Is all that is required, the presumption is always that without a condition/routing being added you fly direct to the point cleared. The surface wind is instant and therefore is passed when the pilot reports "Final". The surface wind may of course be requested at an any time but will still also be passed on the pilot reporting final.

If there is any doubt the controller may transmit: "route direct downwind right hand runway 34, QNH 1012". Whenever a non standard instruction is being passed it is encouraged for the controller to give an explanation "if time permits".
Talking for controllers outside the UK, and according to ICAO.

The correct phrase is "JOIN (position in circuit)....", nothing else, you could use "CLEARED DIRECT..." or "PROCEED DIRECT..." if you really want to stress it out though, or at least those are words out of normal phraseology. Don't assume anything, a "REPORT (position in circuit)..." is not a clearance per definition and does not relieve the pilot from entering and flying the circuit as properly should. Same goes the other way, I wouldn't assume a pilot enters and flies the circuit correct if I ask him to "REPORT BASE....", some do, some don't... and you learn by observing pilots.

Same with wind, ICAO dictates we give runway in use and wind prior to entering the circuit, it can be given via ATIS though. Most of us probably give it as part of the landing clearance as well, though the requirement is only for significant changes to a previous report.

And technically, the surface wind given by a TWR is not "instant", it's an mean wind direction and speed observation taken over 2 minutes with variations from this mean wind and speed within the last 10 minutes also reported, a gust has to last at least 3 seconds to be included. If the gust is more than 10 knots from the mean, you should be given a minimum and maximum speed instead of the mean speed. Same with variations... So no, you don't get an instant wind, unless you ask for it.

Generally we read the display, which should be set up according to the above.
