May ties April for Aruba's driest month at 5.3 rain days on average, with highs climbing to 83.8°F and humidity at 80%, the highest reading of the dry-season stretch so far.
Lows warm further to 79.3°F, and this is where Aruba starts feeling genuinely hot rather than just warm, though the ever-present trade winds keep it from feeling oppressive the way similar temperatures would elsewhere.
The sea warms to 81.6°F, comfortable and clear, with good visibility for snorkeling and diving around the island's reefs and wrecks.
No hurricane activity has been recorded historically for May, and Aruba's position south of the main Atlantic hurricane track means even as the wider Caribbean's season approaches, this island stays a comparatively low-risk pick.
Rates typically stay reasonable through May as the winter high season has fully wound down and summer family travel hasn't yet begun, a solid value month for dry, warm, breezy weather.
Windsurfing and kitesurfing conditions remain excellent, and May is a good month for the island's less crowded beaches on the northern and eastern coasts, like Boca Prins or the area near the California Lighthouse, for travelers wanting more solitude than Palm Beach offers.
Arikok National Park remains comfortable to explore, though the rising heat makes an earlier start to any hiking or off-road excursion the smarter choice.
Compared to Aruba's Caribbean neighbors, May here is notably drier and lower-risk, most other islands on this site see rain and storm activity start climbing by now, while Aruba holds steady.
Pack light, breathable clothing, strong sun protection, and a windbreaker for the steady trade winds.
