Which description defines a spring tide?

• A. Small tidal range at quarter moons
• B. Large tidal range at new/full moon
• C. Water moving seaward, choppy
• D. All depths referenced consistently

Answer: (B)

Spring tides occur when the Sun and Moon line up with the Earth, so their gravitational forces combine to produce a larger-than-usual tidal range. This alignment happens during new moon and full moon phases, which is why the description of a large tidal range at the new or full moon best defines a spring tide. The other descriptions don’t fit: quarter-moon phases bring smaller tides because the Sun and Moon pull in different directions and partially cancel; choppy water describes sea state rather than how big the tides are; and referencing depths consistently is about charting or depth references, not tidal range. For planning a kayak trip, expect noticeably higher highs and lower lows during spring tides, which can affect landing spots and navigation.
