Estimate tide height, tide stage, time until high or low tide, boating clearance, fishing window, and beach access timing from local high and low tide times. This calculator is useful for fishing, kayaking, boating, beach walking, clamming, coastal hiking, and tide pool planning.
Local tide times:
Enter the local low tide and high tide times from a tide table. The calculator estimates where the current time falls within that tide cycle.
Tide height:
The calculator estimates tide height using a smooth curve between the low tide height and high tide height.
Activity planning:
The result includes tide stage, boating clearance, beach access status, and a general activity window suggestion.
A tide calculator helps estimate whether the tide is rising or falling, how much water may be available, and whether the timing fits fishing, boating, kayaking, tide pooling, clamming, or beach walking.
This calculator does not fetch live tide data. Use official tide stations and marine forecasts for navigation, safety, and exact local conditions.
This calculator uses a practical tide curve estimate:
Tide Height = low height + tide range × smooth progress through the tide cycle
You can estimate it by finding how far the current time is between low and high tide, then applying that progress to the tide range. This calculator uses a smooth curve instead of a straight line.
No. It is an estimate based on entered tide times and heights. Local geography, wind, pressure, river flow, and storms can change actual water levels.
Many anglers like moving water because bait and fish often move with current. The best tide depends on the species, location, structure, and season.
Use it only as a planning estimate. For navigation, use official tide tables, charts, depth sounder readings, local knowledge, and marine forecasts.
