Cancun is the clearer pick — 71 vs 61 on the Atlas Ranger Score, our 0–100 measure of weather, crowds, value, and timing across the year. It leads most of the year, though the month-by-month chart still shows the other's stronger windows.
Cancun averages a higher weather score (67 vs 54). Weather is the biggest input to the score, but both have strong months and weak months; the month-by-month chart shows exactly when.
Both have similar off-peak windows. The cheapest time for either is its shoulder/low season — outside the peak-weather months when prices spike.
Often yes — many travellers pair them. The smart move is to time each leg to its own best months. Check each destination's full guide (linked below) for the month-by-month detail, then sequence your trip so each stop lands in its strong window.
