This is the start of the hot season, when noon time temperatures can go up to 33 degrees celsius, morning lows of 26 degrees Celsius. For the most part expect sunny weather, with short showers. Bring summer clothes, but a light sweater or shawl for women, sports jacket for men in case you attend the theater or may visit an air conditioned restaurant with a very cool air conditioner. Ditto for traveling on Metro Bus.
