Multi Weather lines up official agency forecasts and numerical model output on one screen so you can spot where they disagree at a glance. Instead of trusting a single forecast, compare the official JMA forecast with the output of several models to make on-site Go/No-Go calls faster. ■ Official forecasts and model output together See official forecasts from JMA, MET Norway, Apple and NWS (US), alongside numerical model output from GFS, ECMWF, ICON and more — whichever are available for your location — overlaid on one timeline. Weather symbols (each agency's or model's own classification), precipitation (amount/probability), wind, temperature, cloud cover and humidity, side by side. Data sources: JMA, NOAA GFS, NWS (US), ECCC (Canada, GDPS), MET Norway, ECMWF (IFS, AIFS), ICON model (DWD), HARMONIE model (DMI), Apple Weather. ■ See the disagreement Every source is drawn on the same graph, so the hours where forecasts and model output split are visible at a glance. The way professionals read model differences — in seconds, for anyone. ■ Evidence export (CSV and PDF) Export the comparison as CSV or PDF to share. Hand a clear basis for a stop/postpone decision to clients or contractors. ■ Jump to other services Open JMA, tenki.jp, Yahoo Weather or Windy for the exact spot you're viewing, in an in-app window. ■ Built for the field For construction, civil works, ports, surveying, drones, film shoots, fishing and hiking — anything weather-dependent. Note: This app does not make its own forecast. It shows official agency forecasts (e.g. JMA) and numerical model output as provided, side by side. Numerical model output is not a forecast and may contain large errors. Final decisions are your responsibility. The first 30 days are completely free. To keep using all features afterward, an auto-renewing subscription (monthly or yearly) is required — cancel anytime.
