What last night's forecast was worth
Yesterday the 46047 meter topped out at 15.6 kt at 9 am. The night before, NWS made no call, the other 4 models 13.4–15.2 kt.
How this was measured
One day is an illustration, not a record — a model that reads low every day will still land one. The number that means anything is the scored one over 90 days, in how our calls are graded.
Each model row is the highest wind it forecast for the 6am–6pm window at this meter, taken from the freshest run that existed before midnight the night before — between 6 and 23 hours ahead, depending on the hour. A model with no run in that window shows no call; it is never filled in from a closer-range forecast. Raw rows are the provider's own numbers; NWS + this meter's bias is that forecast shaded by this station's own measured error. That correction is Premium: a Premium rider is served the corrected row, and a free or signed-out rider is served the raw NWS row above it. The meter's figure is the strongest reading of each hour from this station's stored observations. Hours over your floor are counted from those readings alone; rideable is the nightly scorer's verdict and also weighs gust, direction and waves, so the two numbers are not the same measurement and are never added. Knots throughout.

Which way the working wind blows here
93% of the hours over 12 kt came from WNW–NNW in the last 48 days, the same quarter the wind most often sits in.
How this was measured
Floor is the 12 kt default; set a wind floor on an alert here and the rose is cut at yours. Hours the meter read at or over the floor: 622 of 1,096 (57%). Over the floor at the meter is not a rideable hour: gust, your direction window and the meter's own siting are not in it.
One reading per hour, the hour's strongest sample, from this meter's own readings over the last 48 days. Sixteen sectors. The two roses are each drawn to their own total: a light wedge is that sector's share of ALL hours, a dark wedge its share of the hours at or over the floor, and the rings are marked in the dark set's percentages. They are two distributions, not one inside the other. Direction is where the wind blows FROM.
