-40 Weather vs Swellwire

-40 is the one temperature where Celsius and Fahrenheit are exactly equal. It is also a weather app that shows you both scales at once, so you never have to convert, with radar built the way the professionals build it. BOTH SCALES, ALWAYS Every temperature appears in °C and °F side by side. Choose which one leads in Settings. RADAR THAT RUNS ON YOUR PHONE Most weather apps show you radar. -40 Weather runs it. Instead of downloading finished pictures of the weather, the app downloads compact radar data built from NOAA measurements and draws the map on your device. Pan and zoom instantly, watch a smooth animated loop, and see where storms are heading next. Storm tracks, warning areas and storm reports are layered on top, and you can zoom in for high-resolution detail. Covers the United States and Canada. YOUR CITIES, ONE SWIPE APART Save as many places as you like and swipe between them. Add your current location or search for any city in the world. FORECASTS AT A GLANCE Current conditions, feels-like, highs and lows, a 7-day forecast, hourly detail, wind, precipitation, and sun and moon times. First light and last light show the usable daylight before sunrise and after sunset. Morning, midday and evening cards suggest what the weather feels like, from sweater weather to beach weather. ONE TAP TO THE DETAILS Tiles on the home page show live values and open hourly, precipitation, wind, moon, air quality and pollen, and the Field Guide. WEATHER ALERTS See active alerts from the National Weather Service right on the main screen, with optional notifications. AIR QUALITY AND POLLEN Check air quality and a 5-day pollen forecast covering tree, grass and weed pollen. ON THE WATER Marine conditions, tides, and estimated fishing windows for coastal and inland waters near you. These are estimates and are not for navigation. BUILT TO SIP YOUR BATTERY Location uses a coarse fix instead of constant GPS tracking, and weather alerts arrive by push instead of the app checking in on a timer. DYNAMIC ISLAND AND LIVE ACTIVITIES Optionally keep the current temperature on your Lock Screen and in the Dynamic Island. MADE YOUR WAY Pick a color theme, including one that shifts with the temperature, and choose metric or imperial units. The bottom bar uses Liquid Glass on iOS 26. Works on iPhone and iPad. Weather data comes from OpenWeather, the National Weather Service and NOAA, Open-Meteo, Google and other sources listed in Settings. Forecasts and alerts are for general information and are not a substitute for official warnings.

Swellwire turns the world ocean into a planner. Spin the globe, drop into any coast, and read the swell, wind, and weather in seconds—right now, tomorrow, or two weeks out. WHAT YOU GET • Interactive 3D globe with live wave-height, wave-energy, wind, and temperature overlays. Pan, pinch, and tap to explore any shoreline on the planet. • Surf spot forecasts: wave height, period, direction, wind, and a clean at-a-glance read before you commit to the drive. • Buoy data from major coastal networks, surfaced inline on the same map you're already using. • Search any surf spot or NOAA buoy by name and jump straight to its forecast. • Favorite spots sync across devices, so your home break, your travel list, and your weekend backup are all one tap away. • Wave-energy color legend lets you compare a heavy four-foot day against a soft five-foot day at a glance. FREE OR PREMIUM Free includes the full globe, every overlay, and a 7-day forecast for every spot. Premium extends every forecast to a full 16 days — long enough to see swell windows before they're obvious to everyone else. WHO IT'S FOR Surfers planning the next session, the next trip, or the next swell. Sailors, kiters, foilers, divers, and anyone whose day depends on what the ocean is actually doing. WHY A GLOBE INSTEAD OF A FLAT MAP Swell doesn't care about map projections. A storm in the South Indian Ocean lights up reefs in California a week later — on a globe you can see why. Watch a long-period swell wrap around continents in the wave-energy view and a forecast starts to read like a story.
