The barometric pressure in São Luís is quite unique due to its location near the Atlantic Ocean. This proximity to the ocean affects the air pressure constantly. The pressure changes frequently throughout the day, depending on the tides and wind direction.
São Luís is surrounded by the Atlantic Ocean to the north and vast wetlands to the south. The ocean brings moisture and warmth to the city, influencing the pressure. The wetlands, known as the Baixada Maranhense, are low-lying and flat, allowing winds to blow freely and rapidly change the pressure.
The combination of ocean and wetlands creates a microclimate around São Luís, making it prone to rapid changes in pressure. This, in turn, affects the weather patterns in the city. The weather can change quickly, with sudden rain showers or changes in temperature.
