Compared to the 'official' 10m wind, 30% stronger and 30 degrees veered (+30) at 1000 feet is a good rule of thumb assuming unstable well mixed air.
But it could be completely rubbish on a day with high stability (or for any one of a host of other reasons).
And the wind may well be much less at 2 or 3 metres off the ground (the bit you are landing in).
