The Fish Index is based on Solar and Lunar Data for Larkspur Landing, CA. By calculating solar and lunar data, we devise a number to indicate the best times to fish in Larkspur Landing, CA. The higher the number the more likely fish will bite. The Fishing Index is based on the Solunar Theory devised by John Alden Knight.
Time displayed is based on Larkspur Landing, CA local time. The wind graph displays observations as reported in knots. The blue line and shaded area represents the average wind speed, the red represents gust value, and the green represents lull. Dots along the lines indicate time of data reported. The yellow arrows represent observed wind direction. An arrow pointing down indicates wind blowing from north to south, and is commonly referred as a "north wind". Note: frequency (and latency) of data is a function of the individual reporting station. Many non-WeatherFlow stations report data only once per hour. Check sensor notes for information on data source. Please read and understand disclaimer before using this information.
This is a derived product to show what the conditions will "feel like". The equation includes such parameters as temperature, wind speed, and humidity.
This product will vary depending on season:
If a location in the area gets below 50 degrees F, this product becomes a Wind Chill.
If a location in the area gets above 70 degrees F, this product becomes a Heat Index.
Otherwise... this product will simply reflect predicted temperature.
