# How to Use Weather Forecasting Tools in Savvy Navvy

|| Some chart overlays are only included in our premium plans. Learn more about Savvy Plan Pricing here.

Savvy Navvy offers powerful, high-resolution weather forecasting tools to help you plan safe and efficient trips. You can view forecasts in two main ways: via the **Weather tab** or through the **Weather chart detail layer**. Both give you access to accurate wind, temperature, and precipitation data — so you can make confident decisions before and during your voyage.

### Two Ways to View Forecasted Weather
By combining these two tools, you’ll always have a clear understanding of both **local conditions** and the **wider weather trends** in your boating area.

* [Weather Tab](#6-1-weather-tab-explore-detailed-forecasts-for-any-location) – Best for detailed, location-specific planning.
* [Weather Chart Detail](#6-2-weather-chart-detail-see-real-time-wind-animations) – Best for getting a big-picture view of wind patterns and how they’re expected to change.

###### 1. Weather Tab – Explore Detailed Forecasts for Any Location

The **Weather tab** lets you view forecast conditions for any point on the chart.

**How it works:**

1. Tap the **Weather tab** at the bottom of your screen.
2. A weather marker will appear on the chart at your selected location.
3. To check conditions for another spot, **drag and zoom** the chart until the marker is over your desired location.

**What you’ll see:**

* **Wind speed & gusts** – Average wind speed and gust strength, shown alongside wind direction arrows.
* **Weathergram** – A visual timeline showing forecast wind, gusts, weather icons, temperature, and rainfall.
* **Forecast length** – Varies by plan. Free users get shorter-term forecasts, while premium plans unlock extended forecasts up to 14 days.
* **Day/night shading** – Nighttime hours are shaded darker for easy visibility.
* **Scrollable timeline** – Swipe forward to see how weather changes over time.

💡 **Tip:** This view is perfect for comparing weather conditions at potential anchorages, marinas, or open-water waypoints before you decide on your route.


###### 2. Weather Chart Detail – See Real-Time Wind Animations

If you want a quick, visual overview of current wind conditions across your chart area, use the **Weather chart detail**.

**How to enable it:**

1. Tap the **Layers icon** (diamond shape) on the right-hand side of the screen.
2. Toggle **Wind** under “Chart Details” to turn the animated wind overlay on or off.

**Features:**

* **Animated arrows** – Show wind direction and speed at a glance.
* **Colour coding** – Quickly identify conditions using our wind speed colour scale:
           •. Blue – Light winds
           •. Green – Ideal boating conditions
           •. Yellow/Orange – Uncomfortable conditions
           •. Red – Dangerous conditions
           •. Purple – Extreme conditions
* **Forecast scrolling** – Use the timeline to move forward in time and see how conditions will change.
* **Energy saving** – The animation can be demanding on your battery, so it’s best to turn it off when not in use.
