Weather en route: a 5-day route forecast to the ship's email

Category: GeneralUpdated November 5, 2026

Weather en route is a daily email with a 5-day weather forecast along your vessel's route. Rynda works out where the vessel will be over the next 5 days and gives the wind and waves at those points. The email goes to the addresses you add, usually the ship's email. You turn it on for each fleet vessel separately, on the PRO and ENTERPRISE plans.

What the email contains

  • Subject: the vessel and the worst day, for example "NORD STAR: 5-day weather en route — 05 Nov DANGER, wind 34 kn, waves 4.5 m". If all 5 days are calm, the subject says "calm" with the highest wind and waves.
  • Header: the port of destination, the estimated time of arrival (ours and the one declared by the crew), when the forecast was computed and the speed used for the route.
  • A 5-row table, one row per day: date, the vessel's position at 12:00 UTC, wind in knots and Beaufort, waves in metres, and a mark.
  • Worst window: the day, hours and position where the weather is worst, if there is one.
Mark Meaning
OK calm
! caution
!! danger
ice icing possible

The mark comes from wind and waves, taking into account the vessel's navigation area from its classification.

The email is plain text with no images or attachments, about 1 KB. Lines are short, so the table reads well in ship email software. The only link in the email is unsubscribe.

When no email comes

  • The vessel is at berth or has no recent position: no email that day.
  • The vessel is at anchor or the destination is unknown: the email comes with a forecast at the vessel's position, without a route or ETA.
  • Weather data is not ready at the send time: the email goes out later, within two hours.

Where to see the forecast in the vessel card

In a fleet vessel's card, the Voyage tab has a Weather en route · 5 days block. It shows tiles: "Now" and one for each day, where the vessel will be at 12:00 UTC. Each tile shows the position, wind in Beaufort and knots, and the wave height. Days marked "caution" are highlighted in yellow, "dangerous" in red. If the vessel is at berth or has no recent position, a line with the reason replaces the tiles. Below the tiles, the Send the forecast to the ship's email line shows the email status, and its button opens the settings.

How to turn the email on for a vessel

  1. Open My Fleet and click the vessel name to open its card.
  2. Go to the Alerts tab. The Weather en route block is at the top. The button on the email line in the Voyage tab leads here too.
  3. Click Turn on. The line opens into the settings, with your address and 06:00 UTC already filled in.
  4. In Send time, pick an hour in UTC. The same time in your time zone is shown next to it.
  5. Type the ship's email and click Add or press Enter.
  6. Click Save. The settings close, and the line shows "Every day at 06:00 UTC → 2 addresses".

How to turn the email on through Captain Storm

Ask Captain Storm to turn the forecast on for a vessel, for example: "Send the weather en route for HERA to master@hera-ship.com at 04:00 UTC". The assistant turns nothing on by itself. Under its answer it places a Weather en route card:

What the card shows When What the button does
the time, the addresses and a Turn on button the email for the vessel is off turns the email on with this time and these addresses
the same with a Save button the email is already on, and you asked for another time or address changes the settings
an "already on" line and an Edit button the email is already on exactly so opens the settings in the vessel card
a See plans button your plan does not include the email opens the plans page

A new address on the card is marked "will get an invitation": the invitation goes out only after you press the button, and the forecast only after the address is confirmed. An address gets on the card only if you typed it in your question. After the email is on, the card has an Undo button that brings back the previous settings. The assistant also offers the email itself when the weather on a fleet vessel's route matters to your question.

Confirming an address

Your own profile email needs no confirmation: it is marked "Your address". Any other address receives an invitation email. The recipient opens the link and clicks Confirm on the page. The forecast starts only after that. Until then, the line below the email settings says which address the invitation went to.

Address mark Meaning
will get an invitation the address is added, the settings are not saved yet
Awaiting confirmation the invitation was sent, the recipient has not clicked Confirm yet
Confirmed the forecast goes to this address
Link expired 14 days passed without confirmation; click Edit, then Save, and the invitation is sent again

How many addresses and on which plan

  • Up to 3 addresses per vessel.
  • The email is set up for each fleet vessel separately: its own send time and addresses.
  • The email is part of the PRO and ENTERPRISE plans. On the free and Personal plans the block shows the "Now" tile and the first day, the other days are locked, and the email line has a See plans button.

How to unsubscribe or remove an address

  • Remove an address: click Edit, then the bin icon next to the address, then Save. Emails to that address stop at once.
  • Stop the email for all addresses: click Edit, then Stop emails. The addresses are kept, and the line shows a Resume button.
  • The recipient: the unsubscribe link at the bottom of the email, then the Unsubscribe button on the page. Many email apps also show their own unsubscribe button, which works too.

Where the forecast comes from

The forecast uses the GFS model for 5 days ahead. The route to the port of destination is drawn by sea around land and timed at the vessel's usual speed over the last 7 days. The forecast is for reference and does not replace navigational warnings and official forecasts.
