There was a nice mix of sunny and cloudy days, with a few showers. It was perfect for exploring nature.
SanderThe sky was bright blue and the sun was almost always shining. It rained occasionally, but it was refreshing. Too warm for some active sports, ideal for relaxing activities such as swimming.
KarinAugust in San Marino was quite pleasant. Warm but not muggy during the day, ideal for relaxing walks. It got pleasantly cold at night. The rain was very light.
SjoerdSometimes it can rain and the sun doesn't show much. This contributed to a cozy winter atmosphere, but don't expect sunny vacation weather.
JudithAlthough it was extremely scenic, it discouraged outdoor activities. Winter coat and boots are essential!
