Wind and weather for our Mozambique Channel crossing next Sat

Here is the predicted wind and weather for our 5 hour flight over the Mozambique Channel to Madagascar next Saturday. The prediction shows a light cross-wind/tailwind for the flight at 2 500 ft. If I adjust the map for different altitudes we are able to pick the most favourable wind for the crossing as it varies considerably every thousand feet or so. 

Unfortunately the rain and cloud cover on the eastern side of Madagascar after our arrival is not looking good and we might have to divert to the west coast for the fairer weather... a bit difficult as we have accommodation bookings on the east.
