Frequently Asked Questions

GDTH (Good Day to Have Fun) is a web application that provides detailed historical weather data for any location on Earth. Instead of relying on unreliable long-range forecasts, you can use GDTH to see what the weather was actually like on your chosen dates in previous years, helping you plan outdoor events, trips, and activities with greater confidence.

A weather forecast is a prediction of future atmospheric conditions, which is only reliable about 7-10 days out. Historical data, on the other hand, shows you the actual, observed weather conditions (like temperature, rain, wind) for past dates. For long-term planning (months or years in advance), historical data provides a much more stable and realistic baseline of what to expect.

We utilize data from a variety of reputable meteorological sources, including government weather services and global climate datasets. Our system aggregates this information to provide comprehensive historical reports for specific coordinates, ensuring the data is as accurate and relevant as possible for your location.

The Basic tier offers free access to fundamental historical weather data, perfect for casual planning. The Pro tier unlocks advanced features such as detailed percentile data (to see the range of likely conditions beyond just averages), longer historical look-back periods, more detailed reports, and the ability to save and compare multiple locations, offering a more powerful tool for professional planners and serious enthusiasts.
