Tyre bulging/uneven

My front tyre (ContiRoadAttack3) with only 3,000 miles on it has an area with some sort of 'bulging' at the center of the tyre. I hope it's visible in the photo but with my fingers I can feel evident 'depressions' where the X's are in the pic.

Do you think it's safe to ride?

I'd be inclined to believe there's structural damage in the carcass of the tyre. It would probably be best to demount it and have it inspected prior to riding. A bit of cash is far better than broken bones (or worse).
Have you hit anything sharp and hard lately (like a kerb or pothole)? (Sorry, I don't know the Irish spelling or word for "pothole" but thought "tyre" and "kerb" would win me some points...

Statistically speaking, 50% of all people are below average.

Obviously, there is something seriously wrong with that tyre.

Do you think it's safe to ride you ask.

I may ride to the letterbox and back at walking speed.
Anywhere else. No. Not on your Nelly.

Already ordered a Michelin Pilot Street to replace it. Cannot find the same Conti at the moment, which btw costs twice as much.

This is obviously the direct consequence of the very small frontal whack I got the other day (my other post), but upon inspection I couldn't see any tyre damage at all after the incident, so I wasn't sure it was related and didn't mention it.

Don't want to ask a stupid question but is it possible the tire was mounted backwards? Can't tell from the picture.

No the tyre was mounted correctly last November. This is surely a consequence of the small hit I took, although after that I checked the wheel thoroughly (tyre surface, truing side to side and up and down etc) on my stand and it appeared to be OK (!?).

Today I HAD to take the bike to run an errand and noticed no wobbles or other issues, however I will definitely follow your advice and not ride until the new tyre comes. I hope Michelin front and Conti rear will be ok.
