Sunday: Boat dives from Simon’s Town jetty at 10.00 and 12.00, likely to Roman Rock (suitable for Open Water divers)
The weekend looks good for diving. We’ll be boat diving on Sunday. If you want to join us, you know what to do!

Turtles
It’s that time of year when turtle hatchlings get caught up in currents that bring them to Western Cape shores, where it’s too cold for them to survive. If you find one on the beach, please keep it dry and warm, and get it to the Two Oceans Aquarium as soon as possible. Read more about what to do on the aquarium blog here, and here.
Saturday: Boat or shore dives in the morning (early); night dive at Simon’s Town jetty at 7.00 pm
Its been a while since I have seen Muizenberg this clean, not that I go there all that often, but I do think we are going to have really good visibility in False Bay by Saturday and plan to start really early. At this point I have yet to decide on whether to shore dive or boat dive but will make that decision early tomorrow, so please text me your preference.

Diversnight!
Diversnight takes place on Saturday evening. We will be diving off the jetty in Simon’s Town (note change of location), meeting at 7.00 pm. We need to be in the water at the hour of 8.16 pm (2016!) for our efforts to count towards the official Diversnight aims of, uh, night diving around the world at the same time. There’s a facebook event here, and the official event page here.
Please let me know by 5 pm tomorrow if you’re coming so that I can give the jettymaster the approximate number of divers to expect. If you need any gear, you need to tell me by tomorrow as well please.
Sunday: Early morning double tank dive, location to be confirmed
Conditions last weekend were pretty good. Not much wind or swell and decent visibility. The wind and swell for the weekend ahead look great with very little of either. False Bay, on the other hand, looks a little messy from some humping south easterly wind today.
False Bay this morning
The wind dies tomorrow and stays away for the weekend. I don’t doubt that both False Bay and the Atlantic will offer decent diving if you take the time to check before you choose. I plan to launch on Sunday as early as possible for a double tank dive somewhere clean. I have family arriving at midday from abroad and want to be done by then. If you are up for a early dive let me know and I will add you to the list.
Great news
The Shark Spotters mobile app is available – search for Shark Spotters in the Apple app store or Google Play store and download it for free!
The weather for warm, sunny diving is here – almost! As I’m sure you noticed, we had a day or two of temperatures in the high twenties which is my kind of weather. False Bay has been pleasant this week, with some visibility and not much swell to go with the sunny days. It won’t be quite that warm this weekend but conditions will definitely be worth diving.
View north from Long Beach, Simon’s Town
We will shore dive at Long Beachon Saturday and launch for boat dives from the Simon’s Town jettyon Sunday. Both boat dives will be to a maximum depth of 18 metres as they will be first boat dives for a few students. Sites will be chosen on the day.
Out and about
Don’t forget that the crowdfunded Shark Spotters mobile beach safety app will be launched on Thursday 13 October with music (The Rudimentals) and comedy (Rob van Vuuren) at the Earth Fair food market. It should be good fun, and it’s a good cause. Book your tickets here!
Shark Spotters have been keeping bathers and surfers safe, and providing groundbreaking research on Cape Town’s white sharks, for over 10 years. They are currently developing a smartphone app that will provide information on sightings of sharks and other marine life, sea conditions, and other information pertinent to the Shark Spotters program.
Sunday: Boat dives from Simon’s Town jetty at 10.00 to the wreck of the Brunswick and 12.30, site to be determined on the day

The cold front seems to have passed by and the second one that was meant to arrive tomorrow seems now to be giving us a miss. We had 40 mm of rain at home on Thursday, for which we are grateful. The break in the weather means there is a good chance some diving might happen this weekend!
I am going to shore dive on Saturday at Long Beach and launch on Sunday, the first dive being to the Brunswick, meeting on the jetty in Simon’s Town at 10.00am. The second dive will be at 12.30, the location weather and viz dependent.
If you want to dive, let me know!
Support Shark Spotters
Don’t forget to donate to help the Shark Spotters complete their beach info smartphone app! Also, there’s an auction and comedy evening (with Nik Rabinowitz!) at the Two Oceans Aquarium on Wednesday 27 July, also in aid of Shark Spotters’ research. There’s more information about the event here.
I know we are barely past the halfway mark of winter, but the last few warm and pleasant days have got me wishing summer was here.
Some swell and lots of south easterly wind are in the forecast for Saturday, so Sunday will be the better option for diving. We will aim for a later start to see how well False Bay fares during Saturday’s onslaught. If we decide to launch the boat it will be from the Simon’s Town Jetty at 9.30 and 12.00 and the most likely sites will be Photographer’s Reef and Roman Rock.
If the conditions aren’t boat-worthy on Sunday, we’ll shore dive at Long Beach.
An app for beach lovers
The Shark Spotters centre at Muizenberg
Shark Spotters, who do pioneering beach safety work and shark research in Cape Town, are crowdfunding a mobile app which will provide information on beach and surf conditions, shark and other marine animal sightings, and whether the Fish Hoek exclusion net is currently deployed. The app will be available free of charge. Watch this video for more information about the app, and give your support by donating here!
A day early in April was the date for the annual Freedom Swim, a 7.5 kilometre open ocean cold water swim from Murray’s Bay harbour on Robben Island to Big Bay near Blouberg. As we have in several previous years, we provided boat support for a swimmer.
This entails providing a straight course for the swimmer so as to minimise the distance swum, and keeping an eye on them to ensure that they don’t get too cold or show any other symptoms of hypothermia or distress. It requires communication with race control by radio, and a bit of boat and swimmer dodging in the early stages of the race when the water is thick with activity.

