Ten Meters is one of my favorite bands. Even when it's not "open", it's frequently open. With the sunspots on the rise, so should the activity on the band increase.
Have you found http://ten-ten.org/daily_nets.html yet? Nets listed there will help determine if the band is open. If you look at http://www.qsl.net/steelcity/nets/whichnet.html, one will see a search box that lets you know which nets are in operation.
http://www.dxwatch.com/dxsd1.php?f=92 or http://hamspots.net/10/ will also give you DX Cluster spots, just for 10 meters.
At http://www.vhfdx.info/spots/warnings.php, one can get email alerts when six meters is open. If SIX is open, it's almost a given that TEN is open.
http://www.dxmaps.com/spots/map.php?Lan=E&Frec=28&ML=M&Map=W2L&DXC=N&HF=N&GL=N also offers a map of openings AND the ability to post spots all in one place.
There's a number of 10 meter software defined radios that one can use to see where's the band is open. Two are dedicated to the "Beacon Band".
http://userpages.troycable.net/~wj5o/bcn.htm is a list of beacons on Ten. Tune here to see where the band is open, even when it's not.
