Find Fishing Hot Spots

Beyond planning your trips and staying ahead of the weather, NavNet TZtouchXL's FREE TZ Weather helps you determine the best areas to catch fish based on current, waves, and wind. Part of the update with software version 25, TZ Weather gives you a ton of free weather data that can be easily downloaded onto your TZTXL MFD. Premium weather is also available with a $8.99/month subscription. Take a moment to visit with Capt. Mike Genoun of Florida Sport Fishing TV as he walks you through how he uses TZ Weather to get on the bite.

Sea Surface Temperature (SST)

Understanding water temperature is critical for fishing and route planning. TZ Weather's SST overlay highlights subtle changes in surface temperature, helping anglers target specific species and enabling cruisers to locate currents or thermal boundaries that affect comfort and fuel efficiency.

Sea Surface Height (SSH)

SSH data reveals changes in ocean surface elevation, a key indicator of currents and eddies. With TZ Weather, you can visualize these subtle shifts, ideal for offshore anglers looking to pinpoint zones of upwelling where baitfish and predators gather.

Chlorophyll Concentration

Chlorophyll overlays help identify nutrient-rich areas of the ocean, often correlating with zones of high biological activity. Use this layer to locate productive fishing grounds, as chlorophyll concentrations can indicate where baitfish - and big game - are likely to be found.

Wind and Wind Gusts

Wind direction and speed are central to voyage planning. TZ Weather provides reliable wind forecasts with high-resolution detail, so you can avoid headwinds, take advantage of favorable conditions, and ensure a smooth, fuel-efficient journey.

Wind gust overlays help you prepare for sudden and temporary increases in wind speed, which can impact vessel handling and safety. TZ Weather offers gust data with excellent resolution and accuracy, giving you a clearer picture of short-term wind dynamics.

Wave Height & Direction

Stay ahead of sea conditions with TZ Weather’s wave forecasts, which show both wave height and direction. Whether you're planning a crossing or anchoring overnight, this layer helps you find the smoothest ride and safest anchorage.

Air Temperature

TZ Weather also provides accurate air temperature forecasts to help with comfort planning and environmental monitoring. Whether you're trying to beat the heat or prep for cooler conditions, this layer lets you anticipate changes in onboard conditions.

Air Pressure

Barometric pressure is a critical indicator of weather trends. With TZ Weather, you can visualize pressure systems moving through your area, making it easier to spot developing weather fronts and plan around potential storms.

Currents

TZ Weather’s current overlay displays ocean currents in real time, helping you optimize navigation routes, reduce fuel consumption, and better understand how water movement may impact your position or drift.

Cloud Cover

Cloud overlays help you monitor sky conditions and anticipate changes in visibility, sunlight, or the likelihood of precipitation. Whether you're navigating visually or planning for solar charging, this layer provides valuable context.
