What are the particular challenges faced when landing at Bristol airport (UK)?
I have flown into Bristol quite a lot, as I live near there. Most landings are boring, but with good views on a clear day.  Most landings are also from the east, on 27 as the prevailing wind is from the west.

On the fairly rare occasions when you come in from the west on 09 it tends to be in unsettled weather, as that correlates with easterly winds.  You're also coming in over the Bristol Channel (not renowned for good weather, at least at sea level). Final approach from both directions is over some low but lumpy hills, more noticeable to the west of the airport.

"Earlier this year" written in April suggests late winter/early spring, when we had some interesting weather brought in from the NE. With the exact date it might be possible to narrow things down.

Overall it's nothing special but it's perfectly possible for a few things to come together to make it more interesting.
