This could be because the strong night rain and/ or an early morning watering washes fungal spores off the surface of leaves of plants.
Different fungal spores need different “ moist” time period to develop and cause the disease: some only need 4-6 hours, a lot of them need 6-8 hours or longer.
So if night rain washes off the dew and spores off the leaves and than a sun or wind dries out leaves- the existing spore can not develop, so the countdown for next spore starts again
So your night rains actually may help stop fungal diseases sometimes