Table Mountain
There was a 3.5 metre swell on the day, which made the ride out to the island a bit bumpy. As soon as we were in the shelter of the island, however, the sea was flattened as the swell diverted around the island. The water remained calm until we got quite close to shore, at which point the swell picked up. The final stretch from the rocks at Big Bay to the beach must have been very hairy for the swimmers!
Our swimmer, Maryna, swam in a wetsuit. She was part of the Lighthouse Swim relay team we supported last year. The water was relatively warm (13-16 degrees) clear at the island, and we could see kelp and quite far down into the sea. Great red streaks of water, probably an algae bloom, were filled with sea jellies (which stung Maryna, but she continued strongly). These were replaced by murky green water close to the shore, where the swell had lifted the sand particles into the water column.
It was a good day out, and always a pleasure to see Table Mountain in its majesty from the water.
It’s not uncommon to come across marine wildlife – seabirds, seals, turtles – apparently in distress. This is not always the case, so before you mount a complex and dangerous rescue mission, or try to provide help where none is needed, it may be wise to get an expert on the telephone to help you determine whether it really is necessary. Fortunately there is a range of 24-hour wildlife hotlines to choose from, depending on what species you are dealing with.
Seals
Bull seal with plastic around his neck, in Hout Bay
Seals with plastic or fishing line around their necks should be reported to the Two Oceans Aquarium (if the seal was spotted around Cape Town harbour or the Waterfront), or, more generally to the SPCA Wildlife Unit on +27 (0) 21 700 4158/4159, or +27 (0) 83 326 1604 after hours and on weekends. Unfortunately the odds are your seal is probably not going to get the help it needs if it isn’t in the port of Cape Town or at the Waterfront; this doesn’t mean you shouldn’t do your darndest to advocate on its behalf.
You can help to deal with this problem at its source by retrieving any loops of plastic that you see floating in the water when you’re on a boat. Hout Bay harbour is a particular cesspit of plastic pollution, and with a nearby seal colony it’s a recipe for disaster. Cutting through any closed loops on plastic items (such as beer can holders) that you recycle or dispose of yourself also ensures that should the plastic end up in the wild, it won’t entangle an animal.
Seals found lying on the beach are usually not in trouble. Juvenile seals may rest for long periods – a couple of days at a time – on shore, and the most important thing to do is not to disturb them. They don’t need to be kept wet, they don’t need to be fed, and they can inflict a nasty bite. Encourage other members of the public to give the animal a wide berth, particularly if they have dogs. Lead by example. If the animal appears visibly unwell (fitting, for example) or is bleeding, then call the SPCA Wildlife Unit for a chat about what course of action is best.
Seabirds
Seabirds are most often found entangled in fishing line or plastic, pierced by fishing hooks, or, in the event of an oil spill, with oiled feathers. It is important to get help if possible, particularly for oiled birds.
SANCCOB has a 24 hour rescue centre which can be reached on +27 (0)21 557 6155 or +27 (0) 78 638 3731 (after hours & weekends). Their website provides the following advice to would-be seabird rescuers:
What to do when you have found an injured/sick/oiled seabird:
If you are unable to handle the seabird, SANCCOB will send out a unit to collect the bird.
If you approach any seabird, please approach with care. Some seabirds such as Cape Gannets and African Penguins have sharp beaks.
Have with you a towel, or blanket and wear protection over your hands and eyes. Use a towel/blanket to throw over the bird to catch it, ensuring that the bird is able to breathe.
If you have a large box ensure that there are holes for air before you place the injured/sick marine bird.
During the autumn and winter months, juvenile and sub-adult sea turtles sometimes strand on Western Cape beaches. These animals are often shocked by the cold and in poor shape – they do not typically occur in Cape waters but are washed down in eddies of the Agulhas current.
Do not put the turtle back in the sea or into water. It is probably weak, dehydrated and hypothermic, and is likely to drown. Keep it dry, and call the Two Oceans Aquarium for further instructions and assistance. The aquarium rehabilitates and releases the turtles in warmer water when they are healthy.
The City of Cape Town would like ocean users to report whale carcasses before they end up on the beach. This is mostly for public safety and resource allocation purposes, but if we can do anything to keep a whale carcass out at sea (or on a secluded non-swimming beach), it serves a conservation purpose as well. There’s a phone number you can use to do this – read more here.
If you come across a current or imminent live whale or dolphin stranding, contact the NSRI on +27 (0) 21 449 3500 immediately. They will activate the relevant authorities. Try to bear in mind that these events often do not end well for the animals concerned, as they are often sick or disoriented and impossible to assist. Be a help, not a hindrance, and obey whatever instructions you are given by the NSRI, SanParks, or whoever comes to take charge.
A free-swimming but entangled whale should be immediately reported to the NSRI as well – they will activate the South African Whale Disentanglement Network. Do not attempt to assist the whale yourself – this could be fatal for you (not the whale) – rather make a note of the direction it is swimming, and its precise location, and whatever other helpful information you can provide. Whale entanglements seem to be increasing in frequency around False Bay in particular, as more experimental fisheries are approved. (If this worries you, you could write a letter to DAFF about it.)
