The sea is generally comfortable for swimming throughout much of the year, but wind, waves, currents and cold fronts can matter more than the temperature alone.
Quick answer
Typical seasonal averages are roughly 24–26 °C during winter and 28–30 °C during summer. These are historical ranges, not a guarantee for a specific day.

Why a warm sea may still be unsafe
Water temperature only measures warmth. A beach can have warm water and still be unsuitable for swimming because of waves, currents, lightning or dangerous weather.
- North winds: can produce rougher conditions during winter fronts.
- Rip currents: may occur even on attractive sunny days.
- Thunderstorms: require leaving the water promptly.
- Red flags: should always be respected.
- Low visibility: can make snorkelling or swimming less comfortable.
Beach flags come first
Never enter the water only because it feels warm. Follow lifeguard instructions and the flag system used at the beach.
Best conditions for families
Families should look for a calm sea, manageable sun and a supervised beach area. Children can become tired, cold or dehydrated faster than adults, especially after long periods in the water.
- Use shade and schedule regular breaks.
- Keep drinking water available.
- Use sun protection and reapply it after swimming.
- Keep young children within arm’s reach.
- Leave the water if waves or currents increase.
Morning or afternoon?
Morning conditions are often calmer, but this is not a fixed rule. Wind and thunderstorms can develop later in the day, particularly during the wetter season. Check the beach directly rather than relying on yesterday’s conditions.
Swimming, snorkelling and marine life
Warm water does not guarantee good snorkelling visibility. Wind, sand movement and waves can reduce clarity. Travellers should also avoid touching coral, feeding fish or standing on reefs.
What to check before a beach day
- Current weather and wind.
- Beach flags and lifeguard instructions.
- Wave height and visible currents.
- Thunderstorm or tropical-weather alerts.
- Sun, hydration and medication needs.
