Caddebostan, Istanbul
18% of November days clear 12 kt for three daylight hours or more.
November sits outside the best months here. This report carries the record for November as it is, and no direction or session norm, because there is none to quote. Section 02 shows the year-by-year spread; section 06 shows which months to come instead.
Hour-by-hour & month-by-month wind
Rideable-day share by month, all three sports
Share of days with three or more daylight hours over each sport's threshold, counted from the record at 12 kt, Windsurf 13 kt and Wing 12 kt.
Blue fill scales with the share. Selected month outlined. Threshold per row: Kite 12 kt · Windsurf 13 kt · Wing 12 kt.
Where the wind sits, November
Share of daylight hours in each speed band, blue above the threshold.
Not drawn: 35% of daylight hours under 4 kt.
When in the day, November
Share of days over 12 kt at each daylight hour.
Rideable hours, not all hours. Every wind figure in this report is the mean over hours above the threshold.
November's own records
The month's own figures from three Novembers in the record, 2022 to 2026. Not the year's average.
What the percentage hides. A month at 80% can be twenty-four steady days or three windy weeks broken by a dead front.

No tide information found for this beach.
Tide data not yet available for this spot. The record holds wind, air and waves, not tide. Until a tide source is connected, the tables above stay empty rather than estimated. What the guide says about tide is on the next page, in words.

Istanbul Windsurf Center describes its bay as lying between breakwaters, like a closed pool for beginners, with water of standing depth at the entry and open water beyond for improving and advanced riders. It names rocks at the bay: beginners ride inside it, improvers outside the rocks. Ask the school where the rocks and breakwaters lie before sailing out. Gazete Kadıköy describes the Caddebostan beach behind the Irmak schools as sand, on the beach and on the seabed. The Sea of Marmara’s monthly mean water temperature is 20.1°C in June, 23.4°C in July and 24.2°C in August, and 8.2°C in February (Turkish State Meteorological Service, 1970 to 2024).
The swimming season runs from 15 June to 15 September, the same months as the wind: keep clear of swimmers. Under Turkey’s Ports Regulation (article 22(14)), swimming areas off beaches within port limits, up to 200 metres from the shore, are to be marked with floating markers from 1 April to 15 November each year, and ships and sea craft may not enter a marked swimming area. No other written rule for sailing off the beach was found in a harbour master’s or municipal source. The school makes life jackets compulsory on the water. In Turkey all emergency lines, including the coast guard’s former 158, are joined in 112. In an emergency call 112.
Getting there, packing & best months
November has no session mean to size from, so no sizes are given.
Best months, Kite. Record.
Sources, and their limits
Where each section of this report comes from. Record is measured. Modelled is computed by a formula because no measurement exists yet; it looks like data and is not. Written is WindChaser's editorial copy, compiled from the sources below.
The record
Hourly wind, 2022 to 2026, from DWD ICON-EU via Open-Meteo: a 7 km grid, read at the cell 3.0 km from the spot. It knows the wind over the cell, not the gust on the sand in front of you, and it knows the bearing, not the coastline: "side-onshore" is a rider's reading of the bearing. Each month is counted over three to four years.
What we could not source for Caddebostan, Istanbul
Which of the poyraz and the lodos blows more at Caddebostan. Whether the Caddebostan shore lies inside the Istanbul harbour master’s port limits (the Ports Regulation’s annex was not read), and any Kadıköy municipality rule for the beach. The Health Ministry’s bathing water result read first hand, and a first-hand reading of the local vibe. Crowds by month. A water temperature measured at the beach. A published price scale for the school’s lessons. A rider stay. Tide information. A station check on the wind record. A surveyed launch position. Where any of these is missing above, the section says so rather than filling itself.
Conditions change. Check local rules and conditions before you ride.
