Could they be Lumpsucker eggs? They usually turn up a bit earlier in the year but they are large eggs in coherent, yellow/orange masses.
On the other hand, we should just about be at the start of the wrasse breeding season and the ballan wrasse lays eggs in a "nest" in the low intertidal and pools.

In commercial Lumpfish 'caviar' the eggs are smooth spheres without the surface ornament shown above. Of course, the lumpfish 'caviar' may be from a different species.
These are also much larger than the dyed black commercial stuff.
Whatever laid them where they were was 'off-course' or they can survive periods out of water, as they would be exposed at each tide over several (5-7) days at fortnightly intervals.
They were also not in a place that could have been guarded easily.
