Hello QRB fam, from UK Bread on 8. Took some time away. We are taking stock atm of our digs on the VICTORIA EMBANKMENT (TrafCam) aka EMB. Some of us feel they are not really trafcam pics but perhaps a tongue-in-cheek description by Q. This based on some anons actually going to Hungerford Bridge and taking a look. Also, you may notice the ROT3 and CH pics sequence descending the stairs of Hungerford Bridge until at street level yet being contemporaneous and of same image size/quality with the “traf cam” pics.
What follows is a copypasta of an analysis done on the UK Bread of the ROT1 image vs actual measured tide times and NightSky simulations on timeanddate.com for the relative Moon position times at which the Moon would be at a 151.5 degree bearing (as best as we could estimate) from Hungerford:
“A DISCUSSION OF THE RECORDED LONDON TOWER PIER TIDE TIMES FROM 17DEC2013 THROUGH 26DEC2013, THE DELTAS BETWEEN THOSE RECORDED TIDES AND ROT1 LUNAR MATCH TIMES, AND HOW THE OBSERVED DECREASE IN LUNAR ALTITUDES SEEMS TO CORRELATE WITH A DIMINISHED DELTA FROM ROT1 TO THE NEXT HIGH TIDE.
This is probly a gud time to say this anon is no expert on astronomy or lunar tide science. This anon is self taught on everything mentioned. I present open-source tide and moon measurements and observe. I do not tell anons what to think. Even my own working theories are challenged by the data. I know I said I was going to look at the weather, but as I had to go back and jot down the ROT1 times to do so I was impressed by the very high altitude of 54.58 degrees for the Moon on 17DEC. I thought that seems high to be seen behind London Eye when you consider that 60 degrees would be 2/3 the way up from horizon to directly overhead. So, I jotted down the lunar altitudes as well when taking the other info down.

(Remember the Rule of Twelfths for tides posted up bread. A tide that is an hour away from HT is 11/12 of the way in. Eleven twelfths equals .916. This tide is 90 percent in.)
As far as the tides and lunars go, in this look at the data, imho it seems to push in the direction close to Christmas for the EMB pics- and I am thinking about the HISP being at a high water position relative to her mooring dolphins (have not found open source pics showing her higher than seen in ROT1 picture.) Also, the deltas from the ROT1 to a measured high tide are closest at Christmas evening.
*= next day
**= estimated
LT unavail. = Did not have measurement and measurement preceding was outside expected time progression. Possibly due to high water runoff from tributaries making it longer til LT was achieved. On high tides, not see that occur with the last recorded HT, and so felt more able to project the 2 HTs following 23DEC.
Cheers, QRB.
