Portland Harbour
Large sheltered Olympic-venue harbour offering butter-flat water at most tides. SW/W gives silky side-offshore flat conditions; launch from the pebble/grass shore at Ferrybridge by Billy Winters. A Portland Port day permit (and insurance) is required to ride, and on easterlies kiting is low-tide only. Over 2.5 h from London — not a day-trip spot for most.
Next 7 days at Portland HarbourLighter option: Mon 15 Jun ~18 kt — an OK session on a 12 m. AROME and UKV 2km agree (within ~2 kt) over the next 60 h — confidence good (lead model here: UKV 2km).

Multi-model composite: the first 60 hours come from AROME-FR 1.3km and UKV 2km (AROME first, UKV filling its gaps); beyond 60 h the best available of HARM-DK 2km → ICON 2.2km → Zephr-HD 2.6km → IFS-HRES 9km → GFS 13km extends the table to the end of day 7. Temperature blended from GFS. Tides from UKHO Admiralty (BST, 7-day window). Always verify on Windguru.
Sub-kiteable — peak only 8 kt. Peak wind only 8 kt from SSE (11:00 BST). Below the kiteable threshold for almost every rider — big-kite specialists may still find ~30 minutes around the peak.
