Top 5 Cities: Nassau, Freeport, West End, Cooper's Town, and Marsh Harbour

This month in numbers

June 2026 saw the Bahamas record its 8th warmest June on record, with an average temperature of 27.58°C, an anomaly of +0.9°C compared to the 1961–1990 baseline. Globally, June 2026 was the 3rd warmest June for land temperatures, with an anomaly of +1°C.

What changed

The period of April to June 2026 was the 6th warmest such period on record for the Bahamas, with an average temperature of 26.31°C, an anomaly of +1°C. This continues a trend of warmer-than-average conditions, with 2025 being the 2nd warmest year on record for the Bahamas. The long-term trend for the region shows a warming of +0.95°C compared to the 1961–1990 baseline.

What’s driving change?

The elevated temperatures in the Bahamas are consistent with the broader global warming trend, with land warming faster than ocean. The current El Niño Southern Oscillation (ENSO) phase is also contributing to drier conditions and increased heat in the region. In June 2026, the Ministry of Health and Wellness and the Department of Meteorology issued a heat health bulletin, warning of heat index values between 102 and 110 degrees Fahrenheit across several northern and northwestern islands, including New Providence, Grand Bahama, and Andros. This early onset of summer-level heat stress has also been linked to power outages in early June due to strain on the electricity grid.

Looking ahead

The Bahamian Department of Meteorology forecasts a below-average 2026 Atlantic hurricane season, with approximately 11 named storms and between one and three hurricanes expected, largely due to the effects of El Niño. However, residents are urged to remain vigilant as warm sea temperatures can still propel hurricane formation.
