Cuba Climate – June 2026 Update

Top 5 Cities: Havana, Santiago de Cuba, Camagüey, Holguín, and Guantánamo

This month in numbers

Cuba experienced its 4th warmest June on record in 2026, with an average temperature of 27.77°C, marking an anomaly of +1.3°C above the 1961–1990 baseline. The three-month period from April to June 2026 also ranked as the 5th warmest on record, with an average of 26.89°C, an anomaly of +1.2°C. Globally, June 2026 was the 3rd warmest on land, and the April–June period was the 2nd warmest on land.

What changed

Cuba's consistently warm temperatures this past quarter align with a broader warming trend, as the country's latest full-year average temperature in 2025 was 26.19°C, making it the 2nd warmest year on record. This contributes to a long-term warming trend of +0.95°C compared to the 1961–1990 baseline. The Caribbean region as a whole has been experiencing unusually warm sea surface temperatures, contributing to higher air temperatures and humidity.

What’s driving change?

The primary driver of Cuba's current warming trend is the ongoing weak El Niño event, which is forecast to strengthen significantly in the coming months. El Niño typically leads to warmer-than-average conditions and drier weather in the Caribbean basin, increasing the probability of drought and extreme heat in Cuba. This is compounded by the general effect, where land areas heat up more rapidly than the surrounding waters. Cuba is currently facing a severe drought, with 62% of the national territory affected as of March 2026, and water reserves at their lowest level since 2015. This further intensifies heatwaves as the ground cannot cool itself through evaporation. Additionally, a severe local storm hit Guantánamo in June, bringing intense rains, hail, and strong winds up to 104 km/h, causing damage to infrastructure, including solar panels.

Looking ahead

The strengthening El Niño is expected to bring a higher probability of drought conditions during Cuba's rainy season (May to October) and warmer-than-usual summers, with a 63% chance of the phenomenon reaching "very intense" levels between November 2026 and January 2027.

Shifting Seasons

Wet / dry seasonsKöppen Aw · Tropical

Cuba doesn't have a warm/cold cycle - its monthly temperature range is only 4.8°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 6× as much rain as the driest). So we track how the wet season has shifted instead.
