Cover it with black plastic. Duck weed needs sunlight to survive.

Try to establish some shade giving plants/shrubs/trees. That will alleviate
the problem

My pond is mostly in shade, but when the sun is high in the sky the
water gets sun on it. Maybe later this autumn the weed will die off
anyway?

Thanks, I will live in hope.

It dies off and sinks to the bottom, adding to the build-up of silt.

Then it regrows next year!

Don't get fooled, remember duck weed sinks down in winter and pops back
up again in spring, it is however quite difficult to grow and I have been
trying for years to establish it without success (helps keep the water
nice and clear) and my pond has high nitrate levels and full sun but it
is windy and I am wondering if Duck weed requires a very sheltered water
surface?

Some years it completely covers the IJsselmeer, although not so far this year.
Tourists have been known to take short cuts across canals in the semi dark
because they mistook the duckweed for lawns.

I nearly fell for that myself when I was a youngster. Recently I saw a
dog chase a cat across a duck weed covered pond. They both got a bit
wet.
