Online data from Oceanographic buoy | | | | | Depth in meters can be obtained from pressure in dBars just with the transcription of the value, where the atmospheric pressure is already substracted. Example: 22.5 dBar of pressure means the depth of 22.5 m. |

From October 16th, 2002 to May 21st, 2003 the wind was sampled for 10 minutes in each 30 minute interval. The sampling frequency was 4Hz. From May 21st, 2003 on the wind is sampled continuously (30 minutes in 30 minute interval). The sampling frequency remains the same - i.e. 4Hz. | date and time end | gust speed (m/s) | gust dir (deg) | mean speed (m/s) | mean dir (deg) | 10.03.2010 07:15 | 44,5 | 118,7 | 21,6 | 92,2 | 08.08.2008 22:15 | 33,6 | 17,2 | 22,8 | 10,1 | 02.03.2011 08:00 | 32,4 | 98,0 | 21,9 | 100,8 | 07.02.2012 19:30 | 32,0 | 96,2 | 22,2 | 89,0 | 07.12.2003 03:30 | 25,6 | 57,7 | 18,8 | 62,1 | 24.01.2006 01:30 | 25,2 | 60,2 | 18,5 | 57,8 | 18.12.2006 19:30 | 25,1 | 81,0 | 17,5 | 79,1 | 24.12.2003 18:30 | 24,9 | 53,3 | 19,0 | 57,7 | 24.09.2004 12:00 | 24,8 | 70,5 | 18,7 | 71,9 | 11.04.2005 05:30 | 24,7 | 74,8 | 19,5 | 68,2 | | Top ten powerful Tramontanas that occur in summer | In Slovenia a word Tramontana is used for a strong northerly (hurricane) wind that blows from the Alps to the Venice bay over Trieste, Slovenian coast and Istra with gusts sometimes as high as 200km/h (usually 80 km/h). | date and time end | gust speed (m/s) | gust dir (deg) | mean speed (m/s) | mean dir (deg) | 18.06.2008 01:30 | 43,9 | 298,6 | 3,7 | 200,8 | 23.05.2007 14:00 | 42,7 | 0,4 | 3,6 | 215,8 | 09.08.2008 00:00 | 38,9 | 359,4 | 11,3 | 359,0 | 09.08.2008 00:30 | 33,6 | 17,2 | 20,6 | 16,9 | 18.06.2008 01:00 | 26,1 | 294,3 | 5,0 | 201,0 | 24.07.2003 18:30 | 26,0 | 253,4 | 7,3 | 236,9 | 16.06.2004 16:30 | 25,3 | 280,3 | 9,4 | 64,1 | 29.06.2005 20:30 | 25,3 | 307,1 | 7,2 | 295,1 | 28.07.2006 21:00 | 25,1 | 290,0 | 11,7 | 285,2 | 04.07.2007 15:30 | 24,9 | 352,8 | 8,9 | 344,4 | | Highest waves (higher than 2 m) from 2006 onwards |
