Plan Outdoor Activities Around the Weather
Reloadium Weather is an AI-powered planner that analyses a full week of hourly forecasts and tells you exactly when conditions will be best for your favourite outdoor activities — whether that's hiking, surfing, cycling, fishing, stargazing or anything else.
Add your locations, pick your activities, and let Gemini AI scan 168 hours of real-time weather data to surface the top time windows — complete with the expected duration of optimal conditions, grounded temperature, wind, precipitation and cloud-cover readings hour by hour.
Key Features
AI-Powered Time Recommendations
Gemini AI scores every candidate window across the coming 7 days and returns the top 3 slots per activity, ranked by a weather suitability score and enriched with a plain-language reason.
Duration of Optimal Conditions
Not just the best start time — the AI also estimates how many consecutive hours conditions will stay optimal, so you can plan the full length of your outing.
Grounded Hourly Data
Every recommended slot comes with an hour-by-hour strip showing real temperature, wind speed, precipitation probability and cloud cover from Open-Meteo.
Seven-Day Forecast Curves
The weekly forecast displays smooth sparkline curves for temperature (amber), precipitation (blue) and wind (green), so you can read the week at a glance.
Multiple Locations
Track as many cities as you like. Each location has its own independent activity list, analysis history and weather cards.
Flexible Units & Time Formats
Switch between °C/°F, km/h/mph and 24h/AM-PM directly from the settings panel in the header. Preferences are saved locally.
Multi-Language Support
Available in English, French, German, Turkish, Polish and Spanish — including localised preset activity names.
Analysis History
Every AI run is saved locally so you can compare conditions over time and revisit past recommendations without burning credits.
Share & Export Analyses
Send any result to a friend with a single tap — the analysis is compressed into a shareable URL. Recipients see the same ranked slots with live weather data. You can also export to Markdown, add the window to Google Calendar or download an .ics file.
