What does solstitial mean?
Solstitial is an adjective meaning related to a solstice, the seasonal point at which the Sun reaches its greatest northern or southern apparent position and briefly seems to pause before reversing its direction. The word is especially used in astronomy and earth sciences. A “solstitial point” is the extreme position of the Sun's apparent movement, while a “solstitial tide” is a particularly large tidal range associated with the June or December solstice. The term is formal and uncommon in everyday speech, but it accurately distinguishes events connected with the turning of the Sun's apparent annual path from ordinary seasonal conditions.
adjectiveRelating to or occurring at a solstice, especially the point at which the Sun appears to stand still before beginning its apparent movement north or south. It is also used in the term “solstitial tide,” referring to a tidal range associated with the solstices.
- Relating to a solstice.
- Occurring at or near a solstice.
"The solstitial tides can produce some of the largest differences between high and low water along the eastern coast of North America."
"The solstitial point marks the northernmost and southernmost positions of the Sun in its apparent annual path."
"Researchers compared the solstitial tidal patterns with those recorded during ordinary tides."
“Solstitial” comes from the idea of the Sun apparently standing still before turning back toward the equator.

Where does solstitial come from?
The adjective comes through Latin from solstitium, a term formed from sol, “sun,” and stare, “to stand.” The underlying idea was that the Sun appeared to stand still at its northernmost or southernmost point before changing its apparent direction. The modern English word preserves this association with the turning points of the Sun's yearly path.
How solstitial is actually used
A formal, specialized term. It is most often encountered in astronomy, geophysics, and discussions of tidal ranges.
