Average daytime temperatures during this time stay within the 24.3°C - 27.2°C range, while maximums often reach 28-32°C. Due to high humidity and heavy rainfall, especially from June to September, the heat can feel more intense. Temperature fluctuations between day and night are less pronounced during these months than in the dry season, averaging about 6-10°C.

A characteristic feature of this period is the significant daily temperature range, which can reach 10-15.5°C, especially from February to April.
