Top Features of WXTide32 and How It Compares to Other Tide ToolsWXTide32 is a long-standing, free tide prediction program originally developed for Windows. Despite its basic interface, it remains popular among mariners, fishermen, scientists, and hobbyists who need reliable tidal predictions without cost or heavy resource requirements. This article examines WXTide32’s core features, strengths, and limitations, then compares it to other tide tools available today so you can choose the best solution for your needs.
What WXTide32 Does Well
-
Accurate tide predictions from harmonic constituents. WXTide32 uses harmonic constituent files (station data) derived from official sources to compute tide and current tables. When correct station files are used, predictions are typically very reliable for general navigation and planning.
-
Small, lightweight, and offline. The program runs on modest Windows systems and does not require an internet connection for predictions once station files are installed. This makes it useful on boats or in remote locations.
-
Free and open distribution. WXTide32 is distributed freely, lowering the barrier for users who need tide tables but don’t want commercial software or subscriptions.
-
Custom station and location file support. Users can add or edit station files to improve predictions or create custom locations. This flexibility is valuable for local adjustments or private monitoring stations.
-
Simple export/printing options. The program can produce printed tide tables and simple exports for use in logs or planning documents.
Limitations to Be Aware Of
-
Aged interface and limited UX. The user interface is dated and less intuitive than modern apps; setup and station file management can feel clunky for newcomers.
-
No built-in charts or map integration. WXTide32 does not provide interactive maps, bathymetry, or visual chart overlays found in many contemporary marine apps.
-
No automated real-time observations. It predicts tides from harmonic constants rather than assimilating live tide-gauge data, so real-time deviations (e.g., storm surge) aren’t reflected.
-
Windows-centric. While it works well on Windows, use on macOS or Linux typically requires emulation or alternative ports.
-
Limited support and updates. Development activity and official support are minimal compared with commercial offerings.
Typical Use Cases
- Offline tide table generation for trip planning.
- Educational use — teaching harmonic tidal theory and prediction basics.
- Low-resource environments where small footprint applications are needed.
- Users who prefer manual control and the ability to edit station files.

How WXTide32 Produces Predictions
WXTide32 computes tides using harmonic analysis: each tide station is represented by a set of harmonic constituents (amplitude and phase for tidal frequencies). The program sums sinusoidal components for the target time to produce predicted water levels and current speeds/directions when constituent data include current harmonics. This method is standard and widely used in authoritative tidal predictions.
Mathematically: v(t) = Z0 + Σ A_i cos(ω_i t + φ_i) where Z0 is mean sea level, A_i and φ_i are amplitude and phase for constituent i, and ω_i is its angular frequency.
When to Choose WXTide32
Choose WXTide32 if you want a simple, free, offline tide table generator and are comfortable managing station files. It’s ideal for hobbyists, classrooms, and resource-constrained environments.
When to Choose Other Tools
- Choose commercial marine charting software if you need integrated navigation, real-time corrections, and professional support.
- Use online services or mobile apps when you need quick access to up-to-date station observations, mobile convenience, or interactive maps.
- Use XTide, pyTides, or other open-source alternatives if you need cross-platform scripting, automation, or integration into custom workflows.
Tips for Better Predictions with WXTide32
- Install the most accurate and recent station harmonic files available for your region.
- Compare WXTide32 predictions against a local tide gauge for a few weeks to gauge local offsets, then apply manual adjustments if necessary.
- Combine WXTide32 tables with weather forecasts: high winds and pressure changes can cause departures from harmonic predictions.
Final Thoughts
WXTide32 remains useful due to its simplicity, offline capability, and low cost. It’s not feature-rich compared with modern marine suites or web services, but for basic tidal predictions and educational use it’s efficient and dependable. Match your choice to your needs: pick WXTide32 for lightweight, offline tide tables; pick modern apps for maps, real-time data, and integrated navigation.
