More weather by SMS

Despite writing software for my own SMS weather service covering the East Atlantic, I still found myself checking sites such as windfinder and windguru whenever I was in port.

This was because I was sailing along the coast and the GRIB data used for my system produces data points for the high seas. Along the coast of Portugal and the Rias of Spain the data started at about 10 degrees longitude west. Good enough, but not perfect.

My solution was to make windguru coastal data available via sms.

Here is how to obtain it. Send a text message in the format:

wg:coruna

to the usual Belgian number +32498327494

This will return approximately two days worth of wind and wave data as two separate text messages for the city of La Coruna. Due to the limits of text messaging, precipitation and cloud cover are not included.

The list of data points that can be used is currently as follows (I’ll add more soon):

  • gibraltar
  • tarifa
  • meca
  • rota
  • mazagon
  • canela
  • faro
  • vilamoura
  • praia
  • sagres
  • sines
  • cascais
  • peniche
  • nazare
  • figueira
  • aveiro
  • espinho
  • viana
  • patos
  • rostro
  • laxe
  • coruna
  • cedeira
  • navia
  • salinas
  • gijon
  • moris
  • vicente
  • santander
  • orinon
  • laida
  • sebastian
  • hondarribia
  • mimizan
  • soulac
  • diamond
  • houat
  • glenan
  • trepasses
  • brittany
  • sablons
  • vierge
  • dossen
  • rose
  • malo
  • jersey
  • guernsey
  • becquet
  • salcombe
  • exmouth
  • lyme
  • weymouth
  • swanage
  • compton

Obviously you replace coruna (in the example given above) with the data point from this list that interests you. Note that only lower case letters are used.

The data returned looks like this (but with many lines):

Su20 11.6 15 2.3 13

  • The first two letters are the day of the week
  • The next two digits are the time for the forecast (in 24hr format)
  • Wind speed in knots to 1 decimal point
  • Wind direction compass rose. 0 is north 4 is East 8 is South and 12 West
  • Wave height in meters to 1 decimal point
  • Wave direction compass rose

So for Sunday at 20:00 hours the wind will be 11.6kts from the NNW. Wave height will be 2.3m and the swell will be from the WNW.

Hope it helps!

Sailing along the western coast of Portugal

Avian hitchhiker

24 Hours later I weighed anchor and started the 50 plus nautical mile leg north to Cascais on the outskirts of Lisbon. The sailing was in light winds on a relatively smooth sea, so generous use of my mighty 13.5hp Beta engine was necessary. Even at a consistent 5kts, it was almost dark as I approached the Rio Tejo. I really should learn to wake up earlier…

Dolphins made an occasional half-hearted visit, but this was more than compensated for by frequent social calls by exhausted avian hitchhikers.

Overall, the passage was soothingly tranquil, ignoring a brief episode of near panic when my favourite hat forced me into another impromptu “man overboard” drill. I did get it back however! As you can see in the accompanying photo, it is just the thing to compliment my sailing ninja apparel and I would be loath to lose it.

Sailing ninja apparel

I spent two nights in Cascais marina and I will happily return here (perhaps at anchor) in summer before heading toward Madeira or the Canary Islands. There are interesting little beaches, quaint winding cobblestone streets, and a multitude of bars, restaurants and cafes catering to all tastes.

I was also pleased to find the “out of hours” marina staff exceptionally helpful and professional; evidenced by the quick defusing of potential disaster as an accompanying Finnish yacht bungled repeated attempts to tie off at the reception pontoon. The incident prompted a spontaneous and amusing discussion on general marina mishaps, and having witnessed first hand what these people have to contend with on a daily basis, they have my deepest respect. Let me elaborate with an example;

Beach, Cascais Portugal

I’d noticed quite a substantial number of seagulls resting on the marina breakwater in the afternoon and a sudden cacophony of avian cries disrupted my hapless attempts at Wi-Fi prompting me to pop my head out of the companionway, I was just in time to see an enraged fisherman take out a pistol (the air gun type from the sound it made) and start shooting willy-nilly at gulls attempting their getaway with stolen fish. I’m afraid I do not have an accompanying photo captioned “enraged fisherman shoots sea birds”, but I was studiously minding my own business at this point.

Besides, dealing with this sort of thing is the business of those aforementioned, exceptionally helpful and professional marina staff. 😉

I was too tired to sample Saturday’s marina nightlife and had to content myself will meeting other cruisers “en passant” partaking in the new and ridiculously bizarre yachtsmen ritual of wandering marina grounds seeking improved signal strength for Internet Wi-Fi, laptops extended, face aglow.

Rounding Cape Saint Vincent to Western Portugal

How to tame boisterous children

Planning was high on my list of priorities as I methodically watched the weather forecasts pending departure. I did not care for a repeat performance of the previous days hair raising port entry. If I wanted to spend my free time surfing, I would have brought a Malibu board to Lagos rather than Eileen of Avoca.

As I waited for easterly winds, I busied myself with some serious relaxing at the beach occasionally burying a locals child to stop “it” running about and making a general mischief. Despite my best efforts, they continued to be a nuisance and even had the gall to find it all rather amusing. Oh well, I’ve never really been that good with kids.

Rounding Cape St. Vincent in calm weather

I’d decided the best way to tackle Cape Vincent was to leave at midday, round the cape during daylight hours and complete the total of slightly less than 80NM to Sines by night. The easterly winds dropped from force 4 to a gentle 1 and 2 overnight and while the sea maintained a significant swell, Cape Vincent came and went as an anticlimax.

Sprayed by dolphins

Dolphins escorted me for much of the journey, and their company was mostly appreciated, the exception being when a particularly cheeky individual would “sneak up” alongside Eileen and enthusiastically shock me awake with a spout of fishy smelling water. Who would have though dolphins had a sadistic sense of humour. I like them more and more each day! 😉

Aside from scaring the living daylights out of me by catching me unaware with their playful nocturnal antics, they effectively made sure I wasn’t going to catch any fish for supper.

I optimistically trolled with a brown lure (holding my newly acquired blue one in reserve), until at about midnight it was lost. to either:

a) the biggest fish I’d ever hooked (the dolphins at this point had vanished), or more likely;

b), a fisherman’ pot (even though I was at the 100m depth contour).

I’m newly resolved to fishing at night only when more than 10 miles off the coast.

At dawn I motored into the lovely little anchorage off the beach in Sines and set to work composing an opus in snore major.
