Free wave prediction along a route
 |
Svašek Hydraulics provides free wave forecasts along a route for the next 7 days. This service is now (during this test phase) available for free.
|
Simply send an e-mail to waves@worldwavedata.com and ase as subject the word "route". In the body of the email information of the route should be given.
All positions are to be given in latitude, longitude in which positive latitudes refer to North and positive longitudes to East,
see the interactive map with co-ordinates or choose a map from the table below. Each blue dot in these maps represents a NOAA data point.

The number of waypoint may vary between 0 and 10. Delay (in hours) is anoption to shift the start of the trip.
Sailing speed should be given in knots.
An example of this format is presented below:
start position: 53.26,2.5 waypoint: 60,0 waypoint:60,-10 waypoint:55,-15 waypoint:45,-50 destination: 33,-30 speed: 22 delay: 2
Use plain text email format or rich text format (rtf).
HTML mail format is not supported.
Normally within a few seconds a reply mail is sent back with attached a text file which contains the forecast of the requested site for the coming 7 days. An example of the text file can also be seen below.
