Add tide predictions to your own web site

Tidelets are Java applets that you can paste into your web site to give real time tide prediction graphs for any of over 4,500 locations world wide. Most parts of the world generally experience two high and two low tides per day though there are many exceptions to the rule. One example is Allington Lock, which is located on an inland waterway in the UK. The tidal curve show a complexity not revealed by conventional tide tables.

Notes
Use the tide graph's 'Tomorrow' and "Yesterday' buttons to advance or retard the curve a few days. See how the shape changes at different parts of the lunar cycle.

Menu options allow you to switch to other days in the past or future and to display tide heights in metres or feet. For times and heights of high and low water simply place the mouse cursor at peaks or troughs on the curve and read off the time and height from the table in the bottom left corner.

You want to know the height of tide at a particular time?
Place the mouse cursor at the time you need and click the left or right button. A horizontal red line appears at the corresponding height and the time and height appear in the bottom left corner tide table.

Advantages of tide curves
Tide curves show you how fast the tide is rising or falling. Traditional tide tables show only the times and heights of high and low water but give no indication or how long this height is sustained or of heights at other times. Simple rules for estimating the height at other times often fail where tide patterns are complex. Tidelets show the tide heights at all states of the tide - vital information if you're aground at low water for repairs, crossing a bar, stuck on a reef.

WARNING Tidelets have been tested under Internet Explorer versions 4, 5 & 6. Results with other browsers may differ. Please report any inconsistencies to Pangolin tech support
