Source of Data and Methodology
All calculations are based on data from NOAA Tide Predictions. All calculations strictly adhere to the formulas and data provided by this source.
The Formula Explained
To calculate tide predictions, the harmonic constituents are used: H(t) = Z0 + Σ (Hn * cos(ωn * t + gn))
Glossary of Variables
- Location: The geographic area for which the tide prediction is calculated.
- Date: The specific day for which tides are predicted.
- High Tide Time: The predicted time of the next high tide.
- Low Tide Time: The predicted time of the next low tide.
How It Works: A Step-by-Step Example
For a location like San Francisco on 2023-10-12, enter the location and date, then click "Calculate". The calculator uses harmonic constants to predict the high and low tides for that day.
Frequently Asked Questions (FAQ)
What is a tide?
A tide is the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of the Earth.
How accurate is this calculator?
The calculator uses data from NOAA, ensuring high accuracy in tide predictions.
Can I use this calculator for any location worldwide?
Yes, as long as the location has available tidal data from NOAA.
Why are tide times important?
Tide times are crucial for marine navigation, fishing, and coastal activities.
How often should I check tide predictions?
For critical operations, check daily. Otherwise, weekly updates are typically sufficient.
