Contest Official Rules

Weather Champs® currently offers (5) five different gaming modules: Sunrise Shootout, Sunset Showdown, The Weather Game, d3Wx and d5Wx. These games are considered games of skill and not games of chance because the following conditions are present in the gaming model; 1) Head-to-Head points-based system, 2) No randomized advantage being provided to any particular player and 3) Players have the ability to make the same selections for their weather predictions.

Weather Champs® does not offer real money gaming or real money prizes for rewards. Contest entry fees are paid for with Weather Champs® in-app virtual currency called Forecast Coins which have no real world value and are not exchangeable outside of the Weather Champs® platform. Forecast Coins are distributed to players who rank in winning positions on the leaderboard. Forecast Coin leaderboard distributions are listed under the more information section of each contest.

The game modules use the same scoring logic, game settlement logic and data provider as the arbiter of truth (Tempest) to settle each contest. Game settlement across all 5 game modules are based on the same or similar weather data points (Temperature, Humidity and Windspeed), but the time interval for the contest differs. You can read more about how to play each game type here. Below are the time intervals for each game type:

Sunrise Shootout - Today, you are predicting the Temperature, Humidity and Windspeed recorded tomorrow at Sunrise for the city you are playing.
Sunset Showdown - Today, you are predicting the Temperature, Humidity and Windspeed recorded tomorrow at Sunset for the city you are playing.
The Weather Game - Today, you are predicting the Highest Temperature, Lowest Temperature, Highest Humidity and Highest Windspeed recorded during the entire day tomorrow for the city you are playing.
d3Wx - Today, you are predicting the Highest Temperature, Lowest Temperature, Highest Humidity and Highest Windspeed recorded 3 days from today for the city you are playing.
d5Wx - Today, you are predicting the Highest Temperature, Lowest Temperature, Highest Humidity and Highest Windspeed recorded 5 days from today for the city you are playing.

The leaderboard displays contestants ranks based on how accurate their prediction was to the observed conditions for each city they play. Contestants scores are ranked in ascending order from the highest scores in position #1 (aka The Weather Champ) to infinity with the lowest score ranking at the bottom of the leaderboard.

4. Scoring System

Accuracy Percentage

The closer your predictions are to the actual observed weather data, the higher your Accuracy %.
Accuracy is calculated using this formula:

Accuracy % = 1 - ((ΔCondition1 + ΔCondition2 + ΔCondition3 + ΔCondition4) / 100)

Example Calculation:

Condition Prediction Actual Δ (Difference)
Highest Temp.: Forecast 90°F | Observed 92°F - 2Δ
Lowest Temp.: Forecast 82°F | Observed 80°F - 2Δ
Highest Humidity: Forecast 95% | Observed 98% - 3Δ
Highest Wind Speed: Forecast 7 mph | Observed 5 mph - 2Δ
Total Delta = 2 + 2 + 3 + 2 = 9
Accuracy % = 1 - (9/100) = 91%

Time Stamp Bonus

The earlier you submit your forecast, the higher your Time Stamp Bonus.
Time bonuses help break ties and boost final scores.

Final Score & Leaderboard Ranking

Final Score = Accuracy % + Time Stamp Bonus
Players are ranked highest to lowest based on their final scores.

5. Editing Predictions

Forecasts can be edited anytime before the Entry Window closes (11:59 PM local time).
Resubmitting a forecast updates the time stamp, affecting the Time Stamp Bonus.

6. Contest Malfunction Policy

If a system malfunction prevents contest completion, the contest will be canceled and entry fees (if applicable) will be refunded.
