The area, located on the northern foothills of the Ligurian-Piedmontese Apennines and at the entrance of the Stura valley leading to the Turchino pass, is hilly, tending to mountainous heading south, with plains where agriculture is practiced and where the industries have established their factories near the main connections. The city lies on the confluence of the Stura of Ovada torrent into the Orba river, at an altitude of 186 meters above sea level. The fauna includes badgers, dormice, deer, wild boar, martens, squirrels, hares, partridges, foxes and weasels. There are also nocturnal birds like owls, hawks, kestrels and buzzards. The more frequent fish is trout.
Climate
The climate is temperate with quite marked features of continental climate. Being protected from the south by the south and south-west winds by the chain of the Apennines, the winters have moderate snowfalls: Ovada receives more snowfall than other Italian towns located at the same altitude since the territory of the low Alessandrino and generally in Lower Piedmont, is often home to major inversions that warm southerly winds fail to unseat. Also for this reason, morning temperatures in winter easily drop below 0 °C. The close proximity to the Ligurian Sea, where cyclones often dig deep minimum of low pressure, combined with the orographic lift effect of the Apennines south of Ovada, mean that precipitation proves fairly abundant especially in the autumn months. Spring is often very windy and moderately rainy. Summer in Ovada is the driest season, unlike the rest of the Piedmont. Remaining, even in summer, rather windy, the summer weather in Ovada hardly looks sultry and temperatures only during strong African heat waves exceed 30 °C. In the fall with the return of the Atlantic cyclones the weather is often overcast and rainy, and occasionally the fog appears, although much less than in other areas of Piedmont and the Po Valley. Ovada is also affected for a few days a year of moist air coming from the Ligurian Sea, called Marin, which in some cases can even lead the smell of salt air in these territories and mild temperatures even in winter.
