Field tools
Our own three-month temperature and precipitation outlook for every climate division in the lower 48, issued monthly and checked against what actually happened. Seasonal forecasts tilt the odds rather than predict the weather, so every past outlook stays up beside its verification. Data through August 2026.
Temperature, 18 seasons
75%
of calls verified; 3% came out the opposite way
Precipitation, 18 seasons
50%
of calls verified; 18% came out the opposite way
A blind guess
33%
of calls would verify, and 33% would come out the opposite way
A call is a lean of 40% or more toward one of the three categories. Over the longer test period 2012–2025, this method verified 59% of temperature calls (13% opposite) and 49% of precipitation calls (19% opposite); the official NOAA outlook scored 59% (14%) and 45% (24%) on the same seasons and places. 2025 and 2026 were unusually warm across the country, which makes warm calls verify more often than the long-run rate.
Each season is compared with the 1991–2020 normal for that place and time of year, split into thirds: below normal, near normal, above normal. The forecast map shows which way the odds lean and by how much (dark red: a strong lean toward above-normal temperature; dark brown: toward below-normal precipitation; grey: no lean). The observed map shows which third the season actually landed in. “Verified” means the favoured third happened; “opposite” means the other extreme did.
