New PredictCurrent app
« on: 06 May 2024, 16:43 »
There’s an interesting new app from PredictWind called PredictCurrent.  So far it’s only available on Apple devices (but not my elderly iPad).  They offer a free 2-week trial.

It gives a clear map-based graphical indication of forecast sea currents, hour by hour.  This is particularly useful for planning sailing in light winds or to motor with an electric outboard, which struggles against strong currents.  I’ll be trying it out shortly in the Outer Hebrides, where the tidal currents between the islands can be strong.

The app is not perfect as, so far at least, it doesn’t cover narrow passages like the Menai Strait and the Swale, where information on currents is crucial.

It also gives wind speed and wave height forecasts and an indication of sea temperature.  Anything below 14°C is shown as a uniform purple colour on the map, which means that at the moment the whole sea area from the UK to the Arctic is the same colour.

The PredictCurrent app was useful on my trip up to Barra in the Outer Hebrides to plan which direction to turn for the day and what time to plan to return, making best use of currents.  Also to see the timing of the fiercest currents in the sounds between the islands.  Particularly on the several days when there was little wind and I had to rely on my low horsepower eProp electric motor to get anywhere.

However, the app’s cost of £29 a quarter is excessive and I have cancelled at the end of my free trial period.  Other apps (Navionics, Savvy Navvy) provide more or less the same tidal information in a slightly less accessible form.
