Weather Data For Garmin Inreach and Others
If you are using sailmail or winlink email systems, I do not recommend you use this service. See our other weather page for services that are more compatible with larger text and gribs.
Garmin and other companies have a few text based email devices that are good for retrieving short messages. This service is primarily for InReach users, but it will work from any email device with no access to grib or normal long text messages like email.
This is a FREE service. As such it might break at any time and Garmin might shut down my access since they do not respond to my requests for developer access. It is unknown how long I can keep this service working for Garmin devices. Use at your own risk!
What is this?!
This is a tool for you to send extremely short requests and get extremely short messages of 160 characters each back. It caters to the Garmin Inreach device, but there might be others out there that find it useful.
Here is an example of an InReach device getting a weather response from wx@svsarana.com
Some inreach devices allow for direct tethering so you can use your phone interface to send email messages. In this case the follow image illustrates what that would look like
Basic Features
Send an email to wx@svsarana.com using ONE of the basic commands in the message body:
catalog spot gfs rtofs ww3 roms gfdl lat,lon
Message bodies must contain at least one valid command. If your GPS position is on land you might get all 0's back for an ocean model. In this case you'll need to specify your Lat/Lon for a position on the ocean.
With the inreach system your GPS position is reported and can be used to generate a forecast (however only gfs model will
provide data if you are on or close to land). If sending from InReach, you can send a blank message to get the 24 hour
forecast using the SPOT model.
Sending lat,lon will provide a 24 hour SPOT forecast for that location. For example 25.3N,155W or you can use any deliminator
like [space][comma][colon][pipe] – see “command options” below for more information and as a quick example, the lat,lon option could be expressed as:
12.3N 155W 12.3N,155W 12.3N:155W 12.3N|155W
Command Options
Some keyboards like on the InReach, using a space or comma might be most convenient for separating options. For rtofs, gfs and spot commands you can follow them with the Lat,Lon and some other options and you can use any of the following characters to separate the options so all the following examples with latitude and longitude values are valid:
General Form: spot:lat,lon|hours|heading,speed|utc=offset|stats Deliminators: [space][comma][colon][pipe] ==> [ ][,][:][|] spot 10N 155W spot:10N:155W spot:10N 155W,utc=-7 spot|10N|155W|utc=-7|stats spot,10N,155W,utc=-7,stats
HOURS option
In general if hours is not specified it assumes a 24 hour time period and does it’s best to just send a single message back. Sometimes it doesn't all fit in one response, but in general the default 24 hours will try to produce the most compact result. You can set hours to 24 up to 96 in 6 hour increments. Remember that the longer the forecast the more messages required to send the information
HEADING,SPEED option
This ONLY works for the SPOT model, right now. You can request a forecast along a path using the heading as true degrees and the speed in knots. The forecast will then use your time interval specified by HOURS (or if not specified, 24 hours is assumed) and will compute a series f latitude and longitude points and provide a forecast along that line. So if you plan on sailing at 150 degrees at about 5 knots, you would follow this example. Here spaces were used as delimators but you can use [space][colon][comma][pipe] as separators:
spot 12n 150w 150 5 utc=-10NOTE: this option has to be used in pairs and do not mix up the order of HEADING,SPEED
UTC Option
To convert the dates and times to your local zone, use the UTC option to tell the forecasting software what your time zone is. For example Mexico is -7 or -8 depending on daylight savings and your time zone. Hawaii is -10
STATS option
The "stats" provides a statistical average from the forecast, which is good for just getting a long term overview in 24/48/72 hours.
spot,10N,155W,utc=-7,stats -- produces the following response for wind predictions:
24hrs: max/avg/min 12-17/11.2-15.4/10-14 @ 17.8 48hrs: max/avg/min 12-17/10.2-13.9/8-11 @ 11.4 72hrs: max/avg/min 12-17/9.2-12.6/6-9 @ 7.5
The ranges represent the values found during any given prediction interval. So for max wind 12-17 this means there were some
forecast values that only had max winds to 12 knots, whereas there were some other forecast results that had 17. For example if a
forecast had the following characteristics:
hour 1 - 10-12
hour 2 - 14-17
hour 3 - 15-16
The STATS shows max ranges from 12 - 17 for this time interval. The @ direction in degrees represents the geometrical average
of the wind direction over that time frame.
INREACH SPECIFIC OPTIONS
The Inreach device sends your GPS position of the unit to our severs automatically. If you want to get forecasts for your current location you can exclude the lat,lon options and just send one of the commands like these: [blank message will default to spot model and use current inreach reported lat, lon]

spot
gfs
gfdl
rtofs
ww3
roms
Background of Models
catalog -- produces a list of possible text regions from NOAA's meteorologists. This now works for many coastal areas in the US and Mexico/Central America region
and can be 6-7 messages long. This command returns a list of single word commands you can use to get the specific region’s catalog code.
PMZ-Pacific Mexico, Central America and N. South America PZZ-Washington, Oregon, California, Alaska GMZ-Florida 1 AMZ-Florida 2 PKZ-Alaska HIZ-Hawaiian Islands PHZ-Hawaiian Costal Waters
Sending the 3 letter code will produce the catalog codes for the specific forecast you want (see the end of this page for a full list). Since these lists are long,
it is best to know the codes ahead of time, rather than request the catalog which will take many messages to send. Ultimately you want
a code with 3 letters and 3 numbers like 'PHZ100' which would give you the Synopsis Hawaiian coastal waters within 40 NM
So for example sending the code '
spot is a virtual buoy model based on a composite of things. It contains wind (gfs) and sea state (ww3).
gfs works on ocean or land and provides temperature, wind, experimental precipitation estimates (see GFS)
gfdl is a climate model with cloud coverage and wind. It’s low resolution and only once a day.
rtofs is also ocean surface currents in text format but using a different model from oscar (see RTOFS)
ww3 is an ocean wave model with global coverage and is considered the standard for wave data. (see WW3)
The ww3 response appears like the following:

roms is a Hawaii Ocean Current model with coverage only for state of Hawai’i (see: ROMS)
New models are added from time to time as requested or as I want to use them.
