Winter 2026 in Mato Grosso do Sul: Above-Average Temperatures and Below-Normal Rainfall

Winter 2026 in Mato Grosso do Sul is expected to bring above-average temperatures and below-normal rainfall, according to the state's Weather and Climate Monitoring Center (Cemtec). The season officially begins on June 20 and will be characterized by prolonged dry spells, particularly in July and August, which are traditionally the driest months.

During the three-month period, residents should prepare for extended dry weather, low humidity, and heightened health risks for vulnerable groups such as children, the elderly, and those with respiratory conditions. While winter typically brings colder mornings, the overall trend points to higher-than-average temperatures across most of the state.

Despite the warmer outlook, cold air masses may still cause sharp temperature drops, especially in southern Mato Grosso do Sul, where isolated frosts are possible. The dry conditions also increase the risk of wildfires, prompting authorities to urge caution and avoid the use of fire in both urban and rural areas.

In the agricultural sector, the lack of rainfall requires constant monitoring of soil moisture and pastures. For city dwellers, health recommendations include staying hydrated, avoiding prolonged sun exposure during the hottest parts of the day, and taking extra care with respiratory issues. The first regular rains are expected to return only in the spring, between late September and early October.
