Best time to visit Manuel Antonio: dry season and transition months
The best time to visit Manuel Antonio for a drier seasonal pattern is the January to March core described by Costa Rica's meteorological institute, IMN. Its regional account uses the historical period 1961 to 1990. April and December are transition months, with the rainy season beginning in early May. This is a way to compare seasons when choosing dates, rather than a forecast for the days you will spend on the coast.
Start with the activity you most want to do. A national park walk, a beach visit and a boat excursion involve different decisions once you arrive. The season helps shape that plan, while current conditions and local instructions determine what is suitable on the day. Keep a practical distinction between choosing a month and choosing when to enter the water or follow a particular path.
Rainy season and daily planning
Manuel Antonio weather needs a daily plan as well as a seasonal overview. The historical IMN regional account describes possible extreme rainfall and flooding in low-lying areas. Look at local conditions before setting out and follow instructions from staff responsible for your route or activity. Assess today's road, river or beach conditions separately from the monthly rainfall figure.
Leave room to adjust the order of activities, while keeping fixed bookings such as your park entry slot in view. Choose footwear for walking, keep the return journey in the plan and avoid fitting every outdoor activity into one tightly connected sequence. If a coastal outing is the priority, read the boat trip guide before deciding which day to reserve. A rainfall table describes the land climate; it does not settle the decision about going to sea.

Monthly climate table for Damas, Quepos
This older table comes from the Damas station in Quepos, reproduced in an INDER territorial study with IMN 2013 as its climate source. The normal period is not specified. Maximum and minimum columns represent mean maximum and mean minimum temperatures, rather than record temperatures. Use the figures as historical context for comparing months, not as a prediction for your travel dates.
| Month | Mean maximum °C | Mean minimum °C | Rainfall mm |
|---|---|---|---|
| January | 31.3 | 21.8 | 59.9 |
| February | 32.0 | 22.0 | 29.5 |
| March | 32.5 | 22.8 | 44.7 |
| April | 32.2 | 23.5 | 164.3 |
| May | 31.2 | 23.4 | 427.9 |
| June | 30.7 | 23.2 | 415.7 |
| July | 30.6 | 22.9 | 447.9 |
| August | 30.5 | 22.8 | 492.2 |
| September | 30.4 | 22.9 | 549.5 |
| October | 30.0 | 22.7 | 615.6 |
| November | 29.8 | 22.8 | 390.6 |
| December | 30.6 | 22.4 | 155.7 |
The table is useful for understanding why a flexible outdoor plan matters. Read temperature and rainfall as different parts of the picture: warm conditions do not settle whether a walk or water activity should proceed. For travel days, combine the seasonal context with the practical route choices on getting to Manuel Antonio.
Boats, rafting and paths in wet weather
The wooden sailing ship offered here is a coastal outing, with snorkelling equipment among its included items. The included equipment and the day's conditions are separate questions. Sea state matters for the outing, and neither the season nor a booking promises a particular underwater view or an animal sighting. Choose the experience for its coastal setting without building the day around seeing a particular species.
For rafting excursions, use the specific trip's participation requirements and the crew's assessment of conditions. A river excursion offered throughout the year still depends on the situation on the day. In the national park, stay on designated paths and follow staff and signs. Treat old route maps as orientation rather than permission to enter a section. At the beaches, pay attention to flags, weather and local instructions before swimming.
Park rest day and booked arrival slots
Weather is only part of choosing your park day. As checked on 11 November 2026, the ICT regional guide gives Wednesday to Monday, 07:00 to 15:00, as the official planning orientation, with Tuesday closed. Keep that rest day separate from seasonal thinking: choosing a drier month still requires choosing an operating day.
Tickets are bought online for a named visitor, visit date and arrival slot. Have your identification and purchase code ready and organise the journey to meet your booked time. Read the park ticket guide before tying admission to a transfer or guided outing. For a visit centred on wildlife, the guided walk page explains the park experience; wildlife remains free-ranging whichever month you choose.
Weather and season questions
Which months have the drier seasonal pattern?
IMN's regional description, based on 1961 to 1990, identifies January to March as the drier core. April and December are transition months. Use this as seasonal context alongside current weather information.
Is the monthly table a forecast?
It is an older Damas station table using an IMN 2013 source, with no stated normal period. Use its monthly figures as historical context, and consult a current forecast for the weather during your stay.
Can I choose any day for the national park?
Tuesday is the rest day according to the ICT guide checked on 11 November 2026. Select an operating day and an online arrival slot, then organise transport around that booking.
