Resolution criteria

This market resolves to YES if the Estonian Environment Agency (Riigi Ilmateenistus) officially records any snowfall—including snow (lumi), snow grains, or sleet (lörts)—at any of its official meteorological monitoring stations in Estonia during the period of September 1, 2026, through September 30, 2026, inclusive.

Otherwise, this market resolves to NO.

Verification details:

• The primary source of truth is the Estonian Environment Agency (ilmateenistus.ee).

• Resolution will be determined using the official September 2026 climate summary (usually published in early October) or real-time daily observation data from the agency.

• Any officially recorded precipitation categorized as snow or sleet, even in trace amounts (jäljed), will trigger a YES resolution.

• If the market creator intended a different year than 2026, they must edit the description to specify the year before the end of the month. Otherwise, the market will resolve based on the September 2026 timeframe.

Background

September is a transitional autumn month in Estonia, featuring average daily high temperatures of around 15°C (59°F) and lows of 9°C (48°F). The first snow typically does not arrive until late October or November. While the occurrence of snow or sleet (lörts) in September is historically rare, cold fronts from the north can occasionally bring brief wintry precipitation to the Baltic region in late September, which is tracked by the Estonian Environment Agency's network of observation stations.
