Examples of navigator weather talk

Navigators realise you can’t predict the weather from a single snapshot – that is, by noting how the sky looks at one moment in time. Instead, you have to observe changes over time.

• 
  “The sky where the Sun is rising is clear – there are no smoky clouds caused by strong winds stirring salt into the atmosphere – so the winds will be relatively light today.”
  
• 
  “There’s a change from seeing squalls off the starboard side yesterday to a view of high towering cloud masses but no active squalls. The wind feels stronger than the day before, and I can see wavelets on the surface of the ocean. The wind is coming from the normal direction of SE trade winds. There are low-level cumulus clouds ahead. No indications of squalls – approaching an area of clean-flowing wind from SE, which will be steady. Predict that, in the next 12 hours, the wind will remain steady from the SE at a fairly constant speed, maybe 10 knots, so we will be able to sail north today.”
