Most weather traders I’ve covered are farming temperature markets.
But this account found a corner almost nobody touches:
Rainfall.
A London-focused Polymarket precipitation trader with a 100% win rate in that category.
His edge is simple:
Instead of fighting everyone in temperature ranges, he trades “how many mm of rain London gets.”
These markets are thin, and often barely priced.
His best trades:
$143 → $3,489
London May precipitation <5mm
Bought Yes at 4¢
$20 → $390
London May precipitation 25-30mm
Bought Yes at 2¢
$9 → $200
London April precipitation 50-60mm
Bought Yes at 2¢
Total profit: $4,018
Total volume: $43,779
The interesting part:
His win rate in temperature markets is only 39%.
But in rainfall markets, it’s 100%.
Temperature keeps him at the table.
Rainfall is where he prints.
While everyone crowds into the same weather markets, he walked into the room almost nobody noticed.
