It is a natural dark sandy beach, absolutely virgin. Millions of pebbles are washed up on shore. They are all smooth though so no problem with injuries or kites being torn.
Air temperatures are very warm; probably in the 80's°F all year round. Very cool at night and in the mornings. It rains every night so if you are gonna camp, make sure your tent works. No wetsuit needed all though when it rains the water gets a little chilly but still very nice. The season is year-round. The climate doesn't change much. It's either raining or sunny and windy.
The wind is usually onshore about 20-30 knots during the day and can shift to side winds either way. Very unpredictable as far as direction, but always wind. The beach faces West.
To get there you just need to take an AVIANCA or TACA airline flight to Bogota or Medellin. Usually around 350-550 dollars from the USA. Arrive, exchange some cash for Colombian peso, and charter a small plane right into Nuqui. The kite beach is west of the airport and there are probably 3 or 4 cabs in the whole town. But the nice hotel is a 15min walk to from the airport and the locals will carry your bags for a tip (1 dollar).
The river Nuqui divides the beaches `Nuqui Kite Beach` and `Olimpica`. Life vest would be nice since the water can get rough. This area can be very dangerous for tourists due to kidnapping.
