Weather forecasts and impact analysis for all Week 18 games
Forecast updated: 48 days ago
Our comprehensive Week 18 NFL weather report provides real-time forecasts for every game, helping you make informed betting and fantasy football decisions. Weather conditions significantly impact game outcomes, with cold temperatures, high winds, and precipitation all affecting scoring, passing efficiency, and play-calling strategies.
Cold weather games (below 32°F) typically see 10-15% reduced passing efficiency as quarterbacks struggle with grip and accuracy. Wind speeds above 15mph disrupt the passing game and make field goals more difficult. Rain and snow lead to conservative, run-heavy game plans with increased fumbles and lower scoring totals.
Our advanced percentile system compares each Week 18 game against thousands of historical NFL games to identify extreme weather conditions. Higher percentiles indicate more severe conditions relative to typical NFL weather patterns.
Temperature percentiles range from coldest (0th) to hottest (100th). Wind percentiles show calm (0-20th), normal (20-50th), moderate (50-80th), and extreme (80-100th) conditions. Precipitation intensity is measured as light (0-25th), moderate (25-75th), or heavy (75-100th) compared to all rainy/snowy games. Dome games eliminate weather variables entirely.
