Weather and where to get it;
Many yachts with HF radio have a modem attached so that they can receive short emails and weather at sea. Unfortunately we could not purchase a modem anywhere without weeks of waiting so we relied on weather info gathered whilst in port or in few cases relied on our mate Rick in Oz who we contacted via satellite phone to give us a weather report.
Naturally the best is to have the modem pack with the HF radio and order your weather through Sailmail. However, many yachties know that even if you have the information at hand when you are out there, there is not much you can do about the weather if it turns bad. I know that when we were crossing the Colombian Basin and needed weather information to make a quick decision on a change of course I would not have been able to get that through the HF radio system as you have to order your weather report and that would not arrive until the next morning. I phoned Rick and got it within the hour and we were able to cut 50 Nms off the passage.
One of the better ways is to get the weather that is broadcasted on the HF radio by a regular network or by another yacht that is remaining in a port whilst you are on passage and they keep a radio sched with you and give you the weather.
The other way is go outside and look at the sky regularly, learn the signs.
There are some good long forecasting sites on the internet for the Pacific one of the best is Metvuw from NZ. They have a good website and have 3 and 7 day surface charts.
Another good website if you have someone in a port that can obtain the information for you is buoyweather, this site one can select the customise button find the Lat/Long of the yacht and it will give the weather at that position for the next 24 hours, it gives wind speed and direction, wave height and direction and time intervals of the waves.
If you are waiting somewhere for the cyclone season to finish and you are trying to work out if there is anything happening there are two good sites. One is the Cyclone and Storm tracking and the other is the Madden Julian Oscillation Index.
I learnt more about the MJO waiting for this cyclone season to finish and the mongrel caught me out, we thought it was over it reached its eighth phase and was not measurable. We thought that’s it, but the mongrel got going again after we set sail and that is part of what we copped between Tonga and Fiji, it started a cyclone north of Vanuatu and created the convergence zone through Fiji and Tonga.What is the MJO you may ask, the Madden Julian Oscillation is the low pressure systems that start off of South Africa and move eastwards across the top of Australia and through the Pacific to Southern America. It has eight phases. Phase 3 is just NW of Western Australia, Phase 6 is NE of Australia near New Caledonia these low pressure systems create the rain and cyclones in that part of the world.
There are many helpful websites and probably a lot more than I have found, the following is a list of what I have found or been given, they will help you plan you passages. Wait for the best weather window before setting off with careful planning the passage can be pleasant. But unfortunately sometimes the planning falls down because Mother Nature gets a little smarter than the weather forecasters and we get squalls and storms develop after leaving, but that does not happen all the time.

When in any port there is often a local cruisers network on VHF radio, this can be on any channel so ask around when you arrive. They are usually run around 0800 to 0830 hours local time and they usually have a weather section along with other information. Many places will give you some warning that the net is about to start on CH16 and allocate the frequency that it will be held.
Some of the HF Radio networks are seasonal or not always operating during our time crossing the Pacific some sailors staying back in port would give weather reports for yachts underway. For example I stayed in Raiatea for a month and provided weather reports and scheds at 0800 hours and 1700 hours daily getting their lat/long, speed and course at the 1700 hour radio sched, I would then work out their possible position in the morning sched and provide the weather for their locations using the internet weather stations for information. I had one yacht going to Vanuatu, one to Tonga and another to Rarotonga. Other sailors did the same when we left. We always worked out a radio sched with all travelling yachts even though they were going to different destinations.
