: the mean of the daily maximum and minimum temperatures and the mean monthly rainfall. Temperature series run from 1975 to 2026 and rainfall from 1945 to 2026, with some gaps. They are not a record for 2026 alone. This site is independent and is not the Bureau of Meteorology or any official weather service.

The BoM table also gives mean daily wind run, for example 489 km per day in October, 532 km per day in December and 310 km per day in May. Those are daily totals, not gusts, and they do not describe swimming or boating conditions at a particular beach on a particular day.

Best time to visit Coral Bay
There is no single best month for everything. The answer depends on what you want to do.
| What you want | Season | Source and caveat |
|---|---|---|
| Cooler days on land | June to August | Maximums of 24.5 to 26.6 °C in the BoM table |
| Manta rays | All year | An operator describes mantas in the waters off Coral Bay all year. That is not a promise of a sighting on a given day. |
| Whale sharks | March to August across Ningaloo | DBCA season for the whole reef. A Coral Bay operator sells its whale shark trip from April to June. |
| Humpback whales | June to November across Ningaloo | DBCA season. One Coral Bay operator sells whale trips from July to September. |
| Turtle hatchlings | February and March | DBCA names these months for the Ningaloo coast. A sighting at any one beach is not guaranteed. |
This table is a synthesis of the sources above, not an official recommendation. For details on each animal and the rules for tours, see the guides on manta rays and whale sharks.
Heat and cyclone season
DBCA gives the cyclone season as November to April and notes strong summer heat, especially from December to April. That is not a general ban on summer travel, but it affects how you plan driving, walking and time on the water. The figures show December to March maximums of 36.6 to 38.1 °C.
Cyclones can damage roads and campgrounds. Further north, DBCA reports campgrounds closed after cyclone damage in 2026. The Ningaloo guide covers the reef north of Coral Bay.
Use shade, water and sun protection in every season. October is dry, with a mean rainfall of 1.4 mm, but the mean maximum is already 33.0 °C.
