Seasons in Uvita: when to see whales and what weather to expect

Dry season, rainy season and the two humpback whale seasons that make the South Pacific unique.

The climate

SINAC describes the park's climate as hot, rainy and very humid (tropical wet forest), with two clear seasons:

  • Dry season: mid-December to mid-April, with occasional showers.
  • Rainy season: mid-April to mid-December.

Humpback whale seasons

According to SINAC, humpback whales arrive in two seasons: northern-hemisphere whales from December to April and southern-hemisphere whales from July to November. Resident dolphins can be seen all year. The ICT highlights that every year, from July to October, humpbacks arrive for their breeding cycles, turning the park into a natural stage.

Tips by season

  • In the rainy season, mornings are usually best for the beach and sea tours.
  • All year: check the tide table; the Whale's Tail and Arco Beach are only reachable at low tide.
  • Bring a hat, water and sunscreen, as SINAC recommends.
