Mercury Weather

Version 3.7 • Sep 11, 2026

Mercury is ready for iOS 27! This is a big one: deeper Siri integration and new extra-large widgets. Plus, a more flexible Trip Forecast, new Tide widgets, and Monthly Averages comparisons to help plan your next adventure. SIRI INTEGRATION Ask Siri about upcoming or past trips, or add a new trip destination to Mercury. Natural-language requests and conversational follow-ups make it easier to plan your travels. EXTRA-LARGE WIDGETS On iOS 27, a new extra-large widget brings current conditions, upcoming rain, and hourly and daily forecasts together in one place. FLEXIBLE LAYOUTS The user interface now adapts as you resize its window in iPhone Mirroring. TRIP FORECAST 2.0 Spend the morning in one place and the afternoon somewhere else, or plan a multi-stop road trip. Add precise trip times and multiple stops in a single day, with the weather for each destination appearing in your daily and hourly forecasts, including widgets and Apple Watch. TIDE WIDGETS Keep an eye on the tides from your Home Screen or Lock Screen. Choose a tide station to see the current tide height and upcoming highs and lows. The Tide widget also supports the new extra-large size on iOS 27. Available for supported coastal areas in the U.S. and Canada. COMPARE MONTHLY AVERAGES Compare temperatures, rainfall, sunshine, and daylight between two places throughout the year. See how a destination compares with home before planning your next trip. OTHER IMPROVEMENTS Clearer weather warning colors and more reliable forecast refreshes and radar loading. Kai & Malin
