Understanding Tide Tables and Their Importance
What Are Tide Tables?
Tide tables are detailed charts or schedules that display the predicted times and heights of high and low tides for specific locations over a given period. They are essential tools for planning activities that are affected by the ocean's changing levels, such as sailing, kayaking, fishing, and beachcombing.
Why Are Tide Tables Important in the Scilly Isles?
The Isles of Scilly are characterized by their shallow waters, numerous coves, and tidal islands. The difference between high and low tide can be significant, affecting accessibility, safety, and the timing of activities. For example:
- Boating and Sailing: Tides influence navigation, passage planning, and mooring.
- Fishing: Certain species are more active or accessible at specific tidal phases.
- Beachcombing and Walking: Some beaches are only accessible or safe at low tide.
- Diving and Snorkeling: Visibility and access points can vary with the tide.
Knowing the tide schedule helps you plan your activities effectively and safely.

How to Read Tide Tables for the Scilly Isles
Key Components of Tide Tables
Tide tables typically include:
- Date: The specific day for which the tide data applies.
- Times of High and Low Tides: Usually given in 24-hour format or standard AM/PM.
- Tide Heights: The predicted water level relative to a chart datum, often in meters or feet.
- Tide Phases: Indications of spring or neap tides, which affect the magnitude of tidal variation.
Understanding Tidal Cycles
- High Tide: The point when the water reaches its maximum height.
- Low Tide: When the water recedes to its lowest point.
- Tidal Range: The difference in height between high and low tide; larger ranges can influence the best times for specific activities.
Example of a Tide Table Entry
| Date | High Tide Time | High Tide Height | Low Tide Time | Low Tide Height |
|------------|----------------|------------------|--------------|----------------|
| 2024-05-01 | 03:45 AM | 4.2 meters | 10:15 AM | 0.5 meters |
| | 04:30 PM | 4.3 meters | 11:45 PM | 0.6 meters |
This example shows the predicted high and low tides for a specific date, helping users plan activities around these times.
