What this chapter covers
This is chapter 27 of our 32-part series on building a Polymarket trading bot. We cover the topic in depth across the sections below. Body content for each section is being written and rolled out chapter-by-chapter; FAQ answers and references are already complete and reflect production experience from running our own trader.
Weather as a tradeable signal
Hurricane markets: NHC data
Daily max temperature: NWS data
ENSO (El Nino/La Nina) cycles
Latency: weather updates are slow (good for retail)
Risk: forecast model error tails
Code: pull NOAA hurricane data and adjust position

Frequently asked questions
What weather markets does Polymarket offer?
Hurricane landfall (where and when), seasonal hurricane count, daily max/min temperature for major US cities, ENSO state (El Nino vs La Nina vs Neutral), monthly rainfall totals. Polymarket also occasionally lists novelty weather markets (snow on Christmas, etc.).
Where do I get weather data for a Polymarket bot?
NOAA (noaa.gov) for official US weather data including hurricanes (NHC.gov), temperature (NWS.weather.gov), and ENSO (Climate Prediction Center). All free and well-documented APIs. ECMWF for European forecasts. International: WMO and national met services.
Can a retail bot beat the market on weather?
Sometimes. Weather is one of the few categories where retail can have an edge because most quant traders ignore it and the official forecasts are rarely real-time-priced into the market. A bot that pulls NHC updates every 30 minutes during hurricane season often catches mispricings.
What is the latency budget for weather markets?
Slow - minutes to hours, not seconds. NHC updates are issued every 6 hours during quiet periods, every 3 hours during active ones. NWS daily forecasts update twice a day. This is the rare Polymarket category where commodity-cloud VPS is fully sufficient.
What is the worst case for a weather bot?
Forecast error blow-up. The official forecast says a hurricane will hit Miami; you go long Miami-landfall. The hurricane veers and hits Tampa. Hard rule: never bet more than 5-10% of bankroll on any single weather event. Forecasts are wrong more often than they look.
Are there weather markets year-round?
Yes, but volume is seasonal. Hurricanes peak June-November (Atlantic basin). Temperature markets continuous. ENSO updates monthly. Novelty markets (snow, rainfall) cluster around the relevant season. A year-round weather bot uses different markets in different months.
