WEATHER 4D LITE / WEATHER 4D ROUTING
WEATHER 4D Lite 16.99 € - iOS / Free - Android : basic version for the general public for multi-activities.
WEATHER 4D Routing - 37.99€ iOS only - advanced version for maritime navigation with routing module, satellite phone query management, GRIB file history management.
This well-known application has recently been revised and now benefits from a new interface derived from the "Routing and Navigation" version (see in navigation applications).
Weather4D Lite is provided as standard with the GFS global forecast model at 0.25°, 0.5°, 1° and 2° resolutions. It also provides paid subscription access (€37.99 per year) to 38 high-resolution weather models including NAM, COAMPS, WRF (USA), GEM (Canada), ARPEGE Europe, AROME, AROME HD (France), AROME (DOM-TOM), as well as WW3 wave and MERCATOR OCEAN current models and MFWAM and NCOM current models.
The application allows you to create custom zones on the globe and select the characteristics of the GRIB files to download: choice of data, resolution, periodicity, file size, etc. The GRIB files are downloaded from the vendor's own servers in wifi or 4G, and can also be obtained by satellite (native support for Iridium Go)
Weather forecasts are displayed in one or two (split) windows (iPad only), offering several display combinations of the same area: weather forecast and wave or current forecast, comparison of different models. The two windows can be dissociated to display the same area at different scales.
The Routing version adds the following features to the Lite version:
- route import from any application that can export/import routes (iNavX, iSailor) and visualize the weather according to the boat's progress
- import of speed polars with management of multiple sail combinations
- routing for regatta sailing or mixed sail +motor for cruising, with options (waves, max wind etc - see this video)
- Resume routing during navigation (from the ship's position)
- export of optimized routes to any application that can export/import routes (iNavX, iSailor)
To know more about it:
- Weather4D multimedia User Guides to download for free in Apple Books app.
SAILGRIB
Free / Paid (€9.49) Android only
Sailgrib is an application that allows you to load and view grib files from different sources (SailGrib, SailDocs, Great Circle, MeteoConsult, GMN, ...) by direct download or email. The GFS, WW3, COAMPS, NAM, GCWF, MyOcean (IBI, Baltic, Global) models are available to visualize wind, pressure, clouds, rain, air temperature, air stability, wave height and direction and finally ocean and tidal currents.
The application also allows you to download grib files with a satellite phone using the iridium Go, or the wXa-122 Optimizer.
The paid version allows you to obtain up to 16 days of forecasts (GFS model), the free version is limited to 48 hours.
SQUID MOBILE
Freet iOS - Android (in-app purchase)
Squid Mobile is an application from weather specialist Great Circle based in Belgium. It offers weather data with global and regional coverage for free or paid (free access to GFS, on a paid subscription of 1 week 5.99€, 1 month 9.99€ / 3 months 18.99€ / 1 year 33.99€ for HIRES high resolution models). It provides access to forecast data covering all regions of the world.
Its features :
- Download of GRIB files by wifi, 3/4G or satellite link (Iridium Go compatible)
- Animated display on the map
- Meteogram
- Online routing (integrates the modifiable polars of many boats) on a Google Earth or vector map background
export routes to a compatible app (like iNavX)
The essentials are there, but the ergonomics are perfectible and the display is a bit rustic, especially compared to Weather4D, which is certainly worthwhile but much richer and more ergonomic. The need for online access seriously limits the possibilities of routing at sea. Suitable for those who want to approach routing in GFS or with a short-term subscription without spending too much money.
WINDY
Free (Donationware) iOS - Android
Windy is a tool to display weather forecasts. This fast, intuitive, detailed and accurate application has gained the confidence of professional pilots, paragliders, skydivers, surfers, kiters, sailors, fishermen, storm chasers and weather geeks, as well as many government, military and rescue teams.
Windy offers you all the most widely used weather forecast models in the world: the global ECMWF and GFS models, as well as the local, NEMS, AROME and ICON (for Europe) and NAM (for the United States).
Wind, rain, temperature, pressure, waves or CAPE index, with Windy you have all the practical weather charts at your fingertips.
Global composite satellite views are created from NOAA, EUMETSAT and Himawari sources. The update frequency is 5 to 15 minutes depending on the area. Doppler radar covers a large part of Europe, America, Asia and Australia.
Windy is free but allows you to make "donations" in integrated purchases.
METEO CONSULT MARINE
Free - iPhone / iPad / Android
iPhone version: complete weather app, user-friendly with a lot of datas (area selection, visual display of areas with specific weather conditions, swell prediction, sea state, temperature, pressure, high tide...). All these predictions are available over 10 days !
iPad version: design is totally different, with for example, a customizable landing page. Some restrictions, you have to use the iPad in landscape mode, no animations for weather which makes it difficult to evaluate changement over a specific location. It doesn't accept files import export so you have to charge datas just before boarding over 3G.
METEO FRANCE
Météo France is general weather app, nevertheless it proposes marine weather forecast over all marine areas of Europe. Same weather forecast as the one diffused on radio and Navtex.
Of course, you need an internet connexion to update forecast. Very useful for coastal navigation.
WEATHERTRACK
10,99 € - iOS
Also complete weather app for pro and normal users.
Features list is impressive (visible on iTunes) with, as example, forecast up to 16 days (over 6 days, it's not a forecast it's a tendency), rain radar map, a "Grib Robot" feature that optimises your satellite
The list of features is impressive (see the description on iTunes) with e.g. forecasts up to 16 days (over 6 days, it's more a trend than a forecast), rain radar maps , a "Grib Robot" feature to optimize your satellite files download from multiple servers, possibility of creating a background route on a vector land map.
However the application is far less aesthetic and ergonomic than Weather4D, and if it allows to draw a route on the map, it does not routing calculation. Many features are only available through integradted purchases ranging from 0.89 € up to € 41.99 €.
