Warmest 96 °F (35.7 °C) on May 19 at 3:05 PM; coldest 24 °F (-4.4 °C) on Apr 21 at 6:05 AM.
Thursday, Sep 17, 2026. Total since records began here: 24.82 in (630.4 mm). Last 24 hours: 0.00 in (0.0 mm).
Recorded Apr 6 at 11:20 AM. Typical wind here: 1 mph (0.3 m/s).
Ranged 4–47%. It jumps after rain and slowly dries out as plants pull water up and it drains deeper.
A quick guide to each measurement on this page — no science degree needed.
What it is: How warm the air is, measured in a shaded, ventilated shield about 2 m (6 ft) above the ground.
Why it matters: It sets the weather we feel, and it warms or cools the water and soil around it.
📏 Coastal stations stay milder than inland ones — cooler on summer afternoons, warmer on winter nights.
📍 Here: typically 61 °F; 24 °F to 96 °F so far.
What it is: The temperature the air would have to cool to for dew or fog to form. Unlike humidity, it does not change just because the air warms up during the day.
Why it matters: It is the best measure of how muggy it feels and when fog will form.
📏 Dew point above ~65 °F (18 °C): sticky. Below ~50 °F (10 °C): crisp. When air temperature falls to the dew point, fog forms.
📍 Here: typically 54 °F; 9 °F to 76 °F so far.
What it is: How much water vapour is in the air compared with the most it could hold at that temperature.
Why it matters: High humidity feels muggy, means fog and dew are likely, and slows evaporation.
📏 100% means the air is saturated — fog, dew or rain.
📍 Here: typically 82%; 19% to 100% so far.
What it is: Average wind speed, the strongest gust, and the direction the wind is blowing from.
Why it matters: Wind builds waves, pushes water against the shore, mixes oxygen into the water and dries out soils.
📏 Light: under 10 mph. Breezy: 10–20 mph. Strong: 25+ mph. Gale: 39+ mph.
📍 Here: typically 1 mph; 0 mph to 7 mph so far.
What it is: Rain measured in a gauge, totalled for each hour and day.
Why it matters: Rain washes fresh water, sediment, nutrients and sometimes pollution off the land into ponds, marshes and the bay — watch salinity drop and turbidity rise after a big storm.
📏 1 inch = 25.4 mm. A summer thunderstorm can drop an inch in an hour; Maine averages about 45 inches a year.
📍 Here: 24.82 in (630.4 mm) since Apr 2026.
What it is: Solar radiation (W/m²) is the total energy arriving from the Sun. PAR (photosynthetically active radiation) is the part of that light plants can use, counted as light particles (µmol/m²/s).
Why it matters: Sunlight powers photosynthesis on land and in the water, and warms the air and ground.
📏 Midday summer sun ≈ 1000 W/m²; heavy overcast ≈ 100 W/m². It is zero at night.
📍 Here: brightest so far 1196 W/m².
What it is: Temperature of the ground at several depths below the surface.
Why it matters: Soil warmth controls when seeds sprout, roots grow and insects become active. Deeper soil changes slowly and lags the seasons — it is the last to cool in fall.
📏 Near the surface it follows day and night; at 45 cm (18 in) it barely changes from day to day.
📍 Here: typically 60 °F; 36 °F to 73 °F so far.
What it is: How much of the soil, by volume, is water.
Why it matters: Plants depend on it; very wet soil means rain runs off instead of soaking in, very dry soil means drought stress.
📏 Roughly 10–20%: dry. 20–35%: moist. Above 40%: soaked. It jumps after rain, then slowly drains and dries.
📍 Here: typically 13%; 4% to 47% so far.
All measurements on one shared timeline. Use the buttons to zoom to the last day, week or month, or drag across any panel. Click a name in the legend to hide or show it.
One arrow per day, newest month at the top. Each arrow points the way the wind blew (like a weather map), and the bigger the arrow, the windier the day: calm days shrink to a dot, and the biggest arrows are days averaging or more. Hover or tap an arrow for the date, where the wind came from and its average speed.
Each day's range (shaded) and average (line); bars are daily totals.
Each wedge shows how often the wind blows from that direction; colours show how strong. Distance from the centre = % of the time.
Averages, lows and highs for each month (newest first).
