Tombstones Wind Statistics, Summer averages since 2006
The rose diagram illustrates how commonly and how strongly the wind blows from different directions over a normal northern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 5802 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Tombstones, located 28 km away (17 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 prevailing wind at Tombstones blows from the ENE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Tombstones. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (9 days each northern hemisphere summer) and blows offshore 10% of the time (8 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Tombstones
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
