Considerations for Melbourne Dive Site Selection
Melbourne Wind Direction and Strength
- Low Northerly Winds of 5-10 knots will make snorkelling both inside the bay and out pleasurable.
- High Northerly Winds exceeding 15 knots will usually cause the bay to be quite rough.
- Southerly Winds of up to 15-20 knots won't affect the bay too badly, but will generate quite a large swell outside the heads and on the back beaches.
Melbourne Tides and Tidal Streams/Flows
- Tides and Tidal Streams/Flows are strongest near Port Phillip Heads while the top (Melbourne) end of the bay is less prone to strong currents.
- Tidal Currents are extremely strong near bay openings (Flinders, Point Nepean and Point Lonsdale) and are best dived at slack water (the period in which there is little to no tidal activity). See Diving in Melbourne Currents.
- Back Beaches (or the Surf Beaches) are prone to rip currents where the surface water will be turbid, foamy, discoloured and generally moving out seaward. See Diving the Back Beaches.
- Tide times can be checked online, or with your local dive shop. See Weather, Tides, Conditions etc..
Melbourne Conditions Through The Year
- November–March: (Summer) Has the warmest waters, but visibility may be compromised with plankton growth.
- April–July: Has the best visibility due to low plankton growth, but the water temperature also drops considerably.
- August–October: (Winter) May have challenging weather conditions above water, but good and relatively clear diving conditions below. Rains wash out dirt and materials into bay dive site that affect visibility and conditions usually take about 2 days to return to previous visibility levels.
If the dive site conditions cause any doubt, use your best judgement and avoid diving in areas that are suspect. You can always come back another day.
