November in
Recife is characterized by quite balanced weather conditions. On the one hand, rainfall hits an annual low at 36mm (1.42") signifying predominantly dry conditions. On the other hand, with daylight hours increasing to 12.5, beach activities and sightseeing cater to perfect utilization of the longer days. Correlating with the drop in rainfall, the sunshine hours as well sees an increase, aiding the enjoyment of the dry days. The sea temperature, too, begins to climb, heralding the return of warmer waters.
Temperature
November is marked by an average high-temperature of a tropical 30.1°C (86.2°F), almost identical to the preceding month. An average low-temperature of 21.9°C (71.4°F) is recorded during the nights in November.
Heat index
November's mean heat index is estimated at a sweltering 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Adopt all important safety measures, unprotected skin may burn rapidly. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. After a swim or an outdoor workout, generously apply and reapply a broad-spectrum SPF 30+ sunscreen. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
