The cyclical rise and fall of sea levels in the vicinity of the Virginia city are driven primarily by the gravitational forces exerted by the Moon and the Sun. These forces cause the water to bulge on both sides of the Earth, resulting in predictable periods of higher and lower water levels. These fluctuations influence various activities and environmental conditions in the area.
Knowledge of these sea level fluctuations is critical for navigation, coastal planning, and recreational activities. Understanding the timing and magnitude of these events allows for safe passage of vessels, informs decisions related to infrastructure development along the shoreline, and helps individuals plan activities like fishing and boating. Historically, communities have relied on this knowledge for economic stability and safety.
