Notes About Jaco
In the high season (Mid-December through April), Jaco Beach daytime temperatures are generally in the upper 80’s and nighttime lows are in the 70’s. In the green season (May through Mid- December), daytime highs are in the low 80’s and nighttime lows are in the lower 70’s. Expect rain in the green season, though it is likely to be preceded by sunshine and followed by sunshine. Rain is less likely in the high season but is not uncommon. Since San Jose is at a higher altitude, it can get chilly in the evening – particularly in the green season.
Jaco is extremely casual – shorts, swimwear and sandals are okay everywhere. Long pants are unnecessary for Jaco but may be desired for San Jose or any special events you may have planned. The sun can be intense here, so remember your sunscreen, hat, sunglasses and lightweight long-sleeve shirt. Flip-flops or beach shoes are a good idea to bring with you.
Safety and personal security are essentially the same in Costa Rica as in any tourist destination. Use common sense and reasonable caution. If someone offers to help or chat politely decline and keep a close eye on your personal items.
All restaurants and businesses in Jaco accept payment in U.S. dollars and most will take credit cards. You can exchange dollars for colones by paying in dollars and receiving change in colones and they should give you a fair exchange rate which is currently around 565 colones = $1 USD. Restaurants may not accept bills larger than $20 so bring a lot of smaller, fresh/crisp bills. ATMs are available throughout Jaco.
DO NOT bring travelers checks and definitely don’t change your money at the airport because the exchange rates there are terrible. All business will take US dollars.
