Conditions at Virac Harbour in July

July: Monsoon Slump Continues

July offers little hope for consistent waves. Average swell remains at 0.5m (1.5-2ft), period at 7.0s, and ideal wind is only 5%. East swell still leads at 42.4%, with ENE at 14.1%, but the energy is mostly less than 1m and almost all of it is trade-wind chop. The rare S and SSE components are tiny, and there is no real groundswell to speak of.

The wind is the main problem. SW blows 19.6%, SSW 12.7%, WSW 9.9%, and S 6.2%, much of it at 20-40kph, creating directly onshore, blown-out conditions at the harbour. Rain is heavy at 9.22 mm/day and water temperature is a warm 29.6C. Expect small, soft, disorganised surf and only the occasional clean morning before the onshore flow strengthens.
