Like the sun, the moon rises in the east and set in the west. However, moonrise and moonset move from north to south and back again in the space of a month. The northern and southern extremes also change over a period of about 18 and a half years. The lunar standstill is when the northernmost and southernmost moonrise and moonset are farthest apart.

[...]

“If you were to look at these limits over 19 years you’d notice them change like an accordion: they expand up to a maximum limit (the major lunar standstill) and then start contracting up to a minimum limit (the minor lunar standstill).”

This major lunar standstill is due to happen in January 2025, but from now until mid-2025, the moon may appear, to a casual observer, to be unusually low and high in the night sky during the lunar month.

It has to do with a lunar cycle that happens about every 18-19 years that positions the moon in a way that moonrise and moonset are farthest apart for the lunar month. It's called "Lunar Standstill".
