Except if you're visiting a gliding site. If it's gliding only, most circuits are likely to be on the downwind side (to make the base leg into wind which gives the pilot more time to adjust).
Where it's a mix of gliders and power, it will probably be gliders one side and power on the other.
But this is generally irrelevant, as the only "standard" circuits at a gliding site are those by just pre- and post-solo pilots. You might find real or practice competition finishes (Vne approach at 100 ft or less, climbing into the circuit), joining the circuit at base, gliders flying circuits simultaneously on opposite sides, or (if one pilot I know is flying) an approach in ground effect.
No engine means we're all improvising and (I hope) looking out like crazy.
Bizzarely, this works remarkably well, and I've seen a dozen gliders landing at my own club within 5 minutes, no problems other than a long push back for some of them.
If you are landing at a gliding site a wide circuit is not recommended, as everyone else is flying a much tighter circuit and will not expect you to arrive from that position.
