Tonel Swell Statistics, December: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Tonel that coincided with light winds or offshore conditions through a typical December and is based upon 2953 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow represent increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was WNW, whereas the the most common wind blows from the NE. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 41% of the time, equivalent to 12 days. Open water swells exceeding >3m (>10ft) only happen 1.7% of the time in a typical December, equivalent to just one day but 18% of the time we expect swell in the range 2-3m (6.5-10ft) 18%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Tonel is exposed to open water swells, we calculate that clean surf can be found at Tonel about 41% of the time and that surf is blown out by onshore wind 52% of the time. This is means that we expect 28 days with waves in a typical December, of which 12 days should be clean enough to surf.

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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
