scrim1971, if I knew what the weather was going to be 10 days from now, I'd be very rich.
Changes are that it will be hot and that every now and again there will be a tropical shower, perhaps with the odd thunderstorm thrown in. Mornings will be still with little wind and around 11am, a seabreeze will spring up to keep things a little cooled down.
Normal summer weather for this time of the year for us - it has just been a little hotter than usual.
Enjoy your trip!
