@Jklotz - you asked about weather services. I'll answer in two parts - standard coastal cruising down to Panama (and across South America); and this run up the Caribbean.
WEATHER TOOLS - COASTAL CRUISING (<72-hour runs)
My arbitrary definition of coastal cruising is ability to run within a rolling 72-hour weather forecasts. As @ksanders hints, this allows a boat to go from Alaska to Panama relatively comfortably. Doesn't mean you'll stop, but it means you can bail-out if necessary. I've made many runs of >1000 nms with rolling 24-hour/72-hour that end up being favorable. Even if you don't bail-out, often coastal headlands provide opportunities for protection.
Our tools for Coastal Cruising:
No real bail-out options so once you leave, you're committed. For example, there are a few folks on TF who have circumnavigated - the longest run is the Pacific at 2200-ish NMS from California. A Willard 36 did it once and took 16-days. The N55 I'm on could do it in 12 or so. That's well beyond reliable forecasting. This run up the Caribbean is sort of a baby-step version of extended cruising, at least the route we're taking now (with my Willard 36 Weebles, I'll adjust to make it much closer to Coastal Cruising).
Our tools for extended cruising:
There are plenty of ways to skin this cat. Above is our approach. I will say the Caribbean has been a learning curve as the weather patterns are different than the Pacific. On my to-do learning list is to understand the 500mb charts better. This should give better long range visibility for me.

Our tools for Coastal Cruising:
- PredictWind (the mid-level $250/yr subscription that allows routing and departure planning)
- Windy (I did upgrade to Pro version at $30/yr)
- OTHERS
- TimeZero Weather Overlay. The N55 I'm on has this capability which is pretty cool. Would offset PredictWind. I believe some features are free with current version of TZ, other features are $$$.
- BuoyWeather - I haven't used this for several years but used to find it useful, especially for day-outings.
- OpenCPN - has Weather Plug-Ins. It's been a while since I used them so maybe they're better, but they were clunky as heck.

Our tools for extended cruising:
- Pilot Charts (or similar). These show historical weather patterns to help decide when a passage is prudent. These are old-school tools that are sorta fun to study. Located HERE. For example, when we took Weebles from San Francisco to Ensenada, a 500 nm run, we waited until Sept/Oct when the weather is historically calm. Gorgeous run! With Weebles going up the Caribbean, I'll make the run closer to April/May when the weather is historically better. PredictWind has some interesting historical analytics too.
- Chris Parker Weather Router. The owners hired a professional weather router - Chris Parker is very well known. He was pretty helpful to identify extended departure dates. For example, he could tell 10+ days out if a favorable pattern was likely to develop.
- PredictWind - Pro Subscription ($500/yr). This gives more granular routing but more importantly for these waters, gives planning with respect to currents: The Gulf Stream. GS info is available elsewhere (Windy has currents) but to get actual routing, PW Pro is a good choice (BTW - an App call "FastSeas" is an overlay using Windy as the underlying engine and will route relative to currents so is a possible alternative at $60/yr). For the Pacific, the extra $250/yr really isn't needed.
- NOAA/OPC Synoptic Charts (Atlantic side located HERE - Cuba/Florida are in the lower left corner). The 48-hour surface forecast is pretty useful as it shows forecast movements of fronts and lo/hi pressure systems. Below is the one for right now.
