Cabo weather in May
May brings hotter afternoons to Cabo San Lucas, while nights remain cooler than in late summer. It is historically very dry, but it also crosses an important calendar boundary: the official eastern Pacific hurricane season starts on 15 May.

Rain and seasonal conditions
The May rainfall normal is small. This does not mean that the second half of the month sits outside cyclone season or that unusual weather is impossible. Use the season dates and live advisories as well as the climate average when planning.
Swimming and time on the water
Air temperatures rise faster than your comfort in the ocean necessarily will. Ask local providers about water temperature, visibility and flotation or thermal protection for the activity you book. Do not assume that every early-morning paddle has calm conditions.
Planning activities in May
Beach time, a meal featuring local seafood or farm produce, and a boat or guided paddling trip are possible ways to structure a visit. Start demanding land activities before the hotter part of the day and keep time for shade. Confirm business hours and the actual operating itinerary before traveling.

What to pack
Bring breathable clothing, sun protection, drinking water and swimwear. A light layer can still help for a breezy return journey or evening. If you plan an excursion, confirm what gear and transport are actually included.
Dates, bookings and flexibility
May can be an option for travelers comparing dates around the busier winter period, but prices depend on the exact stay and product. Check change and cancellation terms, and do not assume a low-rain month removes weather-related disruption from the decision.
An additional visitor perspective
The retained video provides additional travel context. Use current official forecasts and operator information for decisions about your own dates, rather than treating the video as a weather forecast.
