Signal-Trade-Core / weather-prediction-bot

What is weather-prediction-bot?

This is a Node.js automation tool that scans Polymarket's temperature prediction markets and automatically trades on them based on weather forecasts. The bot pulls data from the National Weather Service for US cities and Open-Meteo for international locations, maps the forecast high to the matching temperature bucket on Polymarket, then either prints signals, runs paper trades against a local ledger, or posts real orders to the Polymarket CLOB on Polygon. You configure it through environment variables, pick your cities, set price thresholds, and it handles the rest.

Why is it gaining traction?

The hook is simple: it removes the manual work from a clearly defined strategy. Weather markets resolve on specific stations, forecasts are public, and the logic is deterministic -- this bot just executes that logic on a schedule. The three-mode approach (signal, paper, live) makes it approachable: you can validate the logic without touching real funds. Support for proxy wallets and Gnosis Safe signatures broadens the audience to users who want more security than a raw private key on an EOA.

Who should use this?

Traders already familiar with Polymarket's CLOB who want to systematize weather-based strategies. Researchers backtesting weather-market hypotheses against a local simulation. Developers exploring prediction market arbitrage concepts without building the plumbing from scratch.

Verdict

This is a functional, well-documented tool for a niche but valid use case. The credibility score of 0.8500000238418579% and 301 stars suggest early traction but limited community validation. Documentation is thorough, but test coverage and production hardening are unclear -- start with paper trading and small sizes before committing real capital.
