## Conditions at M&K Reef

M&K Reef is open to the sea from the **SE–SSW**, so waves build there when the wind blows from those directions. Land shelters it from the SW–WSW, WNW–ESE.

Over the next 7 days it's good or better on Sun. Thu, Fri and Sat are only a trend so far.

When it's rough here, try [The Steps](https://scubaforecast.com/scuba-diving-weather/australia/new-south-wales/sydney/the-steps) (2.1 km, sheltered from the SSE–SSW).

The water is warm to about 32 m.
