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.

Wind predictions

Thanks to facebook friends I have found two new websites that will be helpful predicting wind flows for our flight across from Mozambique to Madagascar in July.

Windytv.com and earth.nullschool.net both offer a moving map which shows the wind and other weather indications at different altitudes. You can therefore check to see what would be the best altitude to fly at to minimise any headwinds and hopefully fly with the wind. We will be crossing the Mozambique Channel, flying east from Vilankulos in Mozambique to Toliara in a 4 1/2 hour flight (or more if there is a headwind.) The aircraft carries 6 1/2 hours fuel, and any headwind would seriously impact on the range we can fly.
