You are correct about the re-entry burn altitude. In fact, you can see grid fin deployment right after separation in the video. However, there is a second landing burn and I mistook the photo for that.

Regarding weather, here is the statement from the SpacEx website:

While extreme weather prevented SpaceX from attempting to recover the first stage, data shows the first stage successfully soft landed in the Atlantic Ocean within 10 meters of its target. The vehicle was nicely vertical and the data captured during this test suggests a high probability of being able to land the stage on the drone ship in better weather

Weather at the launch site was great (as evidenced by the clarity of the separation images). Weather at the landing location out at sea was not.

Note 3:50 time mark
