Oh wait, we lied.

Hello All-

This is Melissa and Dani from the Waves group.  This week we found a couple of websites with archived weather data from Vigo, Spain (which is the closest city to our wonderful Capo Silliero wave-buoy).  This website, Weather Underground, has day-to-day records of temperature, humidity, pressure, weather and lunar cycles.  This will help us to determine the cause of the "scary" wave heights we've been seeing.  From what we have observed, the scary waves are due to long periods of overcast and rain/storms.

We also looked at a site recommended to us called Windfinder.  This gives us the wave and wind forecasts for the upcoming week.  This does not help us too much; although there is archived data, it comes at a price (literally).  We can at least use this site to forecast the wind patterns for the next week, and look at the Puertos del Estado site to compare the wind, weather and wave data.

From looking at the Puertos del Estado wave data, we are concluding that the waves aren't as scary as we previously thought.  Why, you may ask?  In the graph below of the wave heights from November 2006; the black is the average wave height and the gray is the maximum wave height for that day.  Here, the wave heights are, on average, between 2-4 meters:

picture-11 We can connect this data (from November 2006) to the archived weather data from wunderground.com to explain why the wave heights were so large or small.  For example, the biggest wave heights here are on November 27 and 28.  If we look at the archived weather data of those two days, we can see that both days had heavy rain showers.

From this, we can say that weather has EVERYTHING to do with waves.  If there is a storm, rain, overcast (what have you), there will be bigger waves.

That is all,

M and D
