The tide prediction curve above shows how fast the tide is rising or falling; you can see how long a height is sustained or see the heights at other times.

• Click on the Tomorrow or Yesterday buttons to move forward & backward in days.
• Click on Metres/Feet button to change between meters & feet.
• For times & heights of high & low tides, position your mouse cursor at peaks or troughs on the curve; read off the time & height in the lower left corner.
• For tide height at a particular time, position your mouse at the specific time & click its button. A horizontal red line appears at the corresponding height; the time & height appear in the lower left corner.

WARNING: A tide prediction is NOT the same as the actual tide that occurs. The predicted tidal heights should be considered those expected under average weather conditions. When weather conditions differ from what is considered average, corresponding differences between predicted levels & those actually observed will be noted. Generally, prolonged onshore winds or a low barometric pressure can produce higher levels than predicted, while the opposite can result in lower levels than predicted. During times of storm surges or when extreme weather conditions are imminent, it would be prudent to keep closely advised by local weather forecasts as they relate to the effects upon the tide levels.
