Jaco immediately starts with good news: “Especially in September there is a chance of beautiful late summer days. On average, September still has seven warm days with maxima of 20 degrees and more. That could just be more now. If the wind blows from a southerly direction, it can even get warm in summer with temperatures around 25 degrees. But it is not yet clear whether the wind will also come from the south.”
Softer than usual
According to the meteorologist, the weather forecast for October and November is still very uncertain. The weather models show that it will also remain milder than normal in those months. “The usual changeable autumn weather is therefore most likely for these months, but with slightly higher temperatures.”
Finally, an important side note: seasonal models only sketch a rough trend for the monthly average air pressure, temperature and precipitation. Even an average warm month can have a cool week and vice versa.
Sun and rain in Zoetermeer
The days get shorter in the fall and you notice that in Zoetermeer. Jaco: “In September, the sun still shines for 40 percent of the daylight period, in October this drops to 36 percent and in November we only see the sun for 25 percent.”
According to Jaco, there is about 75 millimeters of rain in all three autumn months, but there is a difference per month. In September, these are often short-term heavy showers, while later in the autumn it often rains for a long time (moth). It rains 7 percent of the time in September, 8 percent in October and 10 percent in November.
