Hello Friends,
A break in the rain early Saturday morning. As of 0620 the wind was out of the ESE at 13-17 kts and out at sea the MHL buoy was seeing 2.7 metres of 7-second energy from 140-152° (ESE). There were some sizable looking sets along the Collaroy to Narrabeen stretch which, combined with the 1.9 metre high tide at 0820 could mean noticeable erosion at key points along the beach. We’ve had more that 100mm of rain in across the catchment in the last 24 hours, and that comes on top of a similar amount Thursday. The upshot is that all city beaches are likely to have pollution from stormwater run off. In fact, there was a bypass event at Warriewood yesterday.
I saw a few people bobbing around in the swill at Dee Why point, but nowhere else. Waves were in the chest high range with the odd bigger one and it was messy looking thanks to the relentless ESE wind. I wouldn’t risk a case of something bacterial for it myself.
We have a strong wind warning for today and a gale warning tomorrow. Plus there will be heavy rain at times on both days. Tomorrow should see a peak in the swell energy, but there should be enough size to surf all week. The big issue will be water pollution and non-stop onshores. Some models are showing a brief interlude between the strong wind conditions around midweek.
Weather Situation
A strong high pressure system to the south of Tasmania extends a ridge into the Tasman Sea, while a deepening trough lies along the New South Wales coast. This pattern is expected to bring fresh and gusty onshore winds to most coastal areas during the next few days. Some areas may experience strong to gale force winds as the coastal trough deepens, potentially giving rise to small low pressure circulations.
