Mission Bay Wind

Confidence Score (0–100)

The score combines five weighted factors into a single number. A marine layer penalty can reduce it further.

Factor	Max Points	What It Measures
Wind Speed	30	Ideal range depends on sport — Laser: 8–12 kts, Wingfoil: 15–22 kts
Direction	20	W/WNW (240–310°) is the ideal thermal direction for Mission Bay
Thermal	20	Inland–coastal temperature difference that drives afternoon sea breeze
Gust Factor	15	Ratio of gusts to sustained wind — lower is more consistent
Time of Day	15	Peak thermal hours are 11am–3pm
Marine Layer	−15	Penalty when coastal fog/clouds suppress thermal development

Best Window

The 3-hour block between 9am–6pm with the highest average confidence score.

Thermal Gradient

As inland areas heat up relative to the coast, air rises and draws in cooler ocean air — creating the sea breeze that Mission Bay sailors rely on. A larger delta means a stronger thermal engine.
