Polymarket weather markets
Polymarket's daily weather series price tomorrow's high or low temperature for cities around the world. Each day is a chain of density buckets, one or two degrees wide with open ended tails, and the set of bucket prices forms an implied probability distribution over the day's temperature.
Marketlens collects every bucket of every chain, so the full distribution reconstructs at any point in time. If you want to compare market implied forecasts against actual weather models, this is the raw material.
This page lists the weather series in the catalog. For what the weather archive holds and how to pull it, see Polymarket weather market data.

How many Polymarket weather markets does Marketlens have data for?
The archive covers 62,055 weather markets across 106 recurring series, of which 59,068 have resolved. Coverage runs from March 1, 2026 through September 21, 2026.
What data is available for each weather market?
Most markets have full L2 order book history (snapshots plus every price change with millisecond timestamps), trades, and candles; the longest dated books carry full depth snapshots at regular intervals alongside their trades and candles. Every market stores its final resolution outcome. Data is served through the REST API and Python SDK, with bulk Parquet exports for offline work.
How much do these markets trade?
Combined traded volume across the category is $72.7M. Per series volumes are listed in the table on this page.
Can I backtest strategies on weather markets?
Yes. Pass any series slug from this page to client.backtest() in the Python SDK. Execution mode replays the order books tick by tick and fills simulated orders against real depth with queue priority, latency, and fee modelling; Alpha mode replays one bar per market for slower signals over long windows.
Other categories: crypto, sports, esports, or the full catalog.
