Famous mile-long sand-and-shingle spit on the southern bank of Southampton Water. Works in essentially any wind direction because of the spit’s shape; NE/E give cross-to-cross-onshore at the front of the spit, and the summer SW sea breeze gets funnelled down the Solent reliably. Shallow sandbar on the Solent side at low tide creates a big butter-flat lagoon (ideal for learning). Watch for strong tidal flow around the spit.

Pick a past day to compare three things: the forecast we published (frozen before each hour, never revised afterwards), the wind that actually happened (Open-Meteo reanalysis, hours 05:00–21:00 UK), and what the live weather stations near the spot actually recorded (amber, from 2 Aug 2026). You can go right up to today — today shows the forecast and the live stations; the reanalysis for today lands tomorrow morning.
