despite the often perfect beach-weather in rio, April is actually one of the months with the highest number of wet days, rising to an approximate of 9 and with over 100mm of rain expected as the total.

The temperatures will vary from 22° to 27° celsius, 71° to 80° fahrenheit, and even if the humidity won't be too high, the dew point might range from a low of 20°C - muggy, and get to a high of 25°,  and it is in fact this number what more closely relates to the thermal sensations.

Even when it might not rain, cloudy days are likely, but winds will not amount to more than a gentle breeze.
