Dampen your sheets before hanging them in front of your windows and if needed repeat the process, especially on the sunny side.
The evaporating water will create a very effective cool layer of air between the sheet and the window as well as preventing the sun getting to window glass. It does REALLY work! The cooler you can keep your place, the less other measures will be needed - and you profit as well.
I have managed to keep indoors temperatures on 35 C day (our current local record) ca. 10 C lower that way.
Be aware that the real killer won't be so much Monday but Tuesday because of the tropical night when the house won't cool down at all overnight.
Don't use just one measure, use them ALL - as many as you can.
