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.

We run 18Ghz links (licensed) for our bonded OC3 wireless hops. They
perform excellently in the urban environment. In the 2+ years we've had
them up, we've seen wind, rain, snow, fog, ice, rain, heavy rain... and
some more rain.
We lost signal once in heavy wind and have since changed our mounting on
the rooftop. (The other side is enclosed in a 72nd floor parapet.)
