I want to know the answer to the following question:
Which current affects Paris' weather?
All the background I'm provided with is that "Some years have even witnessed long periods of harsh summer weather, such as the heat wave of 2003 when temperatures exceeded 30 °C (86 °F) for weeks, surged up to 40 °C (104 °F) on some days and seldom cooled down at night.". Is that enough to answer the question?
Answer: no
