When I was Chief Engineer at KCNS in San Francisco, we had a 23 GHz link
from our studio at 16th and Bryan up to Mt. Sutro. It worked fine until
the fog rolled in. IIRC, the path was only a couple of miles long at the
most. Not much different.

for microwave ovens is that they really like water, dive in, and lose
all their energy as heat! I put up a link that crosses Lake
Winnipesaukee in New Hampshire (about 1-1/2 mile) for a friend who
has a home plus a cabin on the other side. This was so that his home
Internet could be used at his cabin. It worked GREAT! --er unless it
was raining. Basically, if you couldn't see the opposite shore
because of rain, the WiFi link couldn't see it either. I experimented
with "Cantennas," disc-arrays, and pure Yagi antennas. Still, if you
couldn't see the opposite shore it wouldn't work.
