Swell Marching to Central America.
Looks like a great time to be in Costa Rica later this week.
Continued below...
Swell from a storm that slipped off the Antarctic Ice-pack last weekend is setting up overhead swell for the region.

Take a look at the 5-day forecast graph showing the progression of swell height, wave period, and direction over time. This output represents the swell height in deep water, prior to breaking. That blue colored lump setting up Thursday/Friday should put overhead waves at exposures, while standouts are even BIGGER.

These waves spread to most the West Coast, including California bringing really fun waves for open spots towards the close of the work week. Be sure to dial into your local Surfline forecast for details -- Charlie Fox

WHAT IS LOLA?

LOLA is the world's only automated global surf forecasting tool. LOLA can forecast waves right down the street, or it can predict surf conditions at the top spots around the globe - breaks like Tavarua, Tahiti and Jeffrey's Bay.

LOLA uses the NOAA Wavewatch III engine (running on our own computers) with Surfline-modified data from various wind models (AVN, GFS, MRF). Then LOLA combines this information with empirical data we've programmed into her gained from over 30 years of surf and weather analysis here at Surfline.

LOLA also gathers real-time data from offshore buoys to measure wave pulses from storms around the world every hour. She taps into orbiting satellites to measure hurricane-force winds and tremendous wave heights in the heart of raging storms when huge ships are running for cover. She computes near-shore wave animations measuring detailed wave heights along the coast, taking into account how swells are distorted by offshore islands and the continental shelf.

When you add it all up, LOLA is the ultimate forecasting tool for surfers looking for timely, accurate and comprehensive information about waves.

Initially, we created LOLA as a proprietary tool for Surfline forecasters. But we decided to share the knowledge and give Surfline's Premium Members the chance to use LOLA themselves, to give them the best chance to score more good surf more often.
