- Puerto Rico's temperature does not vary much from summer to winter, as the island is in the tropical zone climate-wise. The lower elevations will vary between 70 and 90 degrees, with the higher mountainous areas 10 degrees cooler. Perhaps 6 degrees separate winter from summer. The average daily highs in August and September reach 88 degrees with the highs in January and February being 83. The southern part of Puerto Rico is only a few degrees warmer than the north. Wind speeds in Puerto Rico are steady and somewhat strong, as the island is in the direct path of the trade winds.
- Puerto Rico's mountains cause great discrepancies in rainfall totals across the island. Some areas will receive large rainfall amounts while others a short distance away will get hardly any precipitation. The rain will be heavy on the northern side of the mountains, located in central Puerto Rico, and be much lighter on the southern side. The coolest temperatures are found in the higher elevations.
- Puerto Rico's rainy season lasts from April to November. The rest of the months comprise the dry season, although it can rain briefly each and every day, on occasion. Rain showers usually are hit and run in Puerto Rico, with most lasting no longer than just 20 minutes.

The last significant hurricane to hit Puerto Rico occurred in 1998, when Hurricane Georges came ashore with torrential rains and strong winds, causing incredible damage.
