Cached-fare history: across 4 months, Feb is the cheapest for MAD → SJU. Best time to be there: Dec–Apr.
Fares bottom out in February around $719 and peak in December near $1,063 — a $344 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13.5 hours outbound, on a 9-night trip — ticketed under Avianca, which on a connecting fare need not operate every leg. At $719 for 6,374 km each way, that works out to about $56 per 1,000 km flown. That is above the $44 typical of long-haul fares here. Across the 13 departure cities we track at a similar distance from San Juan, this fare ranks 3rd — 2.9× the $252 we hold from Los Angeles. For context, the middle fare among the 16 routes of similar length we watch out of Madrid is $646.

MAD → SJU, answered.
Is $719 a good price for Madrid to San Juan?
Only slightly. The seasonal median is around $850 round-trip and this fare is 15% under it, about $131. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Madrid to San Juan?
Across 4 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in San Juan are Dec–Apr — when those overlap, that's your window.
How far in advance should I book MAD → San Juan?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 4 months of cached fares, Feb comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Madrid to San Juan?
The current cheapest fares involve a connection, ticketed under Avianca. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
