History and ethos
Kevin joined the Earthsat Cropcast group in 1980, developing the early crop-weather yield models for corn, wheat, and soybeans, then extending them to cocoa, coffee, and sugar. When deregulation opened natural gas and electricity trading desks in the late 1980s, he built the first weather services for that market. By the late 1990s, that work had expanded to cover the weather derivatives industry.
Marcus Weather was formed in 2001 to serve commodity hedge funds and food processors directly. At its core is a privately developed weather database built for one purpose: commodity analysis. Correlated datasets let us quantify global crop yield and energy demand objectively, and identify the outliers that matter. Clients rely on us to anticipate the shift before the new weather narrative arrives.
Relationships measured in decades, not quarters.
Marcus Weather service is, in a word, superlative. Their insight is intelligent and timely, especially for trading commodities.
Marcus Weather uniquely and quantitatively combines past weather, forecast weather, and importantly, a deep knowledge of plant agronomics. Their models link weather to yield in a way that is both differentiating and easy to follow.
Your service continues to earn its spot in our research services. The combination of timely weather analysis, commodity-specific insight, and an objective view of developing risks makes Marcus Weather a valuable part of our decision-making process.
