Everyone has been there. You head out for a hike or start setting up the backyard grill. Ten minutes later, you’re sprinting for cover as a sudden downpour arrives out of nowhere. Rain is more unpredictable than ever, but thanks to AI, the forecasts just got more reliable.
Since its launch last August, PredictRain, a standalone app developed by the team behind the world’s leading marine weather app, PredictWind, has made a major leap in precision. By integrating advanced AI weather models, the app has effectively doubled the accuracy of its AI-refined forecasts, giving users a new level of confidence.

AI-Refined Forecasts in Your Pocket
For decades, weather forecasting relied on physics-based models. PredictRain has flipped the script by integrating a new approach to global weather forecasting that combines traditional physics-based models with two powerful new AI weather models: PWAi and AIFS.
The AI weather models have a different design from traditional physics-based models, which makes their forecasts unique. Experts around the world have identified that AI weather often outperforms traditional models, which leads to higher accuracy.
The PredictRain app provides AI-refined, hyper-local forecasts and global coverage, delivering precise 6-hour predictions, instant rain alerts, accumulated rainfall insights, and more.
AI Rain uses live rainfall data, delivering ultra-precise updates every 10 minutes to sharpen predictions. In the world of weather, where a storm can develop in the time it takes to find your sunglasses, that quick refresh is the difference between getting soaked and staying dry.
Planning Beyond the Next Hour
Beyond the short-term precision, the reality of outdoor planning often requires a longer view. Whether planning a weekend camping trip or a week-long construction project, it’s key to know what the weather lies ahead.
PredictRain recently introduced a new 9-day Accumulated Rain Map. This feature allows users to look over a week ahead to see exactly how much rain is expected to fall in their specific area, allowing for much smarter decision-making.

Tech That Works for Everyone
Despite the impressive tech running in the background, the app is designed for the everyday person who just wants to know if they should bring an umbrella.
The interface is built around several key features:
- Real-Time Alerts: Receive an instant notification the moment rain is headed your way in the next hour.
- Rain Radar: Visualize real-time rain movement with customizable overlays so you can keep track of exactly where the rain is moving.
- Lightning Tracker: Monitor global lightning activity with real-time strike classification to help you stay safe.
- Climate Data: Access historical rainfall trends so you can plan based on seasonal and location-based insights.
- Satellite Imagery: Combine cloud cover and rainfall data to give you a full picture of the atmospheric context.
Expert Precision
The team behind PredictRain didn’t start from scratch. They are the same team that built PredictWind, the platform trusted by 1.7 million sailors globally, including professional sailors who depend on pinpoint accuracy for their safety and success.
“Our mission has always been to provide the most accurate and reliable weather forecasts,” says Jon Bilger, Founder of PredictWind. “PredictRain is a natural extension of that. We’ve leveraged cutting-edge AI to create a solution that goes beyond traditional models, giving users a powerful tool to plan their lives without being caught off guard.”
With more extreme weather than ever making it harder to trust a standard forecast, and AI showing incredible promise in closing that gap, this is one app you’ll want in your back pocket.
PredictRain is now available for download on iOS, accessible to outdoor enthusiasts and professionals alike. The basic version is free, and PredictRain Pro is available for $29 USD per year. With a paid PredictWind subscription, basic users and above receive full access at no additional cost.
