Windy.com and their app have an ocean current model - how accurate is this for for NZ - in particular for timing of passages around capes? The current model appears to include macro tidal effects since it shows currents changing in sync with tidal oscillations, for example around North Cape or thru Cook Strait. However the model also shows currents passing thru land, so on a micro scale obviously not accurate. But for forecasting effect on currents of tidal changes around capes, seems like it would be useful if reasonably accurate at a macro level.
