Oranjestad, Aruba
Pick your travel dates to see the odds.
August brings Aruba's warmest reading yet, 85.2°F highs, 80.4°F lows, with humidity easing slightly to 79% and rain at 7.8 days on average. Notably, no hurricane or tropical storm activity has been recorded historically for August, a dip from July's 2 storm days.
The sea reaches 82.9°F, warm and excellent for swimming, snorkeling and diving, continuing the strong summer conditions.
August remains deep summer-holiday season for Europe and North America, so crowds and pricing stay elevated on the Palm Beach resort strip through most of the month.
The lack of recorded storm activity in August is a genuinely distinctive feature of Aruba compared to almost every other destination on this site, where August typically marks the real start of elevated hurricane risk.
Windsurfing and kitesurfing remain outstanding, and this is a strong month for exploring the island's less-visited eastern coast and Arikok National Park's desert interior before the year's heat peaks fully.
Value-minded travelers should note that despite the calm weather profile, August pricing still tracks the broader Caribbean's summer demand rather than Aruba's own lower risk, book ahead regardless of the favorable storm outlook.
This is a good month to combine a beach-focused stay with Oranjestad's cruise-port shopping and dining scene, since the capital's walkable downtown offers a comfortable change of pace from a full week of sun.
Pack for heat and humidity, sun protection, and a windbreaker for the steady summer trade winds.
