I feel that Conrad is generally hotter than the other resorts I have visited. Somehow not many shelters and shades perhaps.
Hot, 30-32 Deg C everyday but great for sea sports or lazing around the pool.
It was mid-August, on the day of our seaplane ride, it rained and water was bumpy/rough. But for the rest of week, it was hot, extremely hot. Not recommended without hat and sunblock / sunscreen. Since it is August, water would be still be somewhat rough on some days are better that others.
