Low tide was 10pm so high tide was at 4am (4 May). Good point about how far up high tide comes in over the rocks. Google Earth link please. It took me 15 minutes to find those images Sadie.
Pathfinder, I dont know how to post GE images or I would put it up.
Please note:
I am sorry Pathfinder, my eyesight is failing and I read the GE date wrong, it's in very small font. It should be 7/16/2011. (highish tide)
Another image showing a lowish tide is dated 9/19/2004
Maybe Pegasus could help please, or John? They both know how to post GE images, I think.
Otherwise , go into GE
1) type * Praia da Luz, Algarve * in the fly box.
2) You will immediately find the coast line at the south of the image.
3) Pull the image to waht you want to look at
4) Zoom in or out according to what you want to see
5) Then look on the band at the top of the image, the one with boxes in it.
6) About 6 boxes from the left, you will see a clock, click on that
7) A slider will come down with dates on it, move the slder to the date you want and the image with change to show historical images
Magic !!!
Hope you can understand my instructions. Good luck with it.
Highish tide = 7/16/2011
Lowish tide = 9/19/2004
Have a look at all the dates to see how it changes in various tidal conditions.
Particularly interesting to me is how the little western beach vanishes at high tide and becomes just a rocky inlet with sea right up to the rocks. I reckon that was a smugglers cove at one time and the cave/ tunnel at the back stored the smuggled stuff, or it was transported thru the ?tunnel to premises behind .... only an educated guess tho.
