"You did not save up for the past year to spend the week inside your hotel room. With a sunny vacation and a rainy vacation just days apart, we can put the odds on your side."
And once your site and date have been determined the forecast can help plan your packing and activities.
Over the past ten years, vacations planned with dryday have enjoyed significant odds on their side with accuracy up to 87%.
During that same time period, dryday forecasts outperformed planning on your own by a factor of almost three to one. This means that if you were planning with dryday forecasts during that period, roughly three out of four dryday forecasts would have provided you better odds over planning on your own.
The opposite is also true, if you were planning on your own, you would have been at a disadvantage around 75% of the time. Without a dryday forecast you could be planning dates or outdoor activities right in the middle of a period with a high chance of rain (Risky).
The dryday forecast system uses exact calculations of a number of forces that have been proven, by extensive testing, to be acting upon our weather at an exact date in the future, at an exact location on earth.
