Caution
- the tide information system is quite accurate. However, the predic-
tions are subject to variables, which, like the weather, are beyond the control
of man. The tide predictions are based on normal weather conditions. Hur-
ricanes and strong winds will often have a strong influence on the water level,
which can vary several meters. Changes in a coast line, either due to natural
erosion, major storms or larger man-made constructions, like breakwaters or
dredged canals, can also have influence on the local tide situation.
