How often are Chicago trail conditions updated?
Loam models conditions hourly against current weather, so a verdict here reflects today rather than a seasonal guess. Each network's own page carries the exact time its verdict was last computed.
What are these conditions based on?
Each verdict comes from recent rainfall, the network's own soil type, its terrain (slope and aspect), and tree cover, run against live weather to estimate how wet and firm the ground actually is. These are modeled estimates, not rider reports, and an official trail closure always takes priority over the model. See how the model works.
