dept of screeching halt

Posted by: on July 15th, 2010

Hello Friends,

Ah the wonders of the internet. Your correspondent may be far from the sea, but a quick check of the MHL data reveals that the microscopic conditions must be back again. In the space of around 12 hours, the average period dropped from around the 12 second mark to maybe six. The height of the swell at sea didn’t really change much at all, having never climbed much above a metre. So, when I looked at Rob and Matt’s reports this morning, I wasn’t too surprised. The Bureau’s hoisted a gale warning for strong SW winds today. They’re expected to last through tomorrow, but if the wave forecast models are right, there could be some south swell energy for tomorrow. Again, it looks like being a relatively short pulse ahead of another longish spell of small to flat conditions. Winter seems to be winding down a little early if you ask me. Our swell pulses are getting further apart and smaller…

Anyway, have yourself a top old day and go well with your plans!
