20 Mile is a coastal lake spot in south-central Alaska, situated along a narrow strip of land with shallow water characterized by visible tidal mudflats and marsh vegetation. The location shows a north-facing shoreline with a wide, flat water body to the north. This is a protected inland water environment rather than open ocean exposure.
The spot is defined by extremely marginal wind conditions, with only 0.4% wind reliability and average winds of 4.1 knots—well below the minimum required for kitesurfing (typically 10-12 knots). Water conditions appear calm with gentle tidal patterns visible in the mudflat structure. The narrow fetch and surrounded geography provide minimal wind acceleration.
Best wind direction would be easterly (90°) for side-shore conditions relative to the north-facing shore. This spot suits only those seeking very light-wind practice in stable, protected conditions. The extremely low wind reliability makes this impractical for regular kitesurfing sessions. Key considerations include cold water temperatures, shallow tidal zones requiring careful launch/landing planning, and the reality that wind conditions are insufficient for meaningful kitesurfing activity most of the time.
