Unless you live in a special, unique place like Hawaii or Costa Rica it’s unlikely you’ll be able to surf every day. It’s not easy to plan surf sessions or even surf trips to most locations because the weather conditions will need to be just right. Not only the wave height (swell) but also the wind speed and direction, tide, water and air temperature, and even amount and type of marine life present can all impact your surf session. You’ll want something which can easily tell you right away if conditions are good.
This project from [luke] is called the Surf Window shows the surf conditions at the local beach with just one glance. Made out of various pieces of wood, each part represents one of the weather conditions at the beach. A rotating seagull gives the wind direction, for example, and the wave height is represented by 3D, moving waves. All of the parts are connected with various motors and linkages to an Arduino Mega +WiFi R3 which grabs all of its information from Magicseaweed, a surf forecasting site.
The Surf Window can show the current conditions at virtually any surfable beach in the world, so if you really want to know how Jaws, Mavericks, or even Reef Road is breaking right now, you could use this to give you a more nuanced look. Don’t forget to take the correct board for the conditions!

Before the information age, it wasn’t quite as easy to glean information about the weather. Sure, there were thermometers and barometers and rhymes about the sky, but if you lived in or near Germany back then you might have also had access to something called a “weather house” which could help predict rain. [Moritz] aka [Thinksilicon] found one of these antequated devices laying around, and went about modernizing it. (Google Translate from German)
A traditional weather house is essentially a hygrometer housed in an intricate piece of artwork. Two figures, typically a man and woman, are balanced on a platform that is suspended in the middle by a small section of horsehair. When the humidity is low, the hair tightens up and turns the platform one way, and when humidity is high — suggesting rain is coming — it turns the other way. When the man comes out of the house, it predicts rainfall.
To get the weather house upgraded, [Moritz] outfitted the front with an OLED display which replaced the traditional thermometer. Instead of using horsehair to spin the figures he installed a small servo on the platform. The entire house is controlled by an ESP8266 which pulls data from the Open Weather API and spins the figures based on the information it receives.
Much like unique clocks, we enjoy interesting weather indicating/forecasting builds. This one’s right up there with using squirrels to predict the weather, or having a small weather-recreation right on your bookshelf.
This project takes an umbrella stand and gives it the ability to let you know if you need to take an umbrella when you leave the house. The image above is a concept drawing, but a first prototype was built and seems to work quite well. See for yourself in the video after the break.
The project was put together by openPicus. They sell a prototyping module called the Flyport which provides a WiFi connection to your projects. This board connects to a set of LEDs which are used to illuminate the translucent plastic umbrella stand. But you might not notice the color change if the LEDs were always on. Also designed into the system is a PIR motion sensor. When you walk toward the door to leave for the day it switches on the appropriate color — green for clear, blue for raining, and red for storming — catching your attention in time to grab an umbrella as you pass by.
You don’t need to spend a bundle to pull off a hack like this. You can scavenge for a PIR sensor, use one color of LEDs just to tell you when rain or storms are forecast, and an ENC28J60 is a cheap and easy Ethernet alternative to using WiFi.
