Each location is refreshed once every three hours. The hourly view, 7-day forecast, luck factor and packing notes come from the same stored update.
We compare the 7-day forecast with the version-matched historical observations available for the same time of year at Dee Why. The delta shows whether conditions look better, worse or about the same as a typical late July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Next to nothing in the water. Check back tomorrow. Short-period wind swell: expect weak, crumbly faces. Heavy offshore making for difficult paddle-outs but textbook faces. Not enough swell to get this spot firing properly.

Dee Why is a highly technical right-hand point break situated on the Northern Beaches of Sydney, Australia. The definitive bathymetric feature is a prominent, shallow sandstone rock ledge projecting from the southern headland. This abrupt obstacle intercepts powerful south-easterly groundswells, forcing the wave energy to heave violently over the incredibly shallow shelf. The result is a heavy, exceptionally hollow, square-shaped barrel right at the take-off. A westerly offshore wind is essential to groom the face and maintain the barrel's aperture. Due to the extreme speed of the drop, the severity of the rock ledge mere centimetres below the surface, and the highly concentrated take-off zone, 'The Point' is exclusively for advanced to professional surfers. It demands flawless technical tube-riding ability, as any mistake results in immediate impact with the unforgiving sandstone bottom, cementing its reputation as one of the most perilous waves on the coast.
Heads up: cold-shock risk, and rocks exposed at low tide.

The air here is 37% cleaner than the average comparison city right now.
Somewhat cleaner than a typical city. Air quality is unlikely to affect most people.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NOโ 5, Oโ 3, PM10 2, SOโ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 15:12

Dee Why is a point break and beach break on Sydney's Northern Beaches. The point break (Dee Why Point) is a heavy right-hander breaking over a rock shelf at the south end of the beach. The main beach offers multiple peaks. It is one of Sydney's better waves when the point is working, producing fast, powerful rights with barrel sections.
Dee Why Point needs a solid north-east to east swell. A south-westerly wind is offshore for the point. Best at mid to high tide. The 4-6ft range is ideal for the point. The beach break works on any east or south-east swell. Year-round but best February through August.
The Point: take-off over the defined reef at the south end. The right runs along the rock shelf towards the beach. The beach: multiple peaks across the sand. Choose based on conditions.
The Point has shallow rock throughout. The wave is powerful and fast. Getting caught inside over the reef is serious. Blue bottles in summer. The beach break is safer with sandy bottom.
Street parking and a car park behind the beach. Direct access. Full suburban facilities. Part of Sydney's Northern Beaches with excellent infrastructure.
Busy. Sydney's Northern Beaches are heavily surfed. The Point attracts a hardcore local crew on good days. 20-30 people at the point on solid swells. The beach spreads people out more.
Dee Why Point is a serious wave that demands respect. The local crew have surfed it for years and expect priority. Start on the beach break and observe the point before paddling there. The rock pool at the south end is excellent. The Northern Beaches have dozens of options within 10 minutes in either direction.

Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
