Surf Prediction Web Application

This project aims to develop a surf prediction web application that utilizes historical and current data on weather, waves, and tides to provide reliable surf predictions. This approach focuses on statistical methods rather than complex AI algorithms initially, allowing for a quicker development cycle.

---

Wave Prediction Model without AI

1. Data Sources

To build the wave prediction model, gather relevant data from various sources:

• Historical Wave Data: Obtain past wave heights, periods, and directions from sources like NOAA (National Oceanic and Atmospheric Administration) and various surf forecasting websites.

• Current Weather Data: Access real-time weather data, including wind speed, wind direction, atmospheric pressure, and temperature. APIs like OpenWeatherMap or WeatherAPI are useful for this purpose.

• Tide Data: Gather historical and current tidal information from tide prediction services or government oceanographic agencies.

2. Data Integration

Combine these data sets into a cohesive model:

• Data Storage: Store historical data in a database (e.g., PostgreSQL or MySQL). Use Python with Flask or Django to manage data collection and storage.

• APIs for Current Data: Set up scripts to fetch current data from the weather and tide APIs at regular intervals (e.g., hourly). Use libraries like requests in Python to pull this data and update your database.

3. Prediction Logic

Create a basic prediction algorithm using statistical methods:

• Statistical Analysis: Employ statistical techniques like regression analysis to identify relationships between historical weather conditions and wave patterns. For example:

  • Linear Regression: Predict wave height based on wind speed, direction, and tide level.
  • Moving Averages: Calculate moving averages to smooth fluctuations and help predict future conditions based on historical data.

• Rule-Based System: Implement a simple rule-based system with thresholds (e.g., “If wind speed exceeds 20 mph and is onshore, expect larger waves.”) for straightforward predictions.

4. Visualizations

Create visualizations to represent your predictions:

• Graphs and Charts: Use libraries like Matplotlib or Plotly to generate graphs showing predicted vs. actual wave heights, wind speeds, and tide levels over time.

• User Interface: Present this data on your web app, allowing users to see predictions, historical data, and correlations.

5. Iterative Improvement

As you gather more data and user feedback, consider gradually implementing more sophisticated methods, including:

• Machine Learning: Once you have sufficient data, transition to machine learning models to improve accuracy and account for more complex patterns.

• User Feedback Loop: Create a feedback system for users to rate predictions, helping to improve the algorithm based on real-world outcomes.

Advantages of This Approach

• Lower Complexity: Focusing on historical and current data allows for a solid foundation without the complexity of AI.
• Easier Debugging: Straightforward statistical methods make it easier to troubleshoot and refine predictions.
• Quick MVP: Develop a Minimum Viabl
