Stop picking the destination first. Pick the week and let the weather decide.

Full disclosure: Coconut is made by the same people behind BRO. We use it. You should know that before you take our word for any of this.

Every travel site works the same way. You pick a place, you pick dates, and it shows you a price. Then you find out it rained the whole week.

Coconut runs it backwards. You tell it when you can travel and what weather you want, and it goes and finds the destination. It's the right question for anybody with a fixed week off, a family calendar, or a boss who approved Thursday to Tuesday and not a day more.

The coconut score, and why it isn't a temperature

Every place on the site carries a score out of 100 for how pleasant it'll actually be outside, shown as one to five coconuts. It's deliberately not a number of degrees, because a "78" next to a column of temperatures gets read as 78 degrees.

Here's what goes into it, straight from how the site explains itself:

• How it feels, not the raw temperature. 32°C at 85% humidity in Cancún and 32°C in Phoenix are different days, and the score treats them that way.
• Rain counts twice. Both the chance of rain and how much. A 90% chance of drizzle isn't a 40% chance of a downpour.
• Sun and wind adjust it. Wind above about 28 km/h starts to spoil a beach day.
• Heavy rain and extreme heat are vetoes. A warm day can't outvote a washout, and 46°C in the desert doesn't beat a mild week just because it's hot.

The weighting is public: 45% temperature, 30% rain, 15% sun, 10% wind. The forecast only runs about 16 days out, and past that Coconut shows nothing rather than guess. That's the right call. A made-up number at the moment you're spending money is worse than a blank.

Why it finds trips you'd miss

• It knows what's normal. Every fare gets scored against months of history for that exact route and trip length. "$749" means nothing on its own. "31% under the usual price" does.
• It watches while you don't. Set what you want and it tells you when a deal lands.
• It counts the drive. A cheap flight into an airport two hours from the beach isn't cheap.
• It rechecks before you book, so the price you saw is still the price.
• It looks past the usual dozen. The "rare finds" are the places most people never think to search.

There's also a 14-day grid that colors one square per day on the same scale, so you can scan across and spot a run of good days instead of trusting one forecast.

How a dad actually uses it

1. Put in the week you've got, not the place you've been daydreaming about.
2. Set the weather bar. "At least" rules places out completely. "Ideally" just decides the order.
3. Scan the list and the 14-day grid. Look for a run of good days, not one perfect afternoon.
4. Price the one or two that look right. That's the part that costs Coconut money, so it's the part they meter.
5. Set an alert if nothing's quite there yet, and let it watch for you.

What it costs

Finding where to go is free, on every plan, forever. What you pay for is pricing the whole trip, flights and hotels together, which takes about thirty seconds a search.

• Free: unlimited weather search, one fully priced trip a week, and a weekly deal email.
• Premium, $39 a year or $4 a month: 150 priced trips a year, all-inclusive and flight-plus-hotel pricing, instant deal alerts, and the trip builder.
• Elite, $149 a year: for people who travel a lot, with premium cabin fares and same-day mistake-fare alerts.

You can cancel in two clicks from your own account page, with no phone number to hunt for. That tells you something about who built it.

The bottom line

If your week off is fixed and your patience for rain is low, stop starting with the destination. Start at coconut.com, give it your dates, and let the weather make the first cut.
