    Fishing Charts Key Features

  • Daily Cloud-Free SST Image - Provides a complete, cloud-free sea surface temperature image in all regions. Updated daily.
  • Latest Satellite High-Res Satellite Imagery - Quickly select any shot you want from the last week in order to study the latest hi-res sea surface temperature, chlorophyll concentration and true color satellite shots in your region. These shots are updated several times a day.
  • Consolidated Chlorophyll/SST/True Color Menus - Unlike with the navigation systems used by our competitors, you can move between corresponding Chlorophyll/SST/True Color images without having to load a new page and re-zoom on your area of interest.

    You have the choice of viewing SST and Chlorophyll charts as a single image, 1-day composite image, or 3-day composite image. The latest single image is ideal for studying current offshore conditions, but during periods of heavy cloud cover users may also want to study a 1-day or 3-day composite image.
  • Overlay Ability - With one click you can overlay the latest Altimetry, Bathymetry, and Ocean Currents data over any fishing chart satellite image.
  • About Buoyweather Fishing Charts

    Buoyweather's Fishing Charts display a Cloudfree Sea Surface Temperature Image as well as the latest Sea Surface Temperature, Chlorophyll and True Color satellite images. Users can pinpoint and precisely locate relevant temperature and chlorophyll breaks offshore by moving the bullseye located in the center of the screen over areas of interest revealing precise lat/lon coordinates, water temperatures and chlorophyll concentration levels.

    Users may also overlay corresponding altimetry (sea surface height anomalies), bathymetry and ocean current imagery on top of any image by checking the appropriate boxes in the left navigation menu. Buoyweather's fishing charts also offer the unique capability of rendering opacity onto any image by checking the image opacity box, which will reveal the google map bathymetry through any SST or Chlorophyll Image. Concentrations of bait and gamefish will often occur where temperature and chlorophyll breaks are found in proximity to offshore structures such as ledges, banks, canyons and seamounts.

    How To Use Fishing Charts

    Using Cloudfree SST
    During periods of heavy cloud-cover, Buoyweather fishing charts cloudfree SST provides the best image available as it combines data from a variety of sources including infared satellite imagery that can see through cloud-cover as well as sea temperature monitors aboard ships and weather buoys.

    Using SST charts
    The latest Satellite images are posted on the fishing charts as soon as they are made available, making it possible to download and study the latest image prior to leaving the dock.

    These images can be very useful because they are updated several times a day and the exact time the image was taken is known. The disadvantage is that cloud cover will often obscure part of the image. This is why we give you a variety of shots taken over the last week so that you can pick a slightly older shot if necessary in order to give you a more complete image in a specific area of interest. It is also useful to check these images after a fishing trip in order to compare the imagery with the conditions you encountered while on the water.

    Use the latest SST shots to precisely locate temperature breaks within a region and know if the temperature break corresponds to the preferred water temperature of the species you are targeting (e.g. Striped Marlin are often found in water temperatures in the 66-77F range, Swordfish 61-70F range, Yellowfin 71-82F range Albacore 59-62F range)

    Using Chlorophyll Charts
    Chlorophyll charts show the density of phytoplankton in the water. Phytoplankton is a primary food source for most species of baitfish. The frontal boundaries between cold, nutrient and plankton rich waters and warmer, nutrient poor, clear blue waters are an excellent place to locate species such as billfish, tuna and other species of pelagics that will gather to feed on concentrations of baitfish and squid.

    Most large pelagic species are ambush predators that feed by sight, so you will often find them on the edges between clear blue water and cool, nutrient rich waters. Finding these frontal boundaries between bodies of warm and cool waters is key to finding concentrations of pelagic fish. These offshore frontal boundaries will also accumulate patches of seaweed such as Sargassum and Kelp that provide cover for bait and can provide excellent fishing in many regions.

    Using True Color Imagery
    True Color imagery is an actual satellite shot of your fishing region. The True Color Satellite image is processed to show true water colors and can be very useful to fishermen because in many cases you will be able to see edges of clear blue water next to green, turbid water along temperature and chlorophyll breaks. True color imagery makes it easy to locate color breaks in the areas where you plan on fishing.

    Using Altimetry data
    Altimetry or SSH (Sea Surface Height anomaly) data shows the height of the ocean's surface. Areas that with lower elevation (negative or low altimetry readings) represent areas of upwelling- where cold nutrient dense waters are pushing to the surface, conversely areas of high elevation represent areas of downwelling- where water pushes together and down trying to reach equilibrium. Generally speaking the best areas to fish are the neutral or slightly positive areas between upwellings and downwellings. Cold, nutrient rich water moving to the surface will cause phytoplankton blooms, causing small predators such as baitfish gather to feed on these microorganisms. In many cases larger predators such as marlin, tuna and other pelagics will gather to feed on these concentrations of bait, particularly if favorable conditions have been set up for several days.

    Using Ocean Currents
    The ocean currents data displayed by our system are calculated from altimetry readings that takes into account other variables such as the influence of the Coriolis effect. In the Northern Hemisphere currents spin clockwise around a downwelling and counter-clockwise around an upwelling. While not accurate on a very small scale, this ocean current model will give a general idea of large-scale current phenomena and eddy formations. This information takes 24 hours to process so the chart will always be a day old.

    Description of Fishing Charts Data Sources

    JPL Cloudfree SST Data - The fishing charts utilize SST data from the JPL (Jet Propulsion Laboratory) SST model at a global 1km resolution. The JPL model is unique in that it provides global cloud-free SST data from a wide variety of sources including numerous satellites in addition to monitoring devices on ships and weather buoys in order to provide a reliable image of waters temperatures even during periods of heavy cloud cover. This image processed and updated daily, so it shows the SST conditions that were present yesterday.

    MODIS - (Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra and Aqua satellites. Terra's orbit around the earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface including waters every 1 to 2 days, acquiring data in 36 spectral bands or groups of wavelengths. Fishing charts use MODIS data to provide the very latest Sea Surface Temperature, Chlorophyll and True Color data. The MODIS SST, Chlorophyll and True Color images are updated on the fishing charts as soon as they are released into the system, a date and time stamp is attached to each image letting you know precisely when the shot was taken.

    HYCOM - Fishing charts utilize HYCOM current and Altimetry data. The HYCOM (Hybrid Coordinant Ocean Model) consortium is a multi-institutional effort sponsored by GODAE (the US Global Ocean Data Assimilation Experiment). Hycom provides Fishing charts users with up to date current and altimetry data.
