🌦️ Will It Rain On My Parade?

NASA Space Apps Challenge 2025 - Harohalli Local Event
Team: Bluesoft

Know the Odds Before You Plan Your Day

A web application that helps users plan outdoor events by analyzing historical weather patterns and providing probability-based forecasts using NASA Earth observation data.

🎯 Problem We Solved

Traditional weather forecasts only provide short-term predictions (7-14 days), leaving event planners uncertain about weather conditions for future outdoor events. Our solution addresses this gap by leveraging decades of NASA Earth observation data to provide probability-based weather risk analysis for any location and date worldwide.

Key Innovation: Instead of predicting exact weather, we calculate the historical probability of adverse weather conditions occurring on specific dates, empowering users to make data-driven decisions about outdoor event planning.
