Sea temperature website

[Fly-aholic]

Dear all,
Anyone aware of an accurate sea temperature website for Muizenberg, Macassar or Strand?

Thanking everyone in advance.

Unfortanately the places you are looking for dont have a temp reading from the buoy is seem,closest is Cape point.

Thank you Lofty, will have a look.

Dankie Pieter, gaan loer.

But temp charts will most time be a computer guesstimate, not have the resolution you need for between the spots, and always be a day or two behind..but you can use it to spot the patterns and when what winds do what to the sea temps..and use that watching the wind outside to predict what is happening.

The wavescape surf report email used to have quite detailed sea temps for cape town spots, wonder if Spike still includes that information with the report?

we use Wavenet for our ship loading activities especially the wave height so it should be very accurate, sometimes the temp censor on the buoy is not working

Hi UK49,
That was my initial question to consider all the inputs for decision making. All the factors like, tide, temperature, wave height, barometer have an impact.
I have found that it is impossible to 'tick all the boxes' remotely i.e. eliminating the variables. Being an engineer, not always a good thing, I am inclined to have a certain probability of success before going on a 'mission'.
I have found that 'analysis paralysis' is very debilitating and removes the enjoyment of fishing.
There are general rules that apply to most fishing, depending on what species you are targeting.
Personally, I am OK with applying these general rules and just enjoy the time out. Every 'now and then' my analytical brain does me a 'dirty', and I embark on a mission to determine 'absolute certainty' which is non-existent.

However, by asking these type of questions the members are very helpful and will share their experiences, and from there you can derive success probability.

Coming back to the temperature issue.....this cannot be determined from sitting on the couch. However prevailing winds and tides will give you an indication.
Being originally from the Eastern Cape (Port Elizabeth) where the fishing areas lends itself to either a westerly or Easterly wind, selecting a fishing destination is much easier.
Here in Cape Town (False Bay), specific conditions apply for specific species and it has taken me, even with members willing to share information, more than 2 years of consistent fishing to have an idea of what makes False Bay tick.

As much as it goes against my analytical nature, nothing equips you better than to spend time fishing. This affords you the opportunity to have conversations with other anglers and gain the experience accordingly.
What I will say is that cob fishing in False Bay is completely different to cob fishing in the Eastern Cape, regarding water temperature, swell and preferred bait, which I am still getting accustom to.
There are really some super guys here in Cape Town to guide you and gain the knowledge. Do not be afraid to ask and approach fellow anglers on the beach, they are most willing to share.

True, but as I understand it is satellite infra red images that temperature is calculated, which should give accurate data.

The question is, what is the resoulution, every 30 meter sq, or every 1km sq?????????????

Further, the temeratur bands, every 5 or 2 Centigrade intervals??

Who knows???

Very interesting to me, how muche the temperature varies within a day.........

Check the latest SST image tab on the top right..One cant see the full size image without paid account, but one can see the thumbnails of the images and if you look for example at the last few days, there has only been one or two passes where the bay was cloud free and then even the data was very limited country wide..Most of the time the cloud free image is a computer guesstimate based on temps that could be a day or two or more old anyway..Depends, summer time there will be less cloud and more regular images for the computer to make better predictions, but unless you are on a paid account the images will always be a day or two old. But one can use them sure and knowledge of what has happened weather and wind wise in the interim and then one can accurately predict what has happened sea temp wise and with an accurate weather prediction one can accurately predict sea temps in the immediate future too.

Sometimes though you find a warm pocket in cold water that is not predicted and its full of fish and if one just went fishing based on the charts one would never know..but most times when its cold..go to work or do the laundry, or make traces rather! Or go for deepwater bottoms that come shallower LOL..

The satellite resolution is quite good, not sure exact but you can zoom in well..but you will always be behind the changes..Things can happen quickly but it all depends on the thermocline down there and where it is..it can be shallow and water that is 8 degrees or more colder can be a few meters down, then the temp change will happen quickly, if it is 30 meters down then it could take a few days for the water temps to swing wildly, also sometimes a windchange can move cold water around on the surface quickly as the air pressure that was holding a mass of heavy cold water up against gravity subsides and then a high pressure of air ridges in and its literally gets pushed back down and the less dense warmer water rushes back in to replace it through hydraulics and fluid dynamics and it can happen quickly then as all was being held up as it was, cold, against equilibrium by external forces, when those forces dissipate or swing the opposite way, things change rapidly.

Thanks Dr.
I don't disagree.

A trap for all beach anglers, me included, is feeling the temperature with your feet when walking in to cast.

Your first cast temperature reading is "cold". The third cast the temperature has risen substantialy, only because in between the casts, your feet started to freeze, and returning to the cold water, you think the temerature has risen. NOT TRUE. It puzzeled me so muct that I started to take readings with my thermometer, to confirm water temperature hasn't changed.

The upside is, youbeleive temeratures changed for the better and you keep on fishing, and often with success....
