(any wind direction)

The rose diagram shows how commonly and how strongly the wind blows from different directions over a normal April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3120 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Glenfield, located 36 km away (22 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Glenfield blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Glenfield. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each April) and blows offshore 27% of the time (8 days in an average April). Over an average April wind stronger than >40kph (25mph) was forecast for only a single days at Glenfield

We hope you find the new 12-day forecasts and additional details useful.

Kudos to everyone who helped us debug this over the past 3 months.

Be sure to click on the Advanced Surf option to see extra details about the sea-state. Look out for crossing swells and short period local wind swells and chop that will often spoil a groundswell even if the wind is perfect. As yet there is no allowance for this in the swell rating. This is something we are working on.
