How accurate are HolyWeather’s Seoul weather predictions?

How often are Seoul forecasts updated?
Seoul forecasts are updated hourly. This helps prediction market users act on fresh information before markets resolve.
Does HolyWeather work with Polymarket?
Yes. HolyWeather is built for Polymarket users. It discovers Seoul temperature events on Polymarket, compares model-derived probabilities to market prices, and surfaces edges. Each market in the app links directly to its Polymarket event page for one-click trading.
What are 'edges' in HolyWeather?
An edge is when the forecast implies a different probability than the current market price. For example, if the model says there’s a 70% chance Seoul is above 5°C on a given day but the market prices that outcome at 50%, that’s a positive edge. HolyWeather highlights these so you can decide where to trade.
How do I get access to HolyWeather?
Access is paid. Visit the HolyWeather homepage, choose a plan, and complete checkout. After payment you get access to the Seoul dashboard, edges, and Polymarket links. If you have issues, contact support@holypoly.io.
Is HolyWeather only for Seoul?
Currently HolyWeather focuses on Seoul weather predictions because that’s where we see the strongest demand from prediction market users and active Polymarket markets. Support for other cities may be added later.
Where does HolyWeather get its weather data?
HolyWeather uses forecast data from Open-Meteo (which incorporates major models such as ECMWF and GFS) and applies its own processing and calibration. Market data and event links come from Polymarket.
