I think these factors might be affecting the ride:
1. Fuel is 95 Octane grade (the cheapest available here).
2. Engine is 1.3L
3. Ambient temps are always about 45 Deg Plus in this season.
4. AC is usually on but when I get 32 mpg I am doing mostly freeway without AC (AC on for 30% of time)
5. I ride alone with no luggage.
6. Tires are at 38 psi.

Any ideas??
Could fuel density be an issue?

That would be about average for Yaris here in the USA. The factors you listed would have some affect on your MPG's. I know hot temperature is better than cold temperature for better mileage FE.

You did not mention driving style and other environmental conditions? This I believe is everything for getting higher gas mileage. Important factors are...

1. What speed do you maintain on highway and city driving?
2. Flat vs mountain terrain travel?
3. Duration and miles/kilometers of travel? Short or long travel?
4. Slow start vs fast start?
5. Breaking glides and neutral glides?
6. Average RPM during drive and travel?

These are just some of the driving styles and environment conditions that would have an affect on your mileage.

I would like to mention that here in my State, I'm fortunate enough to be able to get non-ethanol gas... Average is around 3 MPG better than ethanol gas...

Cheers!
