It is very readable, and the weather elements you show can be changed to suit your needs.\u00a0 This graph shows something called significant wave height (SWH).\u00a0 It is an estimate of the average of the biggest 1\/3 of the waves that are expected.\u00a0 Combined seas tells you the biggest waves to expect, while (SWH) lets you know what you will be \u201chit with\u201d on a regular basis.\u00a0 In other words, how comfortable will the waves be.\u00a0 I use (SWH) in my go\/no go decision making.\u00a0 When the (SWH) is equal to or greater than the period, I don\u2019t go.\u00a0 For example, a (SWH) of six feet isn\u2019t bad, however, if those waves are coming at a six second period, it gets very uncomfortable and I don\u2019t recommend going.\u00a0 I checked this forecast a couple of days ago.\u00a0 The combined heights of the wind waves, primary swell, and secondary swell was 8 feet.\u00a0 The period was 9 seconds.\u00a0 Both within Tradewinds policy.\u00a0 The SWH was 5 feet at 9 seconds.\u00a0 Well within my personal go\/no go standard.\u00a0 I also noticed that the Temperature and Dew point lines touched in a few places, which indicates a small potential for fog.\u00a0 I have this link set for 8 miles outside the gate.\u00a0 You can change it by changing the Lat\/Lon in the web address.<\/li>\n<li><a href=\"http:\/\/forecast.weather.gov\/shmrn.php?mz=pzz545&amp;syn=pzz500\">http:\/\/forecast.weather.gov\/shmrn.php?mz=pzz545&amp;syn=pzz500<\/a><br \/>\nVery good, very easy to read five day forecast of weather and sea state in the area off the Golden Gate, out to 10 miles, shown in simple text.<\/li>\n<li><a href=\"http:\/\/www.opc.ncep.noaa.gov\/P_e_sfc_color.png\">http:\/\/www.opc.ncep.noaa.gov\/P_e_sfc_color.png<\/a><br \/>\nThis is a surface analysis for the eastern pacific.
