Good question! The “Accu-Weather” information we include here isn't always the most accurate. The closest weather station isn't updated automatically, rather it relies on the weather observations being “phoned in” - which may or may not happen with fixed regularity. Additionally, the micro-climates within Costa Rica make prediction of weather much less scientific than in other places. It could be raining in one place while the sun is shining ½ a mile away. You can consider it a guideline, though.
October is wet. It's the wettest month of our year. We average 30" of rain in October. If you come in October, you will get lots of rain, but it can also be a wonderful, quiet time in Manuel Antonio. My brother and his wife spend a week here each October; it's a nice change for them and they love the occasional lightning and thunder storm.
In November the green season is ending and Summer is slowly approaching. Expect rain, but not as much as October.
This is our "peak season" for good reason; it's hot, dry and beautiful while most of North America is COLD! You can expect mid to high 80's and lots of humidity. Beautiful, blue skies with lots of big, white clouds. Spectacular sunsets. Perfect days for the beach, tours and activities! Maybe an occasional afternoon shower once a week to cool things off.
