October brings a massive 11" (279mm) of rain in the Northern Mariana Islands, and there is a rare day in the month that does not receive precipitation. The cloudy days limit visibility on the seas, and the slow tourist season affects the cruise business. The average temperatures remain in the range of 75°F (23.9°C) to 84°F (28.9°C) as the conditions remain sticky during both days and nights. Extreme temperatures are absent on the islands, and the record high for October is 88°F (31.1°C). Keep in mind that the sun rays are intense whenever they break the cloud cover. It is prudent to carry both a hat and a raincoat in the rainy season. Water activities see few takers, with the rain often playing a spoilsport. A few people visit Saipan for its history, museums, and monuments during the 12-hour days. The Northern Mariana Islands are generally short of visitors in October.
