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.

🧭 Wind directions
Calshot Spit — a spit with water on the Solent AND Southampton Water sides, so you launch to suit the wind. A single facing bearing does not apply; the broad curated list is trusted wholesale.
Next 7 days at Calshot SpitBest of the week: Mon 26 Oct, ~20 kt around 12:00–15:00 BST (GOOD — the 9 m sweet spot) — very gusty (+14 kt), hard work, good kiters only. Lighter option: Tue 27 Oct ~19 kt — GOOD — the 9 m sweet spot. Models diverge on Monday: UKV 16 kt vs AROME 23 kt — lower confidence; lead model here is UKV 2km, check both before driving.
Windguru forecast
7-day forecast
Wind scale:<1010–1112–1314–1516–1920–2930+ kt ⚠
Public-model blend, for the full 7 days: The Met Office UKV 2km and Global 10km runs are read directly from the Met Office open-data feeds; AROME-FR 1.3km, IFS-HRES 9km, ICON and GFS come via Open-Meteo, plus MET Norway. Direction is a circular mean; gusts average only the models that publish an hourly-maximum gust. These numbers are raw model output with no coastal correction, so in the same weather they can read a little lighter than a coastally-corrected forecast — treat them as a floor rather than a ceiling. Temperature is from the Met Office runs (interpolated between 3-hourly steps on later days). No sea-state data is available. Tides from UKHO Admiralty (BST, 7-day window). The Windguru widget above is the unmodified Windguru forecast and is a useful cross-check.
Marginal — ~13 kt, big kites only. Peak ~13 kt W in the tide window. marginal — larger kites (14 m+) — most riders won't get planing; 15 m+/foil specialists only. ★ Gets dark at 17:53 — almost none of this window is in daylight.

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.
