The days are getting longer and the daytime temperatures are slowly creeping upwards… Well, on some days. Saturday looks like a better bet for False Bay with Hout Bay being an option on Sunday. The water colour off Dungeons has improved slightly today.
Tomorrow I am shore diving students at Long Beach at 10.00 am. On Saturday we will do an early False Bay double tank dive at 7.00 am. Let me know if you’d like to get wet.
As part of First Thursdays, you can attend the opening of the Birdlife Oceans of Life photographic exhibition at the South African Museum on the evening of Thursday 6 October. There’s information here (facebook) – this year’s exhibition includes a retrospective of the last few years’ best images.
Diversnight is on Saturday 7 November, so start charging your torches!
As your self-appointed education officer and fellow perpetual student, it is my duty to inform you of an upcoming MOOC on the Futurelearn platform, entitled “Monitoring the Oceans from Space“. In the five weeks of the course, which starts on 24 October, you will learn about using satellite data to monitor the health of the oceans. You will also learn how to access some of the ocean monitoring data that is collected every day about weather phenomena, icebergs, sea levels, ocean temperature, and more. If you’re into creating your own visualisations or crunching numbers yourself, this should appeal.
Sunday: shore or boat dives, depending where the viz is!
A cold front arrives tonight and will make itself felt until Saturday evening. Sunday will be best for diving. I have student dives to complete; if the inshore conditions are good, we’ll shore dive. If the visibility is only to be found further out, we’ll launch Seahorse. If you’re keen to get wet, let me know and I’ll update you on Saturday afternoon.
Sunday: late morning dives, location to be determined by the weather!
It is once again one of those weekends where diving will be best on Sunday. “But where?” is the million dollar question. Humping south easterly wind on Saturday may or may not mess up False Bay entirely, and may or may not be enough to clean the Atlantic. So it’s a Sunday diving day, and a late Saturday decision on where and what time… More vague than that I cannot be. If you’re up for this undetermined diving adventure, let me know and I’ll keep you posted about what’s happening where.
Diversnight is happening on 5 November this year (thanks CvS for the reminder)! This Norwegian night diving initiative has origins that include cake, which is all you need to know. If that’s not enough for you, read more here and here. Participation is free of charge, the more the merrier. I’ll remind you closer to the time so that you can get your torch batteries charged.
Saturday: Shore dives in Simon’s Town (only if forecast south easter does not materialise)
Sunday: Launching at 9.00 am and 11.30 am in Hout Bay or Simon’s Town
There is a good chance that diving could be good on both sides of the peninsula on Sunday. Saturday will be made unpleasant if the strong south easterly winds and predicted swell arrive, so Sunday will be the best choice for diving. (If the weather is good and wind is mild on Saturday, we will shore dive in False Bay.)
False Bay may be good if the swell does not turn as southerly as forecast, or if the south easter doesn’t quite get up to the 40 km/h in the forecast. If the wind does arrive, then Hout Bay should clean up enough for some decent conditions.
We will launch on Sunday at 9.00 am and 11.30 am, destination unknown. We will decide late on Saturday whether we will go to Hout Bay or False Bay on Sunday. Either way both dives will be suitable for Open Water divers, maximum depth 18 metres.
The toilets at the Simons Town jetty are currently closed for renovations as I understand it. They are due to be ready soon but I do not have a date. Also note that the Wharf street parking at the jetty is again a paid parking area for the season.
It may seem that given the week-long south easter we are having, it would be a simple matter to decide which side of the peninsula to dive. The picture was taken from Chapmans Peak drive today around lunchtime, and the water is not very clear – there are rocks just below the surface in the little bay below the road, but they are hardly discernible.
The water colour in False Bay is not very different but False Bay does seem to recover faster than the Atlantic coast of the peninsula. Sunday’s forecast is for gale force winds, so Saturday is the only decent diving day, but where?
Depending on tomorrow’s wind direction I will make a call late in the afternoon on whether we will launch in False Bay or out of Hout Bay. Either way it will be for dives at 10.00 am an 12.30 pm. I will have mostly Open Water students so the maximum depth will be 18 metres.
We are in a phase of semi-decent weekday diving and dodgy weekends again. We had fairly good False Bay diving during the week, but the weekend forecast is not ideal for much beyond storm chasing. Strong winds and some significant swell topped off with a dash of rain are hardly a cocktail for diving. Northerly wind is not that great for False Bay and neither is a 5 metre swell, so best you pursue some other form of activity this weekend.
One of the guys in the Underwater Cape Town facebook group reported a sighting of a john dory at A Frame this week. These fish are striking, solitary, and seldom seen. Bizarrely for such an exotic-looking fish, they are popularly served wrapped in newsprint with a side of chips. We were lucky to spot one at Long Beach a few years ago. (Go check out the video on Underwater Cape Town for a better idea of what they look like, and keep your eyes open next time you go diving!)
Talks talks talks
This Wednesday 17th is the nautical archaeology talk I mentioned in last week’s newsletter. There’s a talk on 23 August about the health of our fish stocks by scientists Colin Atwood and Jock Currie at Bellville Underwater Club – info on facebook. If you have a UCT staff or student card, you can listen to conservation photographer Thomas Peschak speaking on 21 September – info on facebook, too.
I completed the edX-hosted Sharks! MOOC, presented by Cornell University and the University of Queensland, and it was excellent. The content was clear and for me, who stupidly quit high school biology at the age of 14 for the sake of a more classical (less useful) education, filled in a large number of gaps in my understanding of sharks and rays.
