In June and September, the weather in northern Portugal is generally warm, dry and sunny, with temperatures in the day ranging from 65°F to 90°F. Evenings and mornings cool down to the low 50s and 60s. Water temperatures can vary, but should hover around 70°F to 75°F, which some of our guests find a bit chilly, and others find refreshing. There is always the possibility of wind and even a light rain shower on the river.
Together, Natural Habitat Adventures and World Wildlife Fund have teamed up to arrange nearly 100 nature travel experiences around the planet, while helping to protect the magnificent places we visit and their wild inhabitants.
