Hi Molly, great question!
Objects in the night sky technically reach their ‘peak’ when they cross the meridian (i.e. directly due south) at midnight. For the Pleiades this month, that’s around 20 November.
The Pleiades reaches its highest point in the southern sky consistently over the next few months, so the peak height doesn’t change, only the time that it reaches that peak. So tonight for example, Pleiades crosses the meridian around midnight, by Christmas it’ll be highest at 10pm, by the end of January it’ll be 8pm, and by February, it’ll still be daylight when Pleiades is highest.
