The user can also download the presented weather data into a csv file by clicking on this icon:

Weather Issue Frequency

Weather issue frequency is dependent on project and weather provider. Typical weather issue frequency is every 6 hours for tabulated weather and every 6-12hours for 2D wave spectrum data. Daily issue time may vary, but usually quite consistent.

Weather issue information and other insight may be found in the "Weather Info" subpage:

Confidence Factor

Weather confidence factors are provided by some weather providers and gives an indication of forecast reliability. The confidence factor is presented as a colored bar (available in several places in the tool) and represented as high, medium and low.

Some weather providers do not provide confidence factors.

The following conventions apply to the weather data:

  • Waves (tabulated and spectrum) : clockwise from north, waves are "coming from"

  • Current: Clockwise from north, current is "going towards"

  • Wind, clockwise from north, wind is "coming from"
