Wind on the coast and offshore
Cross-offshore wind. The coast faces southwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

The moon in Heybeliada
Moon phase and position
Today the moon is 226,576 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 2:24–4:24 am Major · the moon passes overhead · high activity
- 2:56–4:56 pm Major · the moon passes underfoot · high activity
- 11:01 am–12:01 pm Minor · moonset · medium activity
- 7:50–8:50 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. 33 ft of water just 700 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 700 ft and 66 ft at 1,200 ft from shore.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
