Nice image, Sanger. Pity it is an annoyance.
Notice that the streaking doesn't occur in the reflected lights
on the water.
I get streaks like this with my phone when there is a bright central-ish
source (recently, on a downlight in the ceiling). I can only put it down to
light bouncing off some internal parts of the camera when the aperture is
at a pretty wide setting. However I'm still about it.
A search on Google has lots of the same Qs asked and as many arm-waving
replies. I'd guess: try the same thing with your more controllable camera,
setting the aperture progressively from wide to narrow for each shot. You might
be instrumental in providing a definite reply.
CC, Image editing OK.

Good pick up...it was 2.5...and no filter.

Hmmm...There was a big bright light at the start of the jetty behind me.
Must go back and try to solve.

Maybe because I was down low looking up.
I shall practice
Hmm! Having had another - better - look at the exif, I see it was taken at f/9.
That almost suggests an answer to me:
It is caused by diffraction of the bright lights through the very small aperture that f/9
would give on a f=30mm lens - viz, about 3mm. Now, why they are aligned like that is
another thing. I bet, though, that the angle of the camera to the lights would have had
some effect, and if you shifted the image in the camera the orientation of the streaks
would change.

PS: the foregoing is NOT definitive.
You mentioned that this was at ISO 800, when you changed it back down, did this anomaly still occur?
Yep, same at f11, iso 100
Then I wonder how they'll go with the aperture more open?
Yep I wondered about sea mist which I noted in the first post.
It wasn't windy but I was close to the water with the wash coming close to me....it got me and the tripod a couple of times.
Dirty lens with a smudge mark being more sensitive to the brighter lights than the reflected ones in the water?
