Hello Friends,
Rather cool – by Sydney standards – this morning, but the wind is offshore and we still have a microscopic line trickling in. The primary swell direction is out of ESE and it’s a about a metre on average out at the MHL buoy, but the average period is close to 7 seconds. So it is struggling to get much above the knee high mark. Take the mal or the SUP and have some fun chasing the little offshore walls, I’d say.
The forecast calls for a slight increase as the day goes along and although the wind is going to pick up, it’s set to stay more or less offshore all along our beaches. What would be good is if the period improved as well. And on that front I see that the average period down south has been gradually inching upward. It’s nothing spectacular, but both Eden and Batemans Bay are close to the 9 second mark.
Wondering what it might be like if we get up to those sorts of numbers here? Well, through the magic of tags, here is a link to some reports for days that the swell was out of the ESE at 1.5m at 8 seconds. For the last few years I’ve been recording the MHL Sydney buoy swell direction, height and period values and adding them as a ‘tag’ each time I do a report. My idea is eventually to be able to look at the forecast for these values and then pull up all the reports from our archives that match. So, by following the linked text above, you can see what I observed in the past when we had such conditions. Pretty geeky I admit!
Speaking of forecasts and such, it looks from this morning’s run of the models that we might possibly get a long period pulse beginning to fill in later today, so instead of 8 seconds or so, we could, if they’re right, get something above 13 seconds. A look at the tags collection shows that we haven’t had such a long period from the ESE, so I’m thinking it’s more likely to be out of the south and that those long period values will only be in the peak component. Even so, 13+ sec is juice, so it might be an idea to check the beach this afternoon and tomorrow morning.
I’m in magazine mode, so I can’t guarantee it, but I’ll try to file again later this afternoon.
Have yourself a fantastic day!

Weather Situation
A low pressure system is deepening near the Bass Strait as an upper cold pool moves over the southeastern Australia. The low and cold pool are expected to move slowly to the southeast during Tuesday and Wednesday and a high pressure system is expected to move west of Tasmania on Thursday extending a ridge to the northeast of the state.Forecast for Tuesday until midnight
Winds: Westerly 10 to 15 knots tending west to northwesterly 15 to 20 knots during the morning. Seas: Below 1 metre increasing to 1 to 1.5 metres during the morning. Swell: Southerly about 1.5 metres.Forecast for Wednesday
Winds: Westerly 15 to 20 knots tending west to northwesterly 10 to 15 knots during the morning then increasing to 15 to 20 knots by early evening. Seas: Up to 1.5 metres. Swell: Southerly 1 metre tending easterly late in the evening.Forecast for Thursday
Winds: Westerly 15 to 20 knots tending southwesterly 10 to 15 knots during the afternoon then tending southerly up to 10 knots during the evening. Seas: Up to 1.5 metres. Swell: Southeasterly 1.5 metres.






Well, as expected, it was really very small this morning as the sun rose on 1 July 2010 in Sydney. The MHL buoy is showing just half a metre of 8 second period south swell. From the look of the other swell buoy data along the coast, the flatness prevails from Eden to the Tweed.
