Climate
The weather in Costa Rica is characterized by two different seasons. The dry season in the highlands and on the Pacific coast prevails from November to April, the rainy season runs from May to October. However, it usually only rains in the afternoon, but then in abundant showers. The average temperatures on the coast are at 30°C (86°F) and in the highlands at 23°C (73°F).
Cocos Island has its own climate which is characterized by high humidity. The average air temperatures are at 28°C (82°F). The seasons are not as pronounced as on the mainland. Showers are frequent. Whatever the weather, the diving is first class all year round.

Health
Tetanus, polio, hepatitis A and B vaccinations are highly recommended.
Your doctor or travel clinic is the best source of information about preventive measures, immunisations (including booster doses of childhood vaccinations) and disease outbreaks overseas. Please consult with them to get up to date and personal health advice for your trip.
The standard of medical facilities and medical care in many countries is significantly lower than those in Australia. There can be shortages of medical equipment and medicines and hygiene can be poor. Upfront payment is required in some countries before treatment will begin. In the event of a serious illness or accident, medical evacuation to a destination with appropriate facilities may be necessary. The costs for medical evacuations can exceed $100,000.
If you are planning to visit Costa Rica mainland, Malaria and other insect-borne diseases are common in many regions. We encourage you to take prophylaxis against malaria and use insect repellent. Water-borne, food-borne and other infectious diseases are prevalent around the world with major outbreaks occurring from time to time. We encourage you to consider having vaccinations before travelling.
Currency
National currency is the Costa Rica Colon (CRC).
Before you go, organise a variety of ways to access your money overseas, such as credit cards, travellers' cheques, cash, debit cards or cash cards. Australian currency and travellers' cheques are not accepted in many countries. Consult with your bank to find out which is the most appropriate currency to carry and whether your ATM card will work overseas.
