Weather and climate in Santo Tomas
If you're keen to soak up the sun, have a splash, and relax in the outdoors until after dark, the best time to book holidays to Santo Tomas is between mid-June and mid-September, when night-time temperatures often remain above 20°C by the coast. It's normally comfortable enough to swim in the sea from about June until October, with the water temperature typically peaking at around 26°C in August. Even in October, the sea temperature is normally in the low 20s. As a comparison, this is still much warmer than the average sea temperature along the England's South Coast in July.
